9. I/O SmartSlot Cable Type TC-509
This type of cable, and the modules/versatile field termination assemblies it is used with, is shown in
Figure 9 below.
Figure 9 I/O SmartSlot Cable Type TC-509
This type of Trusted TM I/O SmartSlot Cable is designed for use with digital 24V/120V dc and analogue
output modules and is suitable for connecting output signals from the module to an internal VFTA. For
the T8448 and T8449, it is recommended to use the T8842 VFTA. PD-T8842 describes the possible
circuits that may be configured for this VFTA.
Two multi-core cables are required for this application. The chassis end of the multi-core 1 is fitted
with a 96-way type ‘C’ connector housed in a single-width hood (TC-500). The other end of multi-core
1 is fitted with five 10-way Weidmuller BLZF 3.5 series connectors enabling the cable to be terminated
at a VFTA. 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. This cable is made up of five individual 2.5mm wires contained
within Rilgain sleeving. For analogue output or low current digital output modules using this cable, the
T8297 is recommended.
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.
Multi-core 1 is stripped back 1.5m at both ends, then shrouded in nylon Rilgain sheathing. Multi-core 2
is 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.
