Module T8442
Issue 8 Apr 10 PD-T8442 20
2.3. Field Interface Connector
The field interface on the module is via a 96 way DIN41612 C type connector. These mates with a TC-
801 cable assembly. The cable assembly must be pre-installed in a Trusted
TM
chassis I/O slot that has
been configured for use with T8442 module.
T
he field connector is made up of three columns of 32 pins. The functions of these pins are detailed in
Table 2, Table 3 and Table 4. Note that the table below is provided for reference only, since the T8442
module must always be connected to a T8446 SIFTA for speed inputs, and one or more T8891
SOFTA units for outputs. Direct connection of the field interface connector to field devices is not
supported.
