Figure 3 I/O Companion Slot Cable Type TC-203
This type of Trusted I/O Companion Slot Cable is designed for use with analogue or digital
input modules and is suitable for connecting input signals from a remote FTA to the module.
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.
The multi-core cable is stripped back 2.0 m at the chassis end and 1.5 m at the FTA end.
Both ends are then shrouded in nylon Rilgain sheathing. The Rilgain sheathing is cut with a
heat gun to help prevent fraying. Joints between the Rilgain sheathing and the multi-core
outer sheath are taped over with 25 mm PVC insulating tape and then covered with
heatshrink sleeving.
At both the chassis and remote end, a sheathed braid allows the connector hood to be
wired to safety earth. At the remote end, the multi-core screen drain is wired to a green
wire to allow connection to screen earth.
