Mighty Module MM1000A DC Input Single Limit Alarm

MM1000A DC Input Single Limit Alarm

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.
