The Bently Nevada 1900/65A General Purpose Equipment Monitor is designed to continuously monitor

and protect equipment that is used in a variety of applications and industries. The monitor's low cost makes

it an ideal solution for general-purpose machines and processes that can benefit from continuous monitoring and protection.

The 1900/65A provides four transducer inputs and four temperature inputs. Software can configure each

transducer input to support 2- and 3-wire accelerometers, velocity sensors or proximity sensors. Each temperature

input supports Type E, J, K, and T thermocouples, and 2- or 3-wire RTDs.

The 1900/65A provides six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered output. The user can

use the 1900 Configuration software to configure the relay contacts to open or close according to the OK, Alert and Danger

statuses of any channel or combination of channels, and to provide data from any variable from any channel on any recorder output.

The dedicated buffer output can provide the signal for each transducer input.

A Modbus® Gateway option allows the monitor to provide static variables, statuses, event list, time and date information directly to

any Modbus client, including Distributed Control Systems (DCSs), Supervisory Control and Data Acquisition (SCADA) systems,

Programmable Logic Controllers (PLCs), or System 1® software. The monitor uses an internal counter and a Modbus client/master

time reference to generate time and date information. Users can upgrade monitors without the Modbus Gateway by ordering

the 1900/01 Communications Upgrade (see the Ordering Information section). The 1900/65A supports Modbus communications

via Ethernet and a software-configurable RS232/485 serial port.
