This type of cable, and the modules it is used with, is shown in Figure 17 below.
Figure 17 I/O SmartSlot Cable Type TC-521
This type of Trusted TM I/O SmartSlot Slot Cable is designed for use with the 8472 120V ac digital
output module only and is suitable for connecting output signals from the module to an internal 8871
FTA. Power connections are integral with this type of cable.
The chassis end of the multi-core cable is fitted with a 32-way type ‘D’ connector housed in a
single-width hood (TC-500). The other end of the cable is fitted with two 8-way and two 5-way
Weidmuller BLZF 5 series connectors enabling the cable to be terminated at an 8871 FTA. Both ends
are fitted with screw retention. The two 5-way connectors carry AC field power on three of the
terminals, which is supplied to the FTA via screw terminals. Each connector powers one group of eight
terminals. The AC power cables may also be stripped out of the multicore sheath and terminated at an
AC marshalling panel elsewhere.
The multi-core cable 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.
