Mighty Module MM4408 DC Input Difference Transmitter


MM4408 DC Input Difference Transmitter Output = A - B

Mighty,Module,MM4408,DC,Input,Difference,TransmitterDescription

The MM4408 provides a DC output voltage or current proportional to the difference of two DC inputs. 

Typical input ranges are 4/20 mA, 10/50 mA, 0-1 V, 0-5 V and 0-10 VDC. Other ranges are available down to minimum spans of 1 V or 1 mA DC.

Standard calibration provides 0% output when both inputs are equal.  Full scale (100%) output occurs when A is at 100% and B is at 0%.  Other calibrations are available.

The Module include filtering and conditioning to reduce susceptibility to transients and noisy operations.

Typical Applications

Subtracting flows, weights, etc. for process monitoring, control and data acquisition.

Mounting

The MM4408 is designed to plug into a standard 11-pin 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 mounted socket (DMP011) is available for 35mm symmetrical DIN rail.
