I/O Companion Slot Cable Type TC-205
This type of cable, and the modules/field termination assemblies it is used with, is shown in
Figure 5 below.
Figure 5 I/O Companion Slot Cable Type TC-205
This type of Trusted I/O Companion Slot Cable is designed for use with digital 24 V/120 Vdc
or analogue output modules and is suitable for connecting output signals from the module
to an internal FTA.
Three multi-core cables are used for this application. The chassis end of multi-core 1 is fitted
with two 96-way type ‘C’ connectors housed in a double-width hood. The non-chassis end of
multi-core 1 is fitted with a 96-way type ‘R’ connector housed in a single-width hood
enabling connection to an FTA. The non-chassis end of multi-core 2 is fitted with a 5-way
BLZF 3.5 series connector enabling the cable to be terminated at a T8290 Output Power
Distribution Unit. This cable is used for field power return. The non-chassis end of multi-core
3 is fitted with a 6-way AMP plug used to connect power to the field from a T8290 or T8297
and is made up of five individual 2.5 mm wires contained within Rilgain sleeving.
The 0 V connection at the chassis end allows a module reference so that it can measure its
output voltage, this must be connected to the field 0 Volts.
The FTA contains isolated power group field 0 Volts which connect to field 0 V supply.
Commoning of the reference is obtained by a connection between this field supply and the
T8290 Output Power Distribution Unit (TB1 pins 1 and 2).
