Total Customer Satisfaction –PCB
Piezotronics guarantees Total Customer
Satisfaction. If, at any time, for any
reason, you are not completely satisfied
with any PCB product, PCB will repair,
replace, or exchange it at no charge.
You may also choose to have your
purchase price refunded in lieu of the
repair, replacement, or exchange of the
product.
Service –Due to the sophisticated
nature of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted,
may void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to insure that liquids are not permitted to
migrate into devices that are not
hermetically sealed. Such devices
should only be wiped with a dampened
cloth and never submerged or have
liquids poured upon them.
Repair –In the event that equipment
becomes damaged or ceases to
operate, arrangements should be made
to return the equipment to PCB
Piezotronics for repair. User servicing or
repair is not recommended and, if
attempted, may void the factory
warranty.
Calibration –Routine calibration of
sensors and associated instrumentation
is recommended as this helps build
confidence in measurement accuracy
and acquired data. Equipment
calibration cycles are typically
established by the users own quality
regimen. When in doubt about a
calibration cycle, a good “rule of thumb”
is to recalibrate on an annual basis. It is
also good practice to recalibrate after
exposure to any severe temperature
extreme, shock, load, or other
environmental influence, or prior to any
critical test.
PCB Piezotronics maintains an ISO-
9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceability to SI through
N.I.S.T. In addition to the normally
supplied calibration, special testing is
also available, such as: sensitivity at
elevated or cryogenic temperatures,
phase response, extended high or low
frequency response, extended range,
leak testing, hydrostatic pressure
testing, and others. For information on
standard recalibration services or
special testing, contact your local PCB
Piezotronics distributor, sales
representative, or factory customer
service representative.
Returning Equipment –Following
these procedures will insure that your
returned materials are handled in the
most expedient manner. Before
Warranty, Service, Repair, and
Return Policies and Instructions

returning any equipment to PCB
Piezotronics, contact your local
distributor, sales representative, or
factory customer service representative
to obtain a Return Warranty, Service,
Repair, and Return Policies and
Instructions Materials Authorization
(RMA) Number. This RMA number
should be clearly marked on the outside
of all package(s) and on the packing
list(s) accompanying the shipment. A
detailed account of the nature of the
problem(s) being experienced with the
equipment should also be included
inside the package(s) containing any
returned materials.
A Purchase Order, included with the
returned materials, will expedite the
turn-around of serviced equipment. It is
recommended to include authorization
on the Purchase Order for PCB to
proceed with any repairs, as long as
they do not exceed 50% of the
replacement cost of the returned
item(s). PCB will provide a price
quotation or replacement
recommendation for any item whose
repair costs would exceed 50% of
replacement cost, or any item that is not
economically feasible to repair. For
routine calibration services, the
Purchase Order should include
authorization to proceed and return at
current pricing, which can be obtained
from a factory customer service
representative.

1.0 CHASSIS AND POWER SUPPLY
1.1 Introduction: Safety Considerations
WARNING 1: The power supply/signal conditioner
should not be opened by anyone other than qualified
service personnel. This product is intended for use by
qualified personnel who recognize shock hazards and
are familiar with the safety precautions required to
avoid injury.
WARNING 2: This equipment is designed with user
safety in mind; however, the protection provided by the
equipment may be impaired if the equipment is used in
a manner not specified by PCB Piezotronics, Inc.
Caution 1: Cables can kill your equipment. High
voltage electrostatic discharge can damage electrical
devices. Similar to a capacitor, a cable can hold a
charge caused by triboelectric transfer, such as that
which occurs in the following:
• Lying on and moving across a rug.
• Any movement through air.
• The action of rolling out a cable.
• Contact to a non-grounded person.
The solution for product safety: 1) Connect the cables
only with the AC power off. 2) Temporarily “short” the
end of the cable before attaching it to any signal input or
output.
Caution 2: ESD considerations should be made prior
to performing any internal adjustments on the
equipment. Any piece of electronic equipment is
vulnerable to ESD when opened for adjustments.
Internal adjustments should therefore be done ONLY in
an ESD-safe work area. Many products have ESD
protection, but the level of protection may be exceeded
by extremely high voltage.
WARNING SYMBOLS AND TERMS
The following symbols and terms may be found on the
equipment described in this manual.
This symbol on the unit indicates that the user should
refer to the operating instructions located in the manual.
This symbol on the unit indicates that high
voltage may be present. Use standard safety
precautions to avoid personal contact with this voltage.
This symbol indicates safety, earth ground.
The WARNING heading used in this manual explains
dangers that might result in personal injury or death.
Always read the associated information very carefully
before performing the indicated procedure.
The Caution heading used in this manual explains
hazards that could damage the instrument.
EQUIPMENT RATINGS
For complete specifications, please refer to the enclosed
Specification Sheet. This equipment operates at 104°F
(40°C), in an environment having 93% relative
humidity. Its frequency range is 50/60 Hz. Operation
of this unit is limited to environments having an altitude
of less than 2 000 meters. The pollution degree for
operation of the Model 440 is Two (2), meaning that
normally, only non-conductive pollution occurs. The
over voltage category is II, indicating the transient
voltage levels that may be tolerated by the equipment.
The Model 441A101 requires 100 to 240 VAC with 1.3
amps to operate. It gets its power via an AC line cord
that plugs into the receptacle on the rear panel. (The
Model 441A102 – DC supply does not use this
receptacle.)
Two rear panel fuses, located below switch in the AC
receptacle, protect the power line inputs of the
instrument. The fuse type is a T 1.6A, L 250 V. To
change the fuse, disconnect the power cord. Find the
slot just above the power switch and pull forward to
open the door that exposes the fuse drawers. Pull the
individual drawer forward and insert a new fuse. See
Figure 1.

