It provides RS232 and RS422 physical serial interfaces. Users can connect external configuration software to finish rack parameter upload and download. It outputs real‑time measurement data,alarm status and historical event logs. This module does not participate in hardware protection voting logic,system protection function keeps working when RIM fails. It supports hot‑swap operation.

For TMR triple‑modular‑redundant system,please select corresponding TMR version RIM module.

Note: This is legacy 3500 series spare component,widely used for replacement of turbine and compressor TSI monitoring & protection systems.
