Chapter 1 Introduction To The Universal Process Amplifier System
The Mantracourt Electronics Universal Process Amplifier System is based upon a concept of modular construction. By
adopting such a concept, it is possible to offer a great deal of flexibility of construction, to meet the wide and
varying needs of system building.
The system is centred on a Eurocard sized amplifier PCB, which consists in its standard form of, Central Processing,
and voltage and current Analogue output ports. Facilities are provided to connect a series of ‘plug in ’ option boards
for inputs, relay and communications outputs together with mains and low voltage DC power supply options.
A special Fast Analogue output module is also available to complement a Fast Strain Gauge input option.
The modular concept offers the opportunity for assembly in Surface Mount, DIN Rail and 19-inch Rack variants.
The system concept is described in diagrammatic form with the range of options listed. The options will be
described under the various Chapters as follows:
1. Introduction
2. Installation requirements
3. Power Supplies
4. Input Modules
5. Output Modules & Communications Information
6. The Amplifier Displays
7. Programming the Amplifier including essential INPUT CALIBRATION ROUTINES, which must be actioned. See

Chapter 2 Installation
In order to maintain compliance with the EMC Directive 2004/108/EC the following installation recommendations
should be followed.
Inputs:
Comms Port:
Analogue
Output:
Use individually screened twisted multipair cable. (e.g. FE 585 - 646)
The pairs should be :
pins 1 & 6
pins 2 & 5
pins 3 & 4
Terminate all screens at pin 1 of the input. The screens should not be
connected at the transducer end of the cables.
Use individually screened twisted multipair cable. (e.g. FE 118-2117)
The pairs should be:
-Tx & +Tx
-Rx & +Rx
Terminate screens at pin 1 of the input .
The screens should not be connected at the host port.
Use screened twisted pair cable. (e.g. RS 626-4761)
Terminate screen at pin 1 of the input.
The screen should not be connected at the host port.
Pin 1 of the input should be connected to a good Earth. The Earth connection
should have a cross-sectional area sufficient enough to ensure a low
impedance, in order to attenuate RF interference.

Chapter 3 Power Supplies
There are three types of power supply available within the UAB system. The rack versions RUA1 and RUA2 are served
by a common power supply, which offers power to the 12 channels in the case of the RUA1 and 8 channels for the
RUA2. The Surface Mount versions are offered with mains an AC version or a low voltage DC version.
Section 1 - The Rack Version (RS1)
The RS1 supplies power to the channels within the rack via the common back plane, offering 220/240VAC at 50/60
Hz or 110VAC at 50/60 Hz. The 110/240 is selected by a switch on the rear of the power supply module. A green LED
on the front panel indicates when power is applied
A 5-Ampere protection fuse is fitted within the power input socket.
The maximum power rating for a full rack is 100 Watts.
Connection to the rack is made via a flying lead with a shrouded and earthed IEC mains connector
Note: Inputs are not intended to be connected to voltages above 50 VAC or 120Vdc
Tables 3.1 and 3.2 show details of the connections and voltages for the various supply rails.

A maximum power rating of 10 Watts is available, with this module.
The running current for each amplifier is between 250 and 480 milliamps dependant upon module configuration,
with a start up current of 3 Amps for 20 milliseconds. Earthing (or shield)- If the amplifier is not earthed elsewhere,

1. Connect the thermocouple to the UAB terminal as shown in Figure 4.6
Note: If the thermocouple has a floating input, connect terminal 1 to ground.
2. The external cold junction sensor is always connected between input terminals 4 and 6. If no external sensor is
used, link terminals 4 & 6.

UAFLC Fast Strain Gauge
The UAFLC offers a direct connection to most low level (foil) strain gauge sensors.
A 10-volt excitation is provided and it is monitored to compensate for any variation due to supply drift, load
regulation or voltage drop in the cable between the sensor and the UAFLC.
The maximum supply current is 150mA, which allows for the connection of 4 x 350 Ohm strain gauges.
Strain gauge sensitivity is preset via DIL switches to 0.5, 0.8, 1.0, 1.25, 1.5, 2.0, 2.5, 3.5, 5, 10, 20, 50, 100 and 200
mV/V. Select the next value higher than the strain gauge output maximum.
Note: It is important that the UAFLC is powered up with the strain gauge connected to the input as the A/D
performs an Autocal of its own on power up.

Fast Strain Gauge The (UAFLC) Module
Figure 4.9 UAFLC Module Figure 4.10 UAFLC Connections
Dual Input Modules
Provide two non-isolated inputs either 4 to 20mA or 0 to 10 volts (This should be specified at time of order) as:
•UADIA = 4/20mA
•UADIV = 0/10 volts
These inputs have independent scaling factors IPLA and IPHA for input 'A' and IPLB and IPHB for input 'B'.
The display can be selected from the list of 'A' and 'B' functions as follows, and can be selected under the mnemonic
'Ab'

A x B
A/B
A = process input, B = setpoint (SP1)
Scale factors can be applied to this function using a scale factor 'SF', a division factor 'DF' and a display offset 'OFFS'.
The analogue output, relays and printer take their value from the function selected at 'Ab’.

Chapter 5 Output Modules
Section 1 - General Description
Analogue outputs of 4 to 20mAmps and 0 to 10 volts are standard features and an integral part of the Universal
Amplifier pcb.
Further output modules are available offering alarm/control, printer and communications facilities. Analogue
outputs are fully scaleable, opto-isolated and digitally generated.
The analogue output signals are generated by the CPU from the displayed input variable, so that output signals are
normally related to displayed input values except where the PID function is selected. The 4 to 20 mA output is pre
calibrated to an accuracy of within 0.15% of the range. The 0-10V outputs are accurate to within 2% of the 4 to
20mA output.
Notes:
1. Maximum current load on voltage modules is 2mA
2. Maximum drive voltage available in current modules is 20V
The PID function is an option selectable within the standard software program and provides, where required an
analogue output so that outputs are related to the PID power levels and not the displayed input signal.
Note: In this mode the analogue output cannot be scaled.
A fast analogue output module (UAFAO) is available for use with the fast strain gauge (10msec) input (UAFLC),
where a fast capture facility is a requirement.
The digital output modules consist of two single pole change over relays with ON/OFF or PID control. If required,
latching outputs may be selected via the keypad, reset action being achieved by a contact closure or via the
communications module, where a program has been written via an appropriate protocol.
Set points and hysterisis are also set via the keypad or from a communications input.
Relay outputs may also be inverted via the keypad.
Relay operations are controlled by set point and hysterisis values, output inversion, time delays or by the PID time
proportioning output on set point 1.

Important Note 1: The output action mnemonic OA must be set to 32 when operating with this module.
Important Note 2: When changing the value of OA to, or from ’32; it is necessary to power the unit off and back on
again as a restart.
