Features
Input signal 0 or 4 ... 20 mA, available source or non-source available
With SIL2 certification according to IEC 61508/IEC 61511 standard
Two-way transmission of HART® signals

Description
IS Barrier type safety barrier is used in conjunction with intrinsically safe 4… 20mA output sensor. Both 2-wire and 4-wire transmitters can be connected by using different junction blocks.
The analog measurement data is transmitted as a current from the hazardous area to the safe area. At the output, the safety barrier can be operated as a source and a non-available source.
The test port integrated in the COMBICON connector can be directly connected to the HART® user.
Safety barriers can be used with the following products: WH-20, IL-10, IS-3, IPT-1x, DPT-1x, UPT-2x, T32
In the intrinsically safe circuit, the safety barrier ensures the safe operation of these products. Intrinsic safety instructions please check the official website of Wica.
