Mighty Module MM7010 Frequency Input Transmitter

MM7010 Frequency Input Transmitter

Mighty,Module,MM7010,Frequency,Input,Transmitter Description

The MM7010 provides a DC output voltage or current proportional to the frequency of the input signal. It is useful for measuring flow, speed of motors, conveyors, or other devices that can create a periodic signal proportional to the desired function. The wide range of input sensitivity allows the MM7010 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 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).
