This type of cable, and the modules it is used with, is shown in Figure 8 below.
Figure 8 I/O Companion Slot Cable Type TC-208
This type of Trusted TM I/O Companion Slot Cable is designed for use with digital 24V/120V dc or
analogue output modules and is suitable for connecting output signals from the module to external
terminals.
Two multi-core cables are required for this application. The chassis end of the multi-core 1 is fitted
with two 96-way type ‘C’ connectors housed in a double-width hood. The other end of multi-core 1 is
left as a ‘flying lead’ enabling the cable to be terminated as required, e.g. connected to conditioned field
terminals. The non-chassis end of multi-core 2 is fitted with a 6-way Amp plug used to connect power
to the field from a T8290 or T8297 and is made up of five individual 2.5mm wires contained within
Rilgain sleeving.
The flying leads are sleeved with identity ferrules marked CH1, CH2, CH3 etc. for channel terminations
or V FIELD RTNGRP1 to V FIELD RTNGRP5 for group reference terminations.
The 0V connections at the flying leads end allows a module reference so that it can measure its output
voltage, these must be connected to the field 0 Volts.
The flying lead multi-core 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.
Multi-core 1 is stripped back 1.5m at both ends. Multi-cores 1 and 2 are shrouded in nylon Rilgain
sheathing. The ends of the sheathing are heated, or over sleeved as required 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.
