Intrinsic Isolated Barrier

What Is Isolation Barrier?

Intrinsic safety barriers and isolatorsuse 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 isolation 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 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 Intrinsically Safe 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.

Intrinsic isolated barrier

The isolated barriers for hazardous areas in our safety automation system for sale are associated equipments of explosion-proof instruments that will not affect the function of the measurement system in a normal situation. The isolation barrier is placed on one side of the security site, when the explosion-proof system fails, the intrinsic barriercan limit the energy (electric energy) which can enter the dangerous site to safe values to ensure the safety of the scene.

Difference

What is Safety Level of Intrinsically Safe Electrical Equipment?

IA

IA means that the explosive gas mixture cannot be ignited under normal operation, one counting failure, and two counting failures. IA-level intrinsically safe electrical equipment can be used in hazardous locations in Zone 0, Zone 1, and Zone 2.

IB

IB means that explosive gas mixtures cannot be ignited under normal operation and a counting failure. IB's intrinsically safe electrical equipment that can be used in hazardous locations in Zone 1 and Zone 2.

IC

IC means that explosive gas mixtures cannot be ignited under normal operation. IC-level intrinsically safe electrical equipment can be used in zone 2 hazardous locations.
