The MM4003 provides an output voltage or current proportional to the slide position of a potentiometer. It is useful in monitoring valve or actuator position and for creating test signals.

All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning.

Any value potentiometer from 100 ohms to 100 kilohms can be used. The module utilizes a stable 1 V power supply to excite the potentiometer. As the potentiometer is rotated, the slide voltage is proportional to the wiper position.

TYPICAL APPLICATIONS

Tank level, valve or actuator position control, monitoring and data acquisition, creating test signals.
