1900/65A-01-03-00-01 Bently Nevada General Purpose Equipment Monitor

Product Description

1900/65A-01-03-00-01 is Bently Nevada standalone machinery condition monitor, powered by 110–220V AC 50/60Hz external power supply. This variant is equipped with remote display with 10’ unassembled PVC cable, DIN rail mounting type, no hazardous area certification, and built-in Modbus RTU communication interface. It features 4 transducer input channels for vibration, displacement or speed signals and 4 RTD temperature channels for continuous condition monitoring of rotating and reciprocating plant equipment. It supports relay alarm/trip outputs and 4-20mA analog outputs to transmit measurement data to DCS, PLC or recorder systems, and realizes remote data reading and parameter configuration via Modbus network.

FAQ

Q: What does suffix 01-03-00-01 mean?
A: 01 = 110–220V AC power; 03 = remote display with 10’ unassembled PVC cable; 00 = DIN rail mount, no hazardous area approvals; 01 = Modbus RTU communication interface.

Q: What is the advantage of this model compared to versions without communication?
A: It supports Modbus RTU, which allows real-time measurement values, alarm status and fault information uploaded to DCS/PLC for centralized plant monitoring.

Q: Is 1900/65A series still in production?
A: The 1900/65A series is still active by Bently Nevada (Baker Hughes). Original new units are available via authorized distributors.
