Mighty Module MM1700 Frequency Input Single Alarm


MM1700 Frequency Input Single Limit Alarm

Mighty,Module,MM1700,Frequency,Input,Single,AlarmDescription

The MM1700 monitors a frequency 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 wide range of input sensitivity allows the MM1700 to be driven from low level magnetic pickups as well as logic level signals. A threshold adjustment sets the minimum input amplitude the module will process. This allows the user to trade off sensitivity versus noise rejection. An optional pullup resistor (Option P) permits use with contact-closure or open-collector inputs.

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

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-11).  A DIN rail mounted socket (P/N DMP011) is available for 35mm symmetrical rail.
