Mighty Module MM4420 DC Input Divider Transmitter


MM4420 DC Input Divider Transmitter Output = A/B

Mighty,Module,MM4420,DC Input,Divider,TransmitterDescription

The MM4420 provides a DC output voltage or current proportional to the quotient (ratio) 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 the output at full scale (100%) when both inputs are at full scale (100%). Other calibrations are available.

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

Typical Applications

Controlling relative speed, mixing rates, compensating flow readings for temperature changes (mass flow = flow rate/temperature), etc.

Mounting

The MM4420 is designed to plug into a standard 8-pin relay socket. Part number MP008 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 8-pin socket is available (HKB-HK2D-8). A DIN rail socket (DMP008) is available for 35mm symmetrical DIN rail.