1.2 DESCRIPTION
The PCB Modular Signal Conditioning System is a
flexible, compact means of coordinating and
customizing the signal conditioning needs of vibration,
pressure, or force sensing instrumentation. At its most
basic level, the system consists of a rectangular chassis
with a single-slot power supply on the right side of the
chassis and one module (customer specified). This
power supply is either AC or battery power, depending
on customer requirements. It should be noted, however,
that the AC and DC power supplies are separate units,
having differing part numbers. See Section 1.2.3 and
1.2.4 for a more detailed description of the power
supplies.
1.2.1 Chassis (Model 441A42, 441A43,
441A35, 441A39, 441A45, 441A49)
The chassis configuration varies, ranging from two slots
to nine; one of these slots (extreme right) is reserved for
the power supply. Situated on the rear panel behind the
power supply slot is a power entry module that includes
an on/off switch, fuses, and a power filter for use with
the AC power supply only. See Figure 1.
Euro card-style plug-in modules occupy the remaining
slots. For a complete listing of available modules, see
Section 1.4.
The standard chassis is constructed of molded plastic
with molded ventilation slots. The 19-inch rack-
mounted unit is constructed of metal.
The Model 441A33, 35, 39 are the computer controlled
versions of the standard chassis. The back panel of this
chassis has one RS-232 connector and two RS-485
connectors marked “in” and “out”. Also located on the
rear panel is a cooling fan.
A back plane on the inside rear of the unit unifies the
circuitry, routing it to the power supply. Individual
modules slide into the unit via the slot divisions and are
secured to the inside frame using mechanical fasteners.
Models 441A45 and 441A49 are “slave” racks designed
to be controlled by a “master” rack (441A33, 441A35,
441A38, 441A39). These racks do not have an RS-232
connector, but only two RS-485 connectors, which may
be connected to either a master, or another slave in a
daisy chain fashion. At least one master must be in the
system if it is desired to use computer control.
Located on the rear panel of these racks is a cooling fan,
which normally is on. If it is desired to turn off the fan
in order to reduce acoustical noise, a jumper “J2”
located on the motherboard must be removed. In order
to access this jumper, the rear panel must be taken off.
The fan may now be disabled via a command from the
host computer controlling the master. The fan should be
disabled for as short a period as possible to ensure
continuous cooling. Contact the factory for more details.
1.2.2 AC Power Supply (Model 441A101)
The Model 441A01 is a single-slot, CE marked, AC-line
power supply designed to fit only the extreme right slot
of the PCB Series 440 Modular chassis. It supplies a
maximum of 45 watts of power and may be used to
operate single or multiple signal conditioning modules
housed in the two-, three-, or nine-wide standard chassis
and optional auxiliary chassis.
The power unit supplies a maximum of 45
watts of power. Please note that while this
unit is rated for a maximum wattage of 45, CE
requirements mandate that it be used only up
to 30 watts.
Wattage calculations are found on the Specification
Sheet for the individual module. To determine power
capability of your particular set-up, use the following
procedure:

MODULAR SIGNAL CONDITIONING SYSTEM GENERAL OPERATION MANUAL
3
1. Add all the powers for all modules. CE mandates
that these totals must be <30 watts.
1.2.3 DC Power Supply (Model 441A102)
Model 441A102 is a single width, CE marked,
rechargeable DC battery power supply designed to fit
only the extreme right slot of the PCB Series Modular
chassis. It supplies a maximum of 30 watt/hrs and may
be used to operate single or multiple signal conditioning
modules housed in the two-, three-, or nine-wide
standard chassis and optional auxiliary chassis.
It can also be used with an external 12VDC supply like
a car battery by using the supplied DC power cord
Model 017A22. Or it may be line powered using the
optional Model 488A09 AC power adaptor. Both these
external power sources plug into the EXT DC jack
located on the front panel. Refer attached operation
guide for the Model 441A102 in appendix A.
1.3 MAINTENANCE AND REPAIR
Aside from battery replacement on units so equipped,
no maintenance is required for this modular unit, other
than wiping the exterior of the chassis with a soft cloth
when dusty. If you experience difficulty with your
particular unit, contact the factory for assistance.
Because of the sophisticated nature of PCB
instrumentation, field repair is typically not
recommended and voids the warranty. If factory
service is required, return the instrument to PCB. A free
quotation is provided prior to servicing.
To expedite the repair process, contact a PCB Customer
Service Representative for a Return Materials
Authorization (RMA) number prior to sending
equipment to the factory. Please have pertinent
information available, such as model and serial
numbers, application information, what instruments are
connected to the equipment, and so forth. Also, to
insure efficient service, be sure to include a brief written
description of the problem. International customers
should return equipment to a local distributor, or contact
PCB if no distributors are available.
PCB is an ISO 9001-certified company that has
embraced its company mission of TOTAL CUSTOMER
SATISFACTION. These two factors assure that if at
any time you are not satisfied with any of our products
or service, let us know and we will correct the problem.

