The DM4001 provides an isolated voltage or current output proportional to temperature as measured with an RTD.

The product can measure 2, 3, or 4 wire resistance elements. The 3 wire configuration provides compensation for lead wire resistance. The 4 wire configuration provides true measurement of the resistance element without lead wire error.

Linearization is provided for .00385 and .00393 alpha platinum resistance elements.

All Wilkerson products are designed with RFI filters and lightning protection to reduce susceptibility to electrical noise and damage by lightning. It utilizes a feedback VCO to develop a pulse train with a duty cycle proportional to the input signal amplitude. This pulse train is coupled through a pulse transformer to the output circuitry, where the duty cycle data is converted to a proportional DC output level.

Connections are made via two 4-pin plug-in terminal blocks. These terminal blocks allow the product to be removed without unwiring the connections.
