The MM4001 provides an output voltage or current proportional to an RTD input signal. It is useful in measuring temperatures with a variety of RTDs.

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

The module utilizes a single constant current source to excite the RTD. An accurate and stable lead wire compensation circuit uses the third lead of the 3-wire RTD to compensate for the RTD lead resistance.
