Features:
- AI, 0–5 VDC, differential, 32 pts
- An analog input (AI) module includes three independent input channels
- Analog Input Modules 0-5 VDC Differential, DC Coupled, TMR TYPE
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 3700A Invensys Triconex Analog Input Module 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.
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.
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.
