Mighty Module MM7501 DC input Integrating Totalizer Pulse Output Transmitter


MM7501 DC input Integrating Totalizer Pulse Output Transmitter

Mighty,Module,MM7501,DC Input,Integrating,Totalizer,Pulse,Output,TransmitterDescription

The MM7501 is used, together with a counter, to integrate or totalize flow and other signals. Its output is a pulse rate proportional to a DC input. When totalized on a counter, the pulses indicate the total flow or other quantity being measured.

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.

The MM7501 includes a frequency scaler (binary pulse rate divider) which, together with wide-ranging zero and span controls, provides a 4096:1 range of output pulse rate adjustment.

This allows the output to be scaled in engineering units (one pulse equals 1,000 gallons, for example). The output may be an spdt relay, a voltage pulse suitable for driving a 12 V electromechanical, counter or an open collector output.

The module includes filtering and conditioning to reduce susceptibility to transients and noisy operations. An integrating DC to frequency converter generates the basic pulse rate.

Typical Applications

Totalizing flow, BTU, or any other quantity that can be represented in quantity per unit time.

Mounting

The MM7501 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 mounted socket (DMP008) is available for 35mm symmetrical DIN rail.
