Typical Applications: DC Motor/current limit, level/position control, HI/LO pressure alarm, power demand warning.. Provides a DPDT Relay Contact Closure at a Preset DC Input. Standard Fail-Safe Operation. Red and Green LED Alarm Status Indicators. Adjustable Deadband. The MM1000 monitors a DC input signal and trips a dpdt, 5 A relay when the input exceeds the desired level. Normal operation has the relay energized for the non-alarm condition and de-energized for an alarm condition. This provides a fail-safe alarm condition for loss of power to the module. Option R reverses this mode of operation. The alarm has a set of red/green LEDs to indicate alarm status. The MM1000 deadband adjustment allows a deadband of 0.5% to 100% of span to be set into the module. The deadband is symmetrical about the setpoint.
