Features:
- 40 Triple Modular Redundant (TMR) input channels per module.
- Comprehensive, automatic diagnostics and self-test.
- Selectable line monitoring per channel to detect open circuit and short circuit field wiringfaults.
- 2500Vdc opto/galvanic isolation barrier.
- On-board Sequence of Events (SOE) reporting with 1ms resolution.
- Front panel module status LEDs indicate module health andoperational mode
- Front panel input status LEDs for each channel indicate input statusand field wiring faults.
Each field input is triplicated and the input voltage is measured using asigma-delta input circuit. The resulting field voltage measurement iscompared to user configurable threshold voltages to determine the reportedfield input state. When a line-monitoring device is installed at the field switch,the module can detect open and short circuit field cables. Line monitoringfunctions are independently configured for each input channel. Thetriplicated voltage measurement, coupled with onboard diagnostic testing,provides comprehensive fault detection and tolerance.
The module provides onboard Sequence of Events (SOE) reporting with aresolution of 1 ms. A change of state triggers an SOE entry. States aredetermined by voltage thresholds that can be configured on a per channelbasis.
The T8403 ICS Triplex INPUT MODULE may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The Trusted TMR 24 Vdc Digital Input Module is a member of the Trustedrange of Input/Output (I/O) modules. All Trusted I/O Modules share commonfunctionality and form. At the most general level, all I/O Modules interface tothe Inter-Module Bus (IMB) which provides power and allows communicationwith the Trusted TMR Processor. In addition, all Modules have a field.
The Input Module automatically measures the field input voltage, comparesthe value to the configurable thresholds, and determines the state of the fieldinput. An event occurs when the input transitions from one state to another.When an input changes state, the onboard real-time clock value is recorded.When the TMR Processor next reads data from the Input Module, the inputstate and real-time clock values are retrieved.
- Emergency Shutdown Systems :Monitors safety sensors & triggers shutdowns in hazardous conditions.
- Fire and Gas Monitoring :Processes fire & gas sensor signals to activate suppression or alarms.
- Burner Management Systems :Manages safety interlocks for industrial boilers and furnaces.
- Critical Process Control:Monitors discrete field devices to prevent false-off signals & downtime.
- Nuclear Power Safety Control:High-integrity monitoring & control for nuclear facilities.

While both modules share the same 40-channel Triple Modular Redundant (TMR) architecture and SIL 3 certification, they are distinguished by their protective coatings.
T8403 (Standard Version): Designed for standard industrial environments. It lacks specialized coating and is suitable for clean, climate-controlled control rooms.
T8403C (Conformal Coated): Includes conformal coating on the internal circuit boards.
