Product Description:
The 7400165-380 REV A1 is a high-density External Termination Panel (ETP) for the Triconex Triple Modular Redundant (TMR) safety system. It provides the interface between field sensors/actuators and the controller’s I/O modules, ensuring reliable signal transmission in Safety Instrumented Functions (SIF). With 121 screw-type terminals, it supports complex signal routing for Emergency Shutdown (ESD) and Burner Management Systems (BMS), while maintaining signal integrity in high-vibration and electromagnetically noisy environments.
