The model IS barrier intrinsically safe barrier 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.
The test sockets contained in the COMBICON connectors enable the direct connection of HART® communicators.
The intrinsically safe barrier has been tested for operation with the following WIKA products: LH-20, IL-10,IS-3, DPT-1x, UPT-2x, T32
In intrinsically safe circuits, the intrinsically safe barrier enables the safe operation of these products. A template to create the proof of intrinsic safety can be found at www.wika.com.
