Intrinsic Safe

The main function of intrinsic barriers – is to ensure the safe connection and operation are installed in hazardous areas of simple sensors and devices with power consumption and power consumption is not higher than allowed, and also more energy-intensive equipment permitted for use in hazardous areas and has the appropriate type of protection. Now widely used two types of barriers, intrinsic safety: the shunt diodes and electrically isolated. Check with to learn more. The wiring connectable to electrical equipment with a type of protection "intrinsically safe", must meet the following requirements: 1) intrinsically safe circuits must be separated from other circuits in compliance with GOST 22782.5-78 * 2) use a single cable for iskroopasnyh and intrinsically safe circuits is not allowed, and 3) wire intrinsically safe circuits of high frequency should have no loops, and 4) wire insulation intrinsically safe circuits should have a distinctive blue color. Allowed to mark only the blue wires, 5) wire intrinsically safe circuits must be protected from interference that violate their Intrinsic..
