Description

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
