Triconex EICM4119A Communication Module

Feature & Principle

It is Triconex EICM4119A enhanced intelligent communication module for Tricon triple modular redundant safety instrumented system. It offloads communication tasks from the main processor, realizing data interaction between Tricon controller and Modbus devices, TriStation debugging software and printers. Four isolated serial ports support RS232, RS422 and RS485. Each port can be independently configured as Modbus master or slave. 500VDC port isolation protects the safety system from external interference. Online replacement is available without system shutdown.
