Module T8442

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.
The 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.
