This type of cable, and the modules/versatile field termination assemblies it is used with, is
shown in Figure 12 below.
Figure 12 I/O Companion Slot Cable Type TC-212
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 an external VFTA 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 multi-core is fitted with one 7-way and five 10-
way BLZF 3.5 series connectors enabling the cable to be terminated at a VFTA.
The 0 V connection at the VFTA end allows a module reference so that it can measure its
output voltage, this must be connected to the field 0 Volts.
The VFTA 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.
The multi-core is stripped back 1.5 m at both ends, then shrouded in nylon Rilgain
sheathing. The ends of the sheathing are heated or fitted with over sleeving to help prevent
fraying.
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.
