The 3500/20 is the mandatory Rack Interface Module for every Bently Nevada 3500-series rack.
Installed in Slot 1 (adjacent to the power supplies), it acts as the central communication gateway between the 3500 monitors and external hosts such as DCS, PLC, System 1®, TDXnet, TDIX or DDIX. The RIM handles rack-wide configuration, real-time data retrieval, alarm forwarding and diagnostics, yet it is outside the protection path, so its failure never disables critical machine tripping.

Key Benefits
Ø Slot-1 commander – mandatory first module; auto-detects all cards for plug-and-play commissioning.
Ø Multi-protocol gateway – front RS-232 for local laptop, rear RS-422 for 1.2 km plant runs, Ethernet via 3500/92 for DCS/SCADA.
Ø Non-blocking architecture – located outside protection path; communication loss never inhibits alarms or relays.
Ø 32-node multidrop – single RS-485 bus links up to 32 racks to one SCADA port, cutting cabling costs.
Ø Hot-swap & hot-spare – LEDs (OK, TX/RX, TM) allow on-line replacement < 1 min.
Ø Harsh-environment ready – conformal-coated PCB and –40 °C storage rating suit offshore, desert and arctic installations.
