Thermistor Splitter, Potentiometer Splitter DAT4631C

General Description

The Thermistor Splitter and Potentiometer Splitter DAT4631C is a din rail mount converter and splitter. The DAT4631C converts and linearizes the signal from PTC and NTC type thermistors and provides two process signal outputs either Voltage or Current. The DAT4631C also converts and splits a Potentiometer input into Voltage or Current. It is programmable by PC or DIP Switches. The DAT4631C accepts signal from KTY81-210, KTY81-220, KTY84-130, KTY84-150, Coster 10K and Coster 1K Thermistors. The Potentiometer range is from 50 kohms. The DAT4631C provides two Voltages or Current outputs that are isolated from the power supply and input.
