TRICONEX 3401 Digital Output Module

Product Description:
The TRICONEX 3401 Digital Output Module is a 16-channel triple modular redundancy (TMR) output module designed for safety instrumented systems (SIS). It is used to reliably control actuators, interlocks, emergency shutdown devices, and other discrete processes in critical industrial environments such as oil, gas, chemicals, and power. The module uses an advanced Quad Voter circuit for two-out-of-three logic voting, ensuring system operation even if one channel fails. Real-time diagnostics and hot-swap capability are built in for maximum safety, availability, and process continuity.​
