The Altronic DSM-4689DUS setpoint monitor is a universal
microprocessor-based instrument designed to monitor critical
process variables represented by an analog voltage signal.
Typical uses are measurement of pressures, temperatures
and speed. In addition, an additional input is provided for
connection to a negative ground C.D. ignition system for the
tachometer, overspeed and hourmeter functions. The device
can be powered from any 12- or 24-volt source capable of
supplying 10 watts. Modbus RTU communications is standard.
The DSM-4689DUS has two individual setpoints (high and low)
per channel. One solid state form C output switch is provided
for connection to the machine protection system. Fault
information in order of occurrence is available on the display
and via the serial port. The front panel sealed membrane
keypad provides easy selection and adjustment of the units,
range, setpoints and other configuration data. The DSM-
4689DUS is housed in a gasketed, anodized aluminum case
making it ideal for oilfield and other demanding-environment
applications.
