Product Detail

Original ICS Triplex P8431 TMR analog input module for Plantguard safety instrument system, SIL3 certified spare part.

Product Overview

P8431 is ICS TRIPLEX Plantguard series 40‑channel TMR analog input safety module. It collects 4‑20mA, voltage and thermocouple field sensor signals, adopts triple‑modular‑redundant hardware voting architecture to realize single‑fault tolerance, used for ESD, fire‑gas and process interlock safety logic. Built‑in 1ms resolution SOE event sequence recording function, supports per‑channel line fault detection for open‑circuit and short‑circuit diagnosis. SmartSlot rack plug‑in structure, supports hot‑swap maintenance. Widely used as maintenance spare part for oil‑gas, petrochemical and power‑plant safety control cabinets.
