Description
The 125768-01 RIM I/O Module is the primary interface for the Bently Nevada 3500 rack, supporting proprietary protocols to configure the rack and retrieve machinery data. Installed in slot 1 next to the power supplies, 125768-01 communicates with external processors such as TDXnet, TDIX, and DDIX. For Triple Modular Redundant (TMR) systems, 125768-01 performs monitor channel comparison, continuously checking outputs from three redundant monitors and flagging any channel outside the configured percentage. Typical power consumption of 125768-01 is 4.75 W. Front panel RS232 serial communications operate at 38.4 k baud, with maximum cable lengths of 30 m (RS232) or 1200 m (RS422). Front panel LEDs include OK, TX/RX, TM, and CONFIG OK, and the I/O module provides 5 A @ 24 Vdc / 120 Vac relays for alarm, trip, and reset functions. Operating temperature ranges from 0°C to +50°C, storage -40°C to +85°C, with 95% non-condensing humidity. 125768-01 enables reliable static and dynamic data collection for automation and process control applications within 3500 monitoring racks.
Applications
Perform Turbine Trip and Shutdown Control
125768-01 relays can switch turbine trip circuits rated up to 5 A, 120 Vac or 24 Vdc, ensuring immediate response to overspeed or vibration thresholds.
Forward Pump Alarm Signals to Control Room
Using RS232 or RS422 connections, 125768-01 transmits pump temperature and vibration alarms to centralized automation systems or SCADA software for operator intervention.
Collect Dynamic Vibration Data
125768-01 interfaces with Bently Nevada Transient Data Interface modules, capturing dynamic vibration data and sending it to data acquisition systems at 38.4 k baud.
Reset or Inhibit Rack Functions
The module provides system contacts for rack reset, trip multiply, and alarm inhibit, allowing operators to safely manage automation processes from the front panel.

Competitive Advantage
Integrate RIM Functions and Data Collection
125768-01 consolidates rack configuration, TMR monitor comparison, and data acquisition in a single module, reducing hardware complexity in automation racks.
Switch High-Power Relays Directly
With 5 A @ 24 Vdc / 120 Vac capacity and 120 W / 600 VA switched power, 125768-01 drives alarm, trip, and reset circuits without external relays.
Verify System and Communication Status Quickly
Front panel LEDs (OK, TX/RX, TM, CONFIG OK) on 125768-01 allow operators to confirm module operation and active communication instantly.
Operate in Standard Industrial Environments
Operating from 0°C to +50°C with 95% non-condensing humidity, 125768-01 can be installed in control cabinets near turbines, compressors, or pumps without additional cooling or protective enclosures.
