1900/65A-00-00-01-00-00

Bently Nevada 1900/65A-00-00-01-00-00 is a general-purpose equipment monitor. This order code selects 18-36 V DC monitor power, no display, 35 mm DIN mounting and no Modbus option. The built-in Ethernet connection still supports configuration transfer, and settings are retained in non-volatile memory. Typical monitor consumption is 0.35 A and 8.5 W; maximum values are 1 A and 14 W. The operating temperature range is -20 to +70 deg C, with non-condensing humidity up to 95%.

Four transducer channels can process acceleration, velocity, radial vibration, thrust, position or speed according to the software configuration. Four separate temperature inputs support E, J, K or T thermocouples and two- or three-wire RTDs. Sensor type, processing mode and engineering units determine what each connected signal represents. Four independently assigned 4-20 mA recorder outputs convey selected variables to external receiving equipment. They update every 100 ms and support up to 600 ohms loop resistance under the applicable 18-36 V DC loop supply conditions. Output assignment and full-scale mapping are separate from the input channel numbering.

Six SPDT relays use programmable logic based on monitor, channel and variable status, with up to 50 operands per relay. AND logic ignores bypassed channels, while True AND includes them. Latching and normally energized or de-energized operation are configured independently, so bypass and reset behavior must be evaluated together with the actual voting expression.
