Product Details

133323‑01 is 3500/92 communication gateway module for Bently Nevada 3500 machinery protection rack. It is an independent full‑height module without matching rear I/O sub‑board.

It supports Modbus TCP over Ethernet and dual‑channel Modbus RTU over RS485 serial bus,works as Modbus slave. It reads all measurement values,alarm status and fault information from 3500 rack,then transmits data to external DCS,PLC or host monitoring system. RS485 dual‑bus design supports redundant bus wiring for high‑reliability field site.

This gateway module does not participate in hardware protection voting logic. It supports hot‑swap replacement without affecting protection function of other monitor modules. It completes register mapping configuration via rack configuration software.

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