HARDWARE DESCRIPTION
1 - 2 I-E96-424A
®
HARDWARE DESCRIPTION
A TDI is a single printed circuit board that attaches to a Field
Termination Panel (NFTP01) inside an INFI 90 cabinet. Two
screws and spacers secure the TDI in place. Up to sixteen indi-
vidual I/O signals can be connected to the TDI. The printed cir-
cuit board consists of:
1. Sixteen point configuration sockets (XU1 to XU16) to con-
figure each I/O signal.
2. Four terminal blocks (TB1 to TB4) that provide the physical
connection points for I/O signals.
3. A termination cable socket (P1) that connects the termina-
tion unit to its slave or master module.
4. I/O power (24 VDC, 125 VDC or 120 VAC) connection
points (E1, E2 and E3 common) for system powered configura-
tions.
5. Two on-board fuses (F1 and F2) to protect the E1/E2 power
supplies and field devices connected to the termination unit.
6. A termination unit configuration socket (XU17) to configure
TDI signal routing for some applications.
FEATURES
Versatile The design of the TDI allows it to be used with a variety of INFI
90 modules. It can be used to input digital or analog signals to
the INFI 90 system, or output digital or analog signals to field
devices. These signals provide control and monitoring capabili-
ties to the system.
Adaptable Sixteen individual I/O signals can be connected to the TDI.
These signals can be configured according to the process
requirements. Dipshunts on the termination unit configure
each I/O channel. Each channel can be configured as a system
powered signal or field powered signal.
Reliable The TDI is a passive assembly with no active components
mounted on its circuit board; it does not require power to oper-
ate. This makes the termination unit less susceptible to failure.
System Protection Fused power inputs protect INFI 90 module circuitry and pro-
cess field devices.
Minor Maintenance Other than routine maintenance as defined in Section 3, the
TDI does not have any special maintenance requirements.

SECTION 2 - INSTALLATION
INTRODUCTION
This section explains the procedures to install and configure a
Digital I/O Termination Unit (TDI). DO NOT proceed with
installation until you read and understand the steps explained.
SPECIAL HANDLING
The TDI does not use electrostatic sensitive devices. However,
during installation of the TDI you may be required to remove a
module from the INFI 90 module mounting unit. Most master/
slave modules in the INFI 90 system use electrostatic sensitive
devices, and require special handling.
NOTE: Always use Bailey's Field Static Kit (P/N 1948385A2 - con-
sists of wrist strap, ground cord assembly, alligator clip) when work-
ing with modules. The kit is designed to connect a technician and
the static dissipative work surface to the same ground point to pre-
vent damage to the modules by electrostatic discharge.
UNPACKING AND INSPECTION
1. Unpack and examine the termination unit immediately to
verify it has not been damaged in transit.
2. Notify the nearest Bailey Controls sales office of any such
damage.
3. File a claim for any damage with the transportation com-
pany that handled the shipment.
4. Use the original packing material and container to store the
hardware.
5. Store the hardware in an environment of good air quality,
free from temperature and moisture extremes.
SETUP/PHYSICAL INSTALLATION
Several steps must be performed to configure the TDI for its
intended application. After securing the termination unit to a
field termination panel, dipshunts must be configured and
installed, fuses inserted, external connections made and, if
applicable, system power connected to the TDI.
Figure 2-1 shows the TDI and the location of the dipshunt
sockets (XU1 to XU17), terminal blocks (TB1 to TB4), cable
connector (P1), system power connectors (E1, E2 and E3) and
fuses (F1 and F2).

