4119A Tricon SIS Serial Communication Interface Module

Feature & Principle

It is Triconex EICM enhanced intelligent communication module (part number 4119A), dedicated for Tricon triple modular redundant safety instrument system. It realizes data exchange between Tricon controller and external Modbus devices, TriStation engineering workstation and printers. It has four configurable serial ports supporting RS232/RS422/RS485 and one isolated Centronics parallel port. Each serial port can be set as Modbus master or slave, with galvanic isolation between field side and safety backplane. It supports online hot replacement without stopping the safety system, and undertakes interlocking data interaction, event logging and engineering debugging tasks for SIS.
