4. Intrinsic Safety Explosion Protection Instrumentation Intrinsic Safety Explosion Protection Instrumentation Using Barriers  Category of Barriers Classified roughly, barriers includes Zener barriers and insulating barriers (intrinsic safety barriers). Select the best one as your system, with the knowledge of their future. (1) Feature of Zener barriers Zener barrier has a simple construction which consists of just Zener Diode and resistance.
Page 71 4. Intrinsic Safety Explosion Protection Instrumentation (5) Failure rate The construction of Zener barriers is simple, because they carry out the function for security just with Zener Diode and resistance. On the other hand, insulating barriers consist of various parts, because they have the function of insulation and energy restriction. Therefore, the failure rate of insulating barriers is generally higher than that of Zener barriers.
Page 72 4-10 4. Intrinsic Safety Explosion Protection Instrumentation Wiring of Intrinsic Safety Explosion Protection  An intrinsic safety circuit must be isolated from non-intrinsic safety circuit. Wiring should be prepared in accordance with IEC 60079-14, NEC (National Electrical Code : NFPA-70), or the standard of the country and the area in which it is set. The wiring in cabinet should keep the distance to non-intrinsic safety circuit.
Page 73 4-11 4.
