DESCRIPTION

The MM1000A is a lower cost alternative to the MM1000 DC limit alarm for standard applications. The MM1000A monitors a DC input and trips a dpdt, 5 A relay when the input exceeds the desired level. The alarm has a green LED to indicate relay status.

Setpoint adjustment is provided by a 25-turn trimpot, adjustable from below 0% to above 100% of span. Deadband, also a 25-turn trimpot, is adjustable from below 1% to above 100% of span. A user-changeable jumper may be changed to provide high or low trip.

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

For options or input ranges not provided by MM1000A, refer to MM1000.

TYPICAL APPLICATIONS

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

MOUNTING

The MM1000A 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 2 3/4 inch wide PVC snap track (TRK48). Use CLP-1 hold-down clip, if needed.  Killark HK Series explosion-proof housings are available with 11-pin sockets. Order HKB-HK2D-11.  A DIN rail mounted socket (P/N DMP011) is available for 35mm symmetrical rail.