taking care not to bend the dipshunt pins.
NOTE: Make sure that pin 1 of the dipshunt corresponds to pin 1 of
the socket when installing.
5. Repeat steps two through four until all required sockets are
configured.
Installing Fuses
On-board fuses provide protection for the system power sup-
plies and field devices. Figure 2-1 shows the location of the
fuses on the TDI. Fuse 1 (F1) is for the E1 power supply; fuse 2
(F2) is for the E2 power supply.
Determine the I/O voltage requirements for your application
and insert the appropriate fuse in the circuit board fuse hold-
ers. If a 24 VDC I/O voltage is required from E1 or E2, use a
three amp fuse (P/N 194776A13001). If a 125 VDC or 120 VAC
I/O voltage is required from E1 or E2, use a 0.25 amp fuse (P/
N 194776A12500).
WIRING CONNECTIONS AND CABLING
Terminal blocks (TB1 through TB4) on the TDI connect field
wiring to the INFI 90 system. A termination cable connects the
termination unit to its master/slave module to route I/O sig-
nals.
Cable Connections
Install the termination cable (NKTU01) after the TDI is properly
mounted on the field termination panel. Figure 2-5 shows the
cable connections. To install the termination unit cable:
1. Insert the hooded end of the cable into the module mount-
ing unit backplane slot assigned to the master/slave module.
The cable should latch securely in place. P3 of the master/
slave module in the module mounting unit connects to this end
of the cable.
2. Insert the socket connector end of the cable in the P1 con-
nector of the TDI. Figure 2-1 shows the location of P1 on the
TDI circuit board.

Terminal Block Wiring
The polarity and use of each terminal depends on the configu-
ration of the TDI. Refer to Figure 2-1 for general I/O point ter-
minal block assignments. Refer to the appendices for specific
application I/O point terminal block assignments and point
wiring polarity. A 12 AWG to 22 AWG wire should be used for
field wiring.
NOTES:
1. Proper polarity wiring is required for DC signals.
2. There are only 30 pins on the master/slave module P3 connec-
tor; the termination unit can handle 16 I/O points. When using points
7 and 8 of each group, the positive (+) side of these points share a
pin (A7 - A8 and B7 - B8). Refer to Table 2-1.
Each installation is unique, presenting a special set of require-
ments and operating conditions. Refer to the Site Planning,
Preparation and Equipment Installation Product Instruc-
tion, I-E93-900-5 for analog and digital I/O line wiring
requirements. It provides a general description of wiring rec-
ommendations for process I/O signals.
System Power Connections
Some I/O configurations require system power (24 VDC, 125
VDC or 120 VAC). Three terminals (E1, E2 and E3 common)

CAUTION
We strongly recommend that you turn the cabinet power off
before doing any termination unit wiring. Failure to do so could
result in equipment damage. Do not apply power until you ver-
ify all wire connections.
ATTENTION
Il est fortement recommande de debrancher l'alimentation elec-
trique du cabinet avant d'effectuer toute connexion aux cartes
de raccordement du chassis. Des dommages aux equipements
pourraient survenir dans le cas contraire. Ne pas rebrancher
l'alimentation avant que toutes les connexions aient ete veri-
fiees.

provide connection points for system power wiring and ground.
See Figure 2-1 for the location of these terminals.
System power connects to the termination unit through faston
connectors E1 and E2, and it is distributed to the configura-
tion sockets through the fuses. Any combination of power can
be connected to these fastons depending on the application.
However, this requires careful system analysis to ensure cir-
cuit board trace amperage capacity is not exceeded. The TDI
can handle two amps continuous through a single trace. Sys-
tem ground connects through faston connector E3.
Use 12 to 14 AWG wire to connect power from the I/O power
panel or modular power supplies to the TDI terminals. Refer to
the I/O Power Panel Product Instruction, I-E93-909-3 or
Modular Power System Product Instruction, I-E96-506 for
further details.
PRE-OPERATING ADJUSTMENTS
The TDI does not require any pre-operating adjustments.
P1 PIN OUT
Refer to Figure 2-3 for connections between P1 pins and point
configuration sockets XU1 through XU4, XU7, XU8 and XU11
through XU16. For these sockets, all even numbered P1 pins in
Table 2-1 connect to pins 1, 2, 3 and 4 of the sockets; all odd
numbered P1 pins connect to pins 5 and 6 of the sockets.
Refer to Figure 2-4 for connection between P1 pins, the termi-
nation unit configuration socket and point configuration sock-
ets XU5, XU6, XU9 and XU10.
