TRICONEX 3806E Analog Output Module

Product Description

• The Triconex 3806E is a triple-modular redundant (TMR) analog output module used in Tricon safety and critical control systems (v9–v10).

• It converts digital control signals from the Tricon controller into analog current or voltage outputs for process control across turbomachinery, valves, actuators, etc.

• Designed for high-reliability and safety-critical applications, it features continuous diagnostics, common return, DC coupling, and redundant power supply inputs.
