Hardware Features and Design

The T8153 connects to the Trusted TMR Processor via two 48-way DIN41612 E-type connectors (SK1). One connector links to the Active Processor. The other connects to the Standby Processor. The adapter includes a PCB with all communication ports and IRIG-B connectors. A metal enclosure protects the internal components. Release buttons allow easy disconnection from the chassis. An earth point connects the Processor chassis ground to the adapter shell.

Safety and Installation Requirements

Proper equipotential bonding is critical for safe operation. This bonding prevents electrostatic discharge (ESD) damage. Always connect the earth point before powering up the system. The adapter is designed for hazardous location use (ATEX/IECEx certified). Follow all local safety codes during installation.

Installation Guide

Turn off all power to the Trusted Controller Chassis.

Align the T8153 adapter with the rear connectors of the processor slot.

Press firmly until the adapter clicks into place.

Connect the earth point to the chassis ground.

Attach communication cables to the required RS422/485 ports.

For IRIG-B time sync, connect signals to the dedicated input.

To enable MODBUS Master, configure the option via system software.
