RTD Temperature converter and Resistance converter, DAT4531B

General Description

The RTD Temperature converter and Isolated Resistance converter DAT4531B is a din rail mount Temperature converter. It is programmable by PC or DIP Switches. The DAT4531B accepts signal from various RTD's Pt100, Pt1000 Ni100, Ni1000. and resistance up to 2000Ohms. The DAT4531B converts this signal and makes the scale linearized. The DAT4531B provides Voltage or Current output.
