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.
Configuration
The user defines monitor operation and theModbus Gateway register map by usingsoftware running on a laptop or PC to create aconfiguration file and download the file to themonitor through the built-in Ethernet
connection. The 1900/65A permanently storesconfiguration information in non-volatilememory, and can upload this information tothe PC for changes.
Display Module
The 1900/65A supports an optionaldisplay/keypad to view channel information ormake minor configuration changes. This allowsthe 1900/65A to operate as a stand-alonepackage. If desired, the user can mount the
display up to 75 metres (250 feet) from theMonitor Module.
