Features:

  • TMR Analog Input Modules
  • An analog input (AI) module includes three independent input channels
  • TRICON Isolated Analog Input AI, 0–5/0–10 VDC, isolated, 16 pts.
An analog input (AI) module includes three independent input channels. Each input channel receives variable voltage signals from each point, converts them to digital values, and transmits the values to the three main processor modules on demand. In TMR mode, one value is then selected using a midvalue selection algorithm to ensure correct data for every scan.

The analog input module requires a separate external termination panel (ETP) with a cable interface to the Tricon backplane. Each module is mechanically keyed for proper installation in a Tricon chassis.

The 3703E Invensys Triconex Analog Input Modules may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
Sensing of each input point is performed in a manner that prevents a single failure on one channel from affecting another channel. Each analog input module sustains complete, ongoing diagnostics for each channel. Failure of any diagnostic on any channel activates the Fault indicator for the module, which in turn activates the chassis alarm signal. The module’s Fault indicator merely reports a channel fault, not a module failure—the module can operate properly with as many as two faulty channels.

Ask our team:

  • What is the functional role of the 3703E in the Triconex safety instrumented system architecture?
    As a high-integrity analog input module, the 3703E acquires field analog signals and transmits processed and verified process data to the Tricon safety controller for the execution of deterministic safety logic.
  • How does the 3703E achieve the accuracy and signal fidelity of industrial analog inputs?
    The 3703E integrates advanced signal conditioning, filtering, and diagnostic monitoring functions to ensure high-precision conversion and stable interpretation of process measurement results.
  • Why is the 3703E suitable for SIL-level and mission-critical environments?
    The 3703E is designed to meet stringent functional safety requirements, providing comprehensive diagnostic and fault detection capabilities, and can be integrated into triple modular redundancy (TMR) architectures.
  • What types of field signals can the 3703E typically handle?
    The 3703E module is designed to interface with industry-standard analog signals, such as the 4–20 mA process loops commonly used for pressure, temperature, flow, and level instruments.
  • What redundancy mechanisms does the 3703E module have?
    The 3703E operates within the Triconex TMR framework, supporting three-path signal verification to maintain system availability and eliminate single points of failure.
