Mighty Module MM1200 Thermocouple Input Single Limit Alarm


MM1200 ThermocoupleInput Single Limit Alarm

Mighty Module,MM1200,Thermocouple,Input,Single,Limit,AlarmDescription
The MM1200 monitors any thermocouple 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 the 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 must be momentarily interrupted to reset the alarm.

Cold junction compensation is provided by a solid state temperature sensor embedded in the thermocouple terminal strip.  The module includes filtering and conditioning to reduce susceptibility to transients and noisy operations.

Upscale burnout protection is provided as standard. In the event the thermocouple opens, the module behaves as though the input goes offscale high. Option B provides downscale burnout protection (module behaves as though the input goes low).

Typical Applications

Heater/cooler control, HI/LO temperature alarm.

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