Industrial repeater IS Barrier

The model IS barrier intrinsically safe repeater power supply has been designed for applications in combination with intrinsically safe 4 ... 20 mA sensors. By using different connection terminals, 2-wire as well as 4-wire transmitters can be connected. The analogue measured value is transmitted to the non-hazardous area, galvanically isolated from the hazardous area. On the output side, the repeater power supply can be operated as supplying or non-supplying. Applications Chemical, petrochemical industry Oil, natural gas Machine building Special features Input 0/4 ... 20 mA, supplying and non-supplying Suitable for SIL 2 per IEC 61508/IEC 61511 Bidirectional HART® signal transmission
