Bently Nevada 1900/65A-00-01-01-00-00 General Purpose Equipment Monitor

Description

The Bently Nevada 1900/65A-00-01-01-00-00 general-purpose equipment monitor provides continuous monitoring and machinery protection for general-purpose industrial equipment. Designed for standalone or integrated operation, the 1900/65A-00-01-01-00-00 processes inputs from four transducer channels and four temperature channels. The 1900/65A supports 2-wire and 3-wire accelerometers, velocity sensors, and proximity probes on channels 1 through 4, while channels 5 through 8 accept Type E, J, K, and T thermocouples as well as 2-wire and 3-wire RTDs. Output features include six programmable SPDT relays, four 4-20 mA recorder outputs, and dedicated buffered outputs for dynamic signal analysis. This configuration includes an attached display module, DIN rail mounting hardware, and Modbus communication support over Ethernet and software-configurable RS232/RS485 serial ports.

Features

• Four configurable transducer input channels supporting acceleration, velocity, radial vibration, thrust, position, and speed measurements
• Four dedicated temperature channels supporting Type E, J, K, and T thermocouples and 2- or 3-wire RTDs
• Six SPDT relay outputs with programmable voting logic based on OK, Alert, and Danger status conditions
• Four 4-20 mA proportional recorder outputs configurable to any channel variable
• Dedicated buffered output channels providing unscaled raw signals for dynamic analysis
• Modbus Gateway capability enabling serial and Ethernet Modbus communications with DCS, PLC, and SCADA systems
• Integrated display module attached directly to the monitor module for local visualization and configuration
• Non-volatile memory storage for configuration settings created via 1900 Configuration Software

Applications

• Pumps and industrial fans
• Compressors and blowers

Installation Guidelines

• Mount the unit onto a standard 35 mm DIN rail using the provided mounting clip.
• Ensure adequate ventilation space around the Monitor Module housing during panel integration.
• Wire input sensors using shielded twisted-pair cables according to the field wiring requirements.
• Maintain a dedicated low-impedance ground connection to the chassis ground terminal.
• For zener barrier installations, remove the internal ground jumper to isolate circuit common from chassis ground.
• Use 18 to 36 Vdc external DC power supply lines with appropriate circuit protection.
