2.5. Trusted module polarisation / keying

Due to the high voltages used by the T8472 AC DO Module it differs from other I/O Modules. The
T8472 AC DO Module Field Connector is a 32 way DIN 41612 Type ‘d’. (Contact spacing on the type
‘d’ is 0.2 inches and a larger contact is used.)

Therefore the T8472 AC DO Module has a specific unique set of Field Cables, TC-221 or TC-521.
Refer to product descriptions PD-TC200 and PD-TC500 for further information. Other I/O Modules use
the 96 way DIN 41612 Type ‘c’ as their Field Connector, note however a type ‘c; connector will in fact
mate to a type ‘d’ connector.

For this reason Modules may be ‘Keyed’ to prevent insertion into the wrong connector within a chassis.
The polarisation comprises two parts. The module has key holes and the associated chassis / field
cable connectors have key pegs. Holes may be plugged with small plastic ‘bungs’ and the
corresponding connector pegs removed in a designated pattern to set the Modules Key Code.

Each module type will be keyed during manufacture. The organisation responsible for the integration of
the Trusted system must key the cable by removing the keying pieces from the cable so that they
correspond with the bungs fitted to the associated module prior to fitting.
