The Bently 1900/65A universal device monitor is designed to continuously monitor and protect devices used in a variety of applications and industries. The low cost of this monitor makes it an ideal solution for general-purpose machines and processes that can benefit from continuous monitoring and protection.

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

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

Users define display operations and Modbus gateway register maps by using software running on a laptop or PC, create a configuration file and download the file to the display 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 to make changes.

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