TRICONEX EPI3382 High-Performance EPI Communication Gateway Module for Tricon TMR Safety Controller

Product Description

EPI3382 is a dedicated external protocol communication module for Tricon/Tricon2 triple redundant safety systems, acting as data bridge between Triconex safety controllers and external 

DCS, SCADA, HMI and historical databasesCSDN博.... Equipped with dual independent Ethernet ports, it supports Modbus TCP and multiple custom TCP/UDP protocols, 

undertakes protocol conversion and data buffering to reduce main CPU load. Adopts full TMR synchronization design, supports redundant dual-module hot standby seamless switching, 

isolated network circuit prevents external network interference from affecting safety logic. Widely used in petrochemical ESD, fire & gas safety cabinets as core maintenance spare part.
