BENTLY NEVADA Monitor Module - 1900/65A-A00-B01-C01-D00-E01

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 generalpurpose 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 builtin 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.
