Product Summary
The ICS Triplex T8153 Communications Interface Adapter grants external systems direct access to a Trusted TMR Processor. This unit connects easily to the rear of a Controller Chassis. It enables critical features like IRIG-B time synchronization and MODBUS Master functionality. Engineers use this adapter to create reliable communication links for their DCS.
Theme A: Product Procurement & Buyer Guide
Procurement managers require a reliable link for their safety systems. The T8153 solves this need by providing a direct interface to the TMR Processor. It allows easy access for external DCS and other critical links. This adapter eliminates the need for complex custom cabling solutions. Your team can integrate it quickly and confidently.
This specific model supports two RS422/485 configurable ports for 2 or 4 wire connections. It also includes one dedicated RS422/485 2-wire connection. These ports provide the flexibility needed for various field devices. The adapter also offers fault/fail connections for both Active and Standby Processors. This feature is crucial for maintaining system integrity during a failure.

The unit also provides processor diagnostics and PSU shutdown monitor connections. These connections allow maintenance teams to perform proactive system checks. You can monitor the health of your processor power supply directly. This capability significantly reduces unplanned downtime in your facility. It provides clear data for predictive maintenance scheduling.
An optional feature enables the reception of IRIG-B122 and IRIG-B002 time signals. This synchronization is vital for time-stamping events across the plant. Another option enables the Trusted System to become a MODBUS Master. This allows the system to poll data from remote MODBUS slave devices. These options extend the utility of your existing Trusted infrastructure.
For ordering, you need the exact model T8153 from the ICS Triplex catalog. This unit originates from the United States and carries Ordinary, HazLoc, ATEX, and IECEx certifications. Ensure your procurement team specifies the correct model for your environment. This adapter is a direct replacement for the T812x series. It provides enhanced functionality for modern control systems.
Theme B: Step-by-Step User & Installation Guide

Begin the installation by locating the Trusted TMR Processor position in your Controller Chassis. The T8153 adapter is designed to connect directly to the chassis rear. First, align the adapter’s two 48-way DIN41612 E-type connectors with the processor slots. One connector attaches to the Active Processor and one to the Standby Processor. Ensure the alignment is precise to avoid damaging the pins.
Next, clip the metal enclosure of the adapter onto the chassis connector. You will hear a click when it is securely fastened. The release buttons allow for easy disconnection if needed later. This mounting method is robust and requires no tools for installation. It secures the adapter firmly in a high-vibration industrial environment.
Now, connect your communication cables to the appropriate ports. Use Port 1 for RS422/RS485 2-wire connections. Use Ports 2 and 3 for RS422/RS485 2 or 4-wire configurations. Verify the wiring configuration matches your DCS or remote system requirements. Incorrect wiring can cause communication faults or hardware damage.
Finally, you must establish an earth connection for safety. The adapter provides a dedicated earth point on the PCB. Connect this point to the Chassis earth of the Processor and the rack earth. This equipotential bonding is a critical safety and ESD requirement. It protects the sensitive electronics from electrostatic discharge and ground loops.
