An analog input (AI) module includesthree independent input channels. Eachinput channel receives variable voltagesignals from each point, converts themto digital values, and transmits thevalues to the three main processormodules on demand. In TMR mode,one value is then selected using a midvalue selection algorithm to ensurecorrect data for every scan.

Sensing of each input point isperformed in a manner that prevents asingle failure on one channel from affecting another channel. Each analoginput module sustains complete,ongoing diagnostics for each channel.Failure of any diagnostic on anychannel activates the Fault indicator forthe module, which in turn activates thechassis alarm signal. The module’sFault indicator merely reports a channelfault, not a module failure—the modulecan operate properly with as many astwo faulty channels.

The 3703E TRICONEX Analog Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Verify Chassis Space: Ensure you have an open slot in a Tricon Main Chassis or Expansion Chassis.
Confirm Mechanical Keying: The 3703E module features integrated mechanical keys. These prevent insertion into a slot intended for a different module type.
Handle with Care: Adhere to ESD precautions and handling restrictions. Gently slide the card completely into the guide rails until it seats firmly into the backplane connector.
Lock the Module: Secure any hand-operated fasteners or retention screws to the specified torque values.
