Thermocouple Splitter, mV Splitter DAT4631A

General Description

The Thermocouple Splitter and mV Splitter DAT4631A is a din rail mount converter and splitter. The DAT4631A converts and linearizes the signal from a thermocouple and provides two process signal outputs either Voltage or Current. The DAT4631A also converts and splits mV signals into Voltage or Current. It is programmable by PC or DIP Switches. The DAT4631A accepts signal from K,J,S,R,B,E,T, and N type Thermocouples. The mV range is from - 100 mV up to 800 mV, the minimum span is 5 mV. The DAT4631A provides two Voltages or Current outputs that are isolated from the power supply and input.
