Triconex 4200 Remote Extender Module (RXM) in stock

Triconex 4200 is a Remote Extender Module for Triconex Tricon TMR safety instrumented system(SIS). It adopts single-mode fiber to realize long-distance communication between the main controller rack and remote I/O chassis, separating control hardware geographically while maintaining triple redundant safety data transmission.

This module supports up to 15km fiber transmission distance, with built-in optical link and hardware diagnostic functions. It adopts TMR triple modular redundancy architecture and supports hot-swap replacement, widely used for ESD, FGS safety cabinet transformation, spare parts replacement and distributed safety interlock projects.

FAQ

• 1. Q: What is Triconex 4200?
      A: It is single-mode fiber remote extender module for Tricon SIS, used for long-distance connection between main rack and remote I/O chassis.

• 2. Q: What is the difference between 4200 and 4210?
      A: 4200 uses single-mode fiber with max 15km distance, while 4210 is multi-mode fiber type limited within 2km.

• 3. Q: Can 4200 be hot swapped?
      A: Yes, it supports hot swap, module replacement will not shut down the whole Tricon safety system.
