Features:
- TMR Digital Output Modules
- Opto-Isolated, Non-commoned
- Triple-Modular Redundant (TMR) architecture
The TMR Digital Output (DO) module receives output signals from the main processor, each channel receives three signals. Then, each group of three signals is voted on by a special four-way redundant output circuit on the module. This circuit generates a voted output signal, and transmits it to the field terminal.
Four redundant voting circuits provide multiple redundancies for all critical signal paths, ensuring safety and maximum availability. Each TMR digital output module is equipped with a voltage loopback circuit that independently verifies the operation of each output switch and identifies potential faults.
The 3604E Invensys triconex TMR Digital Output Modules may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
All TMR digital output modules support hot standby and require a separate external terminal block (ETP) that connects to the Tricon backplane via a cable interface. Each module is mechanically designed to prevent incorrect installation within the configured chassis. The digital outputs are designed to power field devices; therefore, each output point on the field terminal block must be connected to a field power supply.
Emergency Shutdown (ESD): Drives final control elements such as solenoid valves and trip relays to isolate process units in the event of a hazardous incident.
Boiler Management System (BMS): Controls the safety sequence, fuel valve isolation, and purge/ignition interlocks of industrial boilers and furnaces.
Fire and Gas (F&G) System: Drives alarms, warning lights, fire dampers, and deluge valves based on safety logic.
High Integrity Pressure Protection System (HIPPS): Quickly and deterministically isolates high-pressure sources to protect downstream equipment.
Process Equipment Interlocks: Manages interlocks for motors, contactors, and critical equipment.
