The Role and Installation Precautions of Intrinsic Safe Barriers

In the modern industrial production process, the reliability of automated control systems directly affects the safety and production efficiency of factories. Especially in industries such as petroleum, chemical, and metallurgy, where places with explosive hazardous substances frequently appear, ensuring the safety of these areas is crucial. Intrinsic Safe Barriers play a critical protective role in such environments.

The Role of Intrinsic Safe Barriers

Isolation safety barriers are instrumentation devices that connect intrinsically safe circuits and non-intrinsically safe circuits. Their main function is to limit the voltage and current supplied to intrinsically safe circuits within a certain safe range to prevent potentially explosive dangerous situations. In chemical enterprises, any kind of electrical equipment may cause explosions. Sparks caused by friction, static electricity, and high temperatures are almost unavoidable in industrial production. Therefore, isolation safety barriers provide an important protective measure for industrial production, ensuring the safety of the production process.

Installation Precautions for Intrinsic Safe Barriers

Installation location

Intrinsic Safe Barriers should be installed in a safe area to ensure their normal operation and avoid potential hazards.

Insulation strength

The insulation strength of the connecting wires must be greater than 500V to ensure the safety and stability of the circuit.

Conductor cross-sectional area

The cross-sectional area of soft copper wires leading to hazardous areas must be greater than 0.5mm², ensuring the safety of current transmission.

Wire marking

Intrinsic Safe Barriers feature blue terminals for intrinsically safe connections. Intrinsically safe wires should ideally be marked with blue. Intrinsically safe wires and non-intrinsically safe wires in wiring ducts should be laid out separately using their respective protective sleeves to avoid interference between circuits.

Power-on testing

When conducting a standalone power-on test of an isolation safety barrier, one must pay attention to the model, power polarity, voltage level, and terminal markings on the enclosure of the isolation safety barrier to ensure compliance with design and product specifications.

Explosion-proof instruments

Field instruments connected toIntrinsic Safe Barriers must undergo explosion-proof tests by relevant departments and obtain explosion-proof certification to ensure their safe use in hazardous environments.

Maintenance and replacement

If the internal module of anintrinsic safety barrier requires repair or replacement due to damage, it should be handled by the manufacturer. Do not attempt to disassemble or repair it yourself to avoid potential safety hazards.
