R. STAHL 9180/21-77-11s Resistance Temperature Detector Isolating Transducer

Article No.: 160502

Product Overview

The R. STAHL 9180/21-77-11s is an Ex i resistance transducer for the intrinsically safe operation of resistance thermometers of type Pt100 (9180/.0) or Pt1000 (9180/.1). The resistance measured at the input is transferred to the output and can thus be measured by an I/O card. Auxiliary power, output, and intrinsically safe input are galvanically isolated.

Ex i resistance transducer 9180/.0 for Pt100 or 9180/.1 for Pt1000
Unique two-channel device with a space requirement of only 8.8 mm per channel
For 2-, 3-, and 4-wire circuits
