MM1020 DC Input Dual Limit Alarm Two SPDT Relays Fixed Range

Mighty,Module,MM1020,DC Input,Dual Limit Alarm,Two,SPDT,Relays,Fixed,RangeDescription

The MM1020 monitors a DC input signal and provides two sets of spdt, 5 A alarm relays with two independently adjustable setpoints. Each setpoint has a set of red/green LEDs to indicate alarm status. When the input is between the setpoints, the relays are normally de-energized. When the signal exceeds a particular setpoint, the relay becomes energized. To provide a fail-safe operation (loss of power resulting in an alarm state), select Option R. The module can be supplied as a HI/HI, HI/LO, or LO/LO alarm (HI/LO supplied if not specified).

Standard deadband on both alarms is fixed at 0.5% of span.  (Option A provides adjustable deadband of 0.5% to 100% span.) Option D, latching alarms, has no deadband control. Once the limit has been reached the alarm latches and power to the module must be momentarily interrupted to reset the alarm.

The module includes filtering and conditioning to reduce susceptibility to transients and noisy operations.

Typical Applications

DC motor/current limit, level/position control, HI/LO pressure alarm, power demand warning.

Mounting

The module is designed to plug into a standard 11-pin relay socket.  Part number MP011 is a molded plastic socket suitable for mounting on a flat surface on a 2 3/4 inch wide PVC snap track (TRK48). Use CLP-1 hold-down clip, if needed, with standard Module. A Killark HK Series explosion-proof housing with dome and 11-pin socket is available.  Order HKB-HK2D-11 (standard dome) for use with MM1020.  A DIN rail socket (part number DMP011) is available for 35mm symmetrical rail.
