I/O Companion Slot Cable Type TC-215
This type of cable, and the modules/field termination assemblies it is used with, is shown in
Figure 13 below.
Figure 13 I/O Companion Slot Cable Type TC-215
This type of Trusted I/O Companion Slot Cable is designed for use with 24 V or 120 Vdc
digital output modules and is suitable for connecting output signals from the module to an
internal FTA. Power connections are integral with this type of cable.
The chassis end of the multi-core cable is fitted with two 96-way type ‘C’ connectors housed
in a double-width hood. The other end of the cable is fitted with a 96-way type ‘R’
connector housed in a single-width hood enabling the cable to be connected to an FTA.
Using this cable, the field power is connected at the FTA, which has indicators for each
power group which are voltage sensitive. For this reason, the T8850 FTA should be used
with the T8451 and the T8870 with the T8471.
The 0 V connection at the FTA 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 to this field supply.
