7. I/O SmartSlot Cable Type TC-507
This type of cable, and the modules/field termination assemblies it is used with, is shown in Figure 7
below.
Figure 7 I/O SmartSlot Cable Type TC-507
This type of Trusted TM I/O SmartSlot 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 an external FTA.
Three multi-core cables are used for this application. The chassis end of the multi-core cable is fitted
with a 96-way type ‘C’ connector housed in a single-width hood (TC-500). The non-chassis end of
multi-core 1 is fitted with a 96-way type ‘R’ connector housed in a single-width hood enabling
connection to an FTA. The non-chassis end of multi-core 2 is fitted with a 5-way Weidmuller BLZF 3.5
series connector enabling the cable to be terminated at a T8290 Output Power Distribution Unit. This
cable is used for field power return. The non-chassis end of multi-core 3 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 0V connection at the chassis end allows a module reference so that it can measure its output
voltage, this must be connected to the field 0 Volts.
The FTA contains isolated power group field 0 Volts which connect to field 0V supply. Commoning of
the reference is obtained by a connection between this field supply and the T8290 Output power
distribution unit (TB1 pins 1 and 2).
Multi-core 1 is stripped back 1.5m at both ends. Multi-cores 1, 2 and 3 are shrouded in nylon Rilgain
sheathing. The ends of the sheathing are heated, or over sleeved as required to prevent fraying.
At both the chassis and remote 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.
