3500/05 RIM IO Module Bently Nevada Parts 125768-01 Bently Nevada Rack Interface Rear Panel

The 125768-01 is the factory-standard Rack Interface Module I/O (RIM I/O) rear panel used with the 3500/05 RIM in every 3500 protection rack.

This single, hot-swappable board consolidates all external communication and analog output terminations:

• RS-232 / RS-485 - local laptop or DCS serial link
• Modem enable - dial-out alarm call service
• System 1® Ethernet - 10/100 Base-TX for BN software suite
• Four isolated 4-20 mA current sources - proportional to any monitor value (speed, vibration, thrust, etc.)
• Keyphasor buffered output - drives third-party instruments

By integrating all I/O on one shielded, surge-protected assembly, 125768-01 eliminates extra terminal blocks, reduces wiring errors and maintains API 670 / SIL 2 integrity.

• Steam & gas turbines - export vibration to DCS via 4-20 mA
• Centrifugal compressors - dial-out modem alarms to remote SCADA
• Pumps & fans - local RS-485 Modbus link to PLC
• High-speed balancing machines - buffered Keyphasor to portable analyzer
• Offshore platforms - single-cable Ethernet to System 1® onshore
