1900/65A General Purpose Equipment Monitor
Bently Nevada* Asset Condition Monitoring
Description
The 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.
Inputs
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.
Outputs
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.
Configuration
The user defines monitor operation and the Modbus Gateway register map by
using software running on a laptop or PC to create a configuration file and
download the file to the monitor through the built-in Ethernet connection. The
1900/65A permanently stores configuration information in non-volatile memory,
and can upload this information to the PC for changes.
Display Module
The 1900/65A supports an optional display/keypad to view channel information
or make minor configuration changes. This allows the 1900/65A to operate as a
stand-alone package. If desired, the user can mount the display up to 75 metres
(250 feet) from the Monitor Module
