The 1900/65A Universal Device Monitor is designed to continuously monitor and protect equipment for a variety of applications and industries. The low cost of the monitor makes it an ideal solution for general-purpose machines and processes that benefit from continuous monitoring and protection.

input

The 1900/65A offers four sensor inputs and four temperature inputs. The software can configure each sensor input to support 2 – and 3-wire accelerometers, speed sensors, or proximity sensors. E, J, K, and T thermocouples are supported for each temperature input, as well as 2-wire or 3-wire RTDS.

output

The 1900/65A offers six relay outputs, four 4-20 mA logger outputs, and a dedicated buffer output. Users can use the 1900 configuration software to configure relay contacts to open or close according to the normal, alert, and hazardous states of any channel or combination of channels, and to provide data on any variable from any channel on any recorder output. A dedicated buffer output can provide a signal for each sensor input.

The Modbus gateway option allows the monitor to provide static variables, states, event lists, time and date information directly to any Modbus client, These include distributed control systems (DCS), supervisory control and Data acquisition (SCADA) systems, Programmable logic controllers (PLCS), or System 1 software. The monitor uses internal counters and Modbus client/master time references to generate time and date information.

Users can upgrade the monitor without the Modbus gateway by ordering the 1900/01 Communications upgrade (see the Ordering Information section).

The 1900/65A supports Modbus communication over Ethernet and a software-configurable RS232/485 serial port.

configuration

Users define monitor operations and Modbus gateway register maps by using software running on a laptop or PC to create a profile and download the file to the monitor via a built-in Ethernet connection.

The 1900/65A stores configuration information permanently in non-volatile memory and can upload this information to a PC for changes.

Display module

The 1900/65A supports an optional monitor/keyboard to view channel information or make minor configuration changes. This allows the 1900/65A to run as a separate package. If desired, the user can install the display up to 75 meters (250 feet) away from the monitoring module
