DESCRIPTION

The MM1005 monitors a DC current input 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 logic.  The alarm has a set of red/green LEDs to indicate alarm status.

The module contains a 24 VDC transmitter power supply specifically designed for use with two-wire and other 24 VDC powered transmitters.

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

TYPICAL APPLICATIONS

HI/LO pressure alarm, level/position control.

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 PVC snap track (TRK48). Use CLP-1 hold-down clip if needed. A Killark HK Series explosion-proof housing with dome and 11-pin socket is available (HKB-HK2D-11).  A DIN rail socket (part number DMP011) is available
