DESCRIPTION

The MM1600 monitors an AC 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. The alarm has a set of red/green LEDs to indicate alarm status.

A 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.

With the latching option, the alarm 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

AC motor/current limit, AC power status or 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 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).  A DIN rail mounted socket (DMP011) is available for 35mm symmetrical rail.
