Triconex 4201 Remote Extender Module
Product Overview
- Description: The Triconex 4201 is a Remote Extender Module (RXM) designed for use in Triconex safety instrumented systems (SIS), part of Schneider Electric’s Triconex product line. It enables I/O modules to be located several kilometers away from the main chassis, acting as a repeater and extender of the Tricon I/O bus while providing ground loop isolation.
