Triconex IMFF4703X Fiber I/O Bus Interface Module Tricon CX SIS

Description

Product Overview

TRICONEX IMFF4703X is a fiber I/O bus interface module dedicated for Tricon CX safety instrumented system. It establishes long-distance fiber communication between main rack and 8131X expansion chassis to realize remote I/O rack extension. With TMR triple modular redundancy architecture, fiber electrical isolation and strong anti-EMI performance, it acts as critical spare part for ESD and FGS safety interlock systems. New original surplus stock, 1-year warranty.
