It is a high-reliability relay output module and a core component of TRICONEX’s Tricon and Trident Safety Instrumented System (SIS) platforms. It is mainly used in safety-critical industrial automation systems as a key interface between safety controllers and on-site equipment requiring high-power drive, such as emergency shutdown valves, fire protection system actuators, and isolation relays.

It adopts a Triple Modular Redundancy (TMR) architecture. Each output signal is processed through three independent channels, using a 2-out-of-3 voting mechanism to eliminate single points of failure. This ensures continuous operation even if one channel fails—a feature crucial for applications such as emergency shutdown systems on offshore oil platforms, where downtime could lead to environmental disasters or significant economic losses.
