Products Description
TRICONEX EPI3382 32-Channel Analog Input Module
TRICONEX EPI3382 (also known as 3382) is a 32-channel high-density analog input module for Tricon triple modular redundant safety instrumented system. It acquires 0-10V DC analog signals from field transmitters and sensors, with TMR 2oo3 voting architecture to eliminate single point failure for safety loop.
This module supports continuous per-channel self-diagnosis to detect wire break, short circuit and hardware drift. It features hot-swap function for online replacement without system shutdown, certified to IEC 61508 SIL3. It is end-of-life, supplied as surplus or refurbished spare parts for legacy Tricon SIS rack maintenance.
