Figure 4 I/O Companion Slot Cable Type TC-204
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 external terminals 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 left as a ‘flying lead’ enabling the cable
to be terminated as required, e.g. connected to conditioned field terminals.
The flying leads are sleeved with identity ferrules marked CH1, CH2, CH3 etc. for channel
terminations or 0 V for group reference terminations.
The multi-core cable is stripped back 2.0 m at both ends, 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 the chassis 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.
