WARNINGS AND CAUTIONS
WARNING: EXPLOSION RISK
Do not connect or disconnect equipment while the circuit is live or unless the area is
known to be free of ignitable concentrations or equivalent
AVERTISSEMENT - RISQUE D’EXPLOSION
Ne pas connecter ou déconnecter l’équipement alors qu’il est sous tension, sauf si
l’environnement est exempt de concentrations inflammables ou équivalente
MAINTENANCE
Maintenance must be carried out only by qualified personnel. Failure to follow these
instructions may result in personal injury.
CAUTION: RADIO FREQUENCY INTERFERENCE
Most electronic equipment is influenced by Radio Frequency Interference. Caution
should be exercised with regard to the use of portable communications equipment

1. Description
Figure 1 T8312 Photo
The Trusted Expander Interface Adapter Unit T8312 comprises four, or seven 12-pin ODU
connectors (dependent on type of Unit), a printed circuit board (PCB), a 96-way C type
connector which plugs into a double 96-way connector assembly designed to be connected
to the Trusted Expander Interface Modules resident in the Controller Chassis. The Unit is
contained within a metal enclosure and is designed to be clipped onto the Controller Chassis
rear connectors. A release button is provided to enable the Unit to be disconnected.

Trusted TMR Expander Interface Adapter Unit 1. Description
Rockwell Automation Publication PD_T8312 Issue 12 7
Chassis connections for both Units are organised as below.
1 connects to the first Expander Chassis (which has its three ID switches configured
to address 2).
2 connects to the second Expander Chassis (which has its three ID switches
configured to address 3).
…
8 connects to the eighth Expander Chassis (which has its three ID switches
configured to address 8).
The addresses are set 2,3,4…8 to fit logically with the Processor Chassis virtual address of 1.
If more than eight Chassis are needed, a second Expander Interface is required. The address
switches on these Chassis are also set 2,3,4…8 but the virtual addresses (as seen by the
application and diagnostics) are 9,10,11…15 as set in the System.INI configuration.
Refer to PD-8300 for further explanations on ID settings.
