Features:
- TMR Digital Input Modules
- Digital Input, 24 VDC, Commoned
- 24 VAC/VDC, commoned in groups of 8, TMR with self-test
Each TMR digital input (DI) module has three isolated input channels which independently process all data input to the module. A microprocessor on each channel scans each input point, compiles data, and transmits it to the main processors upon demand. Then input data is voted at the main processors just prior to processing to ensure the highest integrity.
All critical signal paths are 100 percent triplicated for guaranteed safety and maximum availability. Each channel conditions signals independently and provides optical isolation between the field and the Tricon.
The 3503E Invensys Triconex TMR Digital Input 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 input modules support hot-spare capability, and require a separate external termination panel (ETP) with a cable interface to the Tricon backplane. Each module is mechanically keyed to prevent improper installation in a configured chassis.
Emergency Shutdown (ESD) System: Serves as the last line of defense, safely shutting off process valves in hazardous chemical infrastructure.
Fire and Gas (F&G) System: Quickly verifies detector inputs and initiates local mitigation procedures.
Steam Turbine and Compressor Control System: Controls speed limits and overspeed trip parameters for large rotating equipment.
Boiler Management System (BMS): Ensures safe ignition, operation, and fuel isolation of utility boiler units.
