Intrinsic safety explosion barrier is an explosion-proof device with single channel, Zener-diode DC circuit that enables interactive electric signaling without short circuit while controlling energy transmission in order to prevent ignition in explosive atmosphere. 1.Applicable to Zone 0. 2.A-class ground is not necessary since the input and output are insulated each other. 3.When serially connected to a transmission circuit, the barrier protects the circuit and components in hazardous area from being affected by a serious accident in the non-hazardous area. 4.Despite in the hazardous location, conventional wiring is available. 5.Intrinsical proof of operational signal is figured out easily and at lower cost. 6.SAF100-5 safety barrier employ crimping terminal wiring method. 7.As SAF100-5 safety barrier has protection circuit, it will be not broken if you wired in the wrong polarity. 8.LED indicates the condition of the input and output Model code ＳＡＦ100-5 Explosion-proof construction Intrinsic safety construction（EｘｉａⅡC) Rated voltage ＤＣ24Ｖ±10% Maximum voltage of a intrinsic safety circuit ＤＣ29.4Ｖ Max. allowable voltage ＤＣ25.95Ｖ Maximum current of a intrinsic safety circuit 93.8ｍＡ Electric power of a intrinsic safety circuit 0.689W Ambient temp. -20～50℃ Basic circuit figure Does not need A-class ground. Operating condition 1.Place the valve in non-hazardous area. 2.Perform single grounding using type A ground. 3. Parts and connections cannot be changed. 4. Use with specified solenoid valves. 5. Allowable inductance for external connection: 2mH / Capacitance: 0.05 μF
