RTD Splitter, Resistance Splitter DAT4631B

General Description

The RTD Splitter and Resistance Splitter DAT4631B is a din rail mount converter and splitter. The DAT4631B converts and linearizes the signal from RTD's and provides two process signal outputs either Voltage or Current. The DAT4631B also converts and splits a Resistor input into Voltage or Current. It is programmable by PC or DIP Switches. The DAT4631B accepts signal from Pt100, Pt1000, Ni100, Ni1000. The Resistance range is from 0-2000 Ohms, the minimum span is 50 Ohms. The DAT4631B provides two Voltages or Current outputs that are isolated from the power supply and input.
