4 CH PT1000 RTD I/P

4-channel analog input - For Pt1000/RTD resistance sensors


This analog input module directly connects to Pt resistance sensors. Two-wire sensors can be connected.

The module automatically linearizes the entire temperature range. A sensor error (short circuit, line break or measurement range overflow) is indicated by a red LED.