battery. Data Protection is assured with the low battery indicator specified to come on at exactly nine
tenths of the battery life, giving adequate warning of Power shutdown. When the battery needs
charging, simply use the included 488A08 to quickly recharge the battery in about an hour.
Low noise operation is an added benefit of the 441A102 because of its’ Ultra High Technology DC-to-
DC converters.
Any PCB Modular Series Products can be utilized in a mobile test system with a very simplified and
reliable connection to the vehicles cigarette lighter socket, with the included 017A22 (3 Amp fuse
protected) DC Power cord.
Specifications:
See Specification Sheet for Model 441A102.
Operation:
The 441A102 can be used to power up to 30 watts of PCB modular series units. Simply slide it into the
enclosure, in the power supply slot, and tighten up the two mounting screws. Turn on the power switch
and it’s ready to go! The estimated battery life can be calculated by dividing 30 by the total number of
watts of all the units being used together. See each units Spec. Sheet for the number of watts to use in
your calculation.
The 441A102 will automatically turn off when the battery has reached complete exhaustion. The power
will remain “OFF” until the Power switch is turned off and back on again. Please review the attached
specification sheet for the Model 441A102.
Note” (1) Model 488A08 and Model 017A22 are supplied accessories. (2) The Model 488A09 AC
adapter is an optional accessory that is sold separately.
To charge the battery, do the following: (1) Turn power off on the front panel of the 441A102. (2) Plug
the Model 488A08 into the charger input jack. (3) The yellow charge light on the charger will light solid
during fast charge as indicated on the charger. Typical charge time for a totally depleted battery is 1.5
to 2 hours. After the battery is charged about 90%, the charge light will begin to blink (1/8 sec blink). If
possible, leave charger on with charge light blinking for another few hours to get maximum charge. The
battery is 30Watt/hrs. (4) Unplug charger and turn power on and run 440 series modules.

Note: The white charge status table printed on the charger explains the various charger light modes.
Remove the charger plug by pulling on the body of the connector, not the cord. This is a locking feature
to insure a good connection while charging. It is not recommended to charge the 441A102 while the
Power switch is “ON”. No damage will occur, but charge time will increase.
Note: The Model 441A102 can also be used with an external 12VDC supply like a car battery by using
the supplied DC power cord Model 017A22. Or it may be line powered using the optional Model
488A09 AC power adaptor. Both of these external power sources plug into the EXT DC jack located on
the front panel.
Caution:
The 441A102 has some components that will get hot under heavy loads. Do not remove the module
from the enclosures immediately after continuous heavy use. Let completely cool first.

Total Customer Satisfaction –PCB
Piezotronics guarantees Total Customer
Satisfaction. If, at any time, for any
reason, you are not completely satisfied
with any PCB product, PCB will repair,
replace, or exchange it at no charge.
You may also choose to have your
purchase price refunded in lieu of the
repair, replacement, or exchange of the
product.
Service –Due to the sophisticated
nature of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted,
may void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to insure that liquids are not permitted to
migrate into devices that are not
hermetically sealed. Such devices
should only be wiped with a dampened
cloth and never submerged or have
liquids poured upon them.
Repair –In the event that equipment
becomes damaged or ceases to
operate, arrangements should be made
to return the equipment to PCB
Piezotronics for repair. User servicing or
repair is not recommended and, if
attempted, may void the factory
warranty.
Calibration –Routine calibration of
sensors and associated instrumentation
is recommended as this helps build
confidence in measurement accuracy
and acquired data. Equipment
calibration cycles are typically
established by the users own quality
regimen. When in doubt about a
calibration cycle, a good “rule of thumb”
is to recalibrate on an annual basis. It is
also good practice to recalibrate after
exposure to any severe temperature
extreme, shock, load, or other
environmental influence, or prior to any
critical test.
PCB Piezotronics maintains an ISO-
9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceability to SI through
N.I.S.T. In addition to the normally
supplied calibration, special testing is
also available, such as: sensitivity at
elevated or cryogenic temperatures,
phase response, extended high or low
frequency response, extended range,
leak testing, hydrostatic pressure
testing, and others. For information on
standard recalibration services or
special testing, contact your local PCB
Piezotronics distributor, sales
representative, or factory customer
service representative.
Returning Equipment –Following
these procedures will insure that your
returned materials are handled in the
most expedient manner. Before
