ICS Triplex / Rockwell Automation T8123 IRIG-B and Modbus Processor Interface Adapter
A rear-mounted Trusted processor adapter that exposes serial communications, processor status connections and IRIG-B timing interfaces.
Product Identification
Trusted T8123 belongs to the T812x processor interface adapter family and connects directly behind the processor position in a T8100 controller chassis.
It provides communication access between active and standby Trusted processors and external systems, while also routing processor fault/fail, PSU shutdown-monitor and IRIG-B connections.
The T8123 identity is retained with the adapter series, rear-chassis connector position, serial-port wiring and timing-source record.

FAQ
Q01
Where is T8123 installed?
+
It clips to the appropriate connector at the rear of a Trusted T8100 controller chassis processor position.
Q02
Which communication wiring should be recorded for T8123?
+
Document Port 1 two-wire RS-422/485, Ports 2 and 3 two- or four-wire use, baud and protocol settings, shields and remote endpoints.
Q03
Does T8123 provide IRIG-B connections?
+
Yes. The adapter family provides options for IRIG-B122 and IRIG-B002 time-synchronization inputs.
Q04
What distinguishes a controlled T8123 spare enquiry?
+
Include the complete adapter label and series, both processor models, chassis identity, serial-port allocation, IRIG-B source and connector photographs.
Q05
How should T8123 be tested after service?
+
Verify processor status wiring, every used serial link, timing lock and the configured peer or Modbus Master function without disturbing the approved safety application.
