Intrinsic safety barriers and isolators use intrinsically safe explosion-proof and functional safety technologies and adopts various measures such as rapid cut-off, isolation, and energy limiting to ensure that the energy transmitted to the field equipment in the hazardous area is intrinsically safe, thereby preventing dangerous energy from entering the danger zone and causing an explosion.

An isolated barrier, such as the digital input barrier, is a key interface unit in the intrinsically safe explosion-proof control system. The intrinsically safe barrier or the intrinsic safety barrier with quite affordable intrinsically safe barrier price made by CHENZHU, one of the top intrinsic safety barrier manufacturers in China, is made under a strict production process and tested by a series of quality assurance systems.

What is Difference Between Intrinsic Isolated Barrier and Isolator?

Isolator

The isolator is used to adjust, isolate and transform all kinds of field instrument signals into the normal signals or special signals specified by users which can be accepted by the computer, DCS, PLS, etc. It is also used to isolate control equipment and operational equipment from electronics, like a relay.
