Description

The Bently Nevada 1900/65A 172323-01 is a general purpose equipment monitor designed for continuous machine monitoring and protection across industrial processes. The monitor incorporates four transducer inputs that support 2-wire and 3-wire accelerometers, velocity sensors, or proximity sensors, alongside four dedicated temperature inputs compatible with Type E, J, K, and T thermocouples or 2-wire and 3-wire RTDs. Output interfaces include six configurable relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered output for raw sensor signal routing to diagnostic equipment. Configuration is managed through external 1900 Configuration software to establish relay trip logics based on OK, Alert, and Danger status criteria.

Features

• Accepts four configurable transducer inputs for accelerometers, velocity sensors, or proximity sensors.
• Provides four temperature inputs supporting Type E, J, K, and T thermocouples as well as 2-wire or 3-wire RTDs.
• Integrates six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered signal output.
• Fully programmable relay logic based on OK, Alert, and Danger status states via configuration software.

Applications

• Continuous vibration and temperature monitoring of general-purpose rotating machinery.
• Machinery protection and process asset monitoring in industrial manufacturing facilities.
• Signal routing of raw transducer data to diagnostic instruments and control systems.

Installation Guidelines

• Ensure transducer cabling is correctly routed for 2-wire or 3-wire physical sensor configurations prior to system power-up.
• Ground sensor shielding appropriately to mitigate industrial high-frequency electrical noise and electromagnetic interference.
• Use the official 1900 Configuration software to set relay contact states and map required channel variables to the 4-20 mA recorder channels.
