This unit
The GE / Bently Nevada 81545-01 is a transducer I/O and relay interface module for the Bently Nevada 3300 Series Monitoring System. This signal input/alarm output board provides dual epoxy relays and terminal connectivity for transducer signals, Keyphasor references, and vibration sensor inputs in continuous machinery protection applications. The module processes accelerometer and velocity sensor data, applies user-defined vibration thresholds, and delivers alarm/shutdown relay outputs and 4-20 mA analog signals to downstream DCS/PLC systems.

Converts vibration signals to 4-20 mA analog output for DCS/PLC integration
Monitors shaft axial position for early thrust bearing failure detection via LVDT signals
Supports casing growth measurement on expansion monitor applications
Dual epoxy relays rated for industrial duty cycles
Typical Applications
Machinery condition monitoring and protection in petroleum and process industries
Vibration-based fault detection and alarm generation
Thrust bearing axial position monitoring
Casing expansion monitoring on large rotating equipment
API 670–compliant machinery protection systems
Compatibility & Integration The 81545-01 integrates with Bently Nevada 3300 Series monitors (3300/20, 3300/25, 3300/45, 3300/48) and is also compatible with 3300 and 3500 Series Monitoring Systems. It functions within modular racks that include system monitors, power supplies, and additional monitor modules to create scalable, application-specific machinery protection architectures.
