Triconex CM‑2201 Communication Module Base 7400206‑100

CM‑2201 (7400206‑100) is a communication module base for Triconex TMR safety instrumented system. It provides mechanical mounting and electrical backplane connection for various communication interface cards, maintaining triple‑modular‑redundant bus integrity inside the Tricon safety controller rack.

This base realizes electrical isolation between internal safety bus and external communication circuits. It routes Ethernet and serial signals to termination panels, supporting high‑reliability data interaction between SIS controller and external DCS, HMI and SCADA systems in critical safety‑related automation sites.
