Description
Product Overview
Triconex 3000520-390 is a field termination and safety interface module for Tricon TMR Safety Instrumented System (SIS), under Schneider Electric Triconex brand. It provides screw terminal blocks for safe wiring termination between Triconex I/O modules and field sensors / solenoid actuators. This unit implements signal conditioning and galvanic isolation, protecting the TMR safety logic solver from field surge interference. Widely deployed in oil & gas, petrochemical and power generation safety shutdown systems. It is a critical spare for maintenance and retrofit of Tricon SIS racks.
