This type of cable, and the modules/field termination assemblies it is used with, is shown in Figure 11
below.
Figure 11 I/O Companion Slot Cable Type TC-211
This type of Trusted TM I/O Companion Slot Cable is designed for use with analogue or digital input
modules and is suitable for connecting input signals from an internal 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 0V 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 0V supply. Commoning of
the reference is obtained by a connection to this field supply.
The multi-core is stripped back 1.5m at both ends, then shrouded in nylon Rilgain sheathing. The ends
of the sheathing are heated or fitted with over sleeving to prevent fraying.
At the chassis end, a sheathed braid allows the connector hood to be wired to safety earth. At the
remote end, the multicore screen drain is wired to a green wire to allow connection to screen earth.
