DESCRIPTION

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.
 
The modules include filtering and conditioning to reduce susceptibility to transients and noisy environments.
 
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 or in a 2 3/4 inch wide track  (TRK48).  Use CLP-1 hold-down clip, if needed, with standard modules.  A Killark HK Series explosion-proof housing with dome and 11-pin socket is available.  A DIN rail mounted socket (P/N DMP011) is available for 35mm symmetrical DIN rail.
