SAFETY BARRIER DATA SHEET This safety barrier is used for intrinsic safety explosionproofing of electronic instrumentation systems to ensure safe operation in the process of generating explosive gases. It is used in combination with field instruments installed in hazardous area as an intrinsic safety explosion-proof system. PWX SPECIFICATIONS Explosion-proof structure: Intrinsic safety explosion-proof Applicable gas: FCX transmitter gas (3aG4) O ptical switch signal converter gas (3aG4 and 2G4) Optical repeater gas (3aG4 and 2G4) Optical fiber type multi-point temperature converter gas (3aG4 and 2G4) FCX-AII, AIII series transmitter (Ex ia IICT4) Safety hold rating: 250V AC and 250V DC Combination instrument: FCX Series transmitter, optical repeater, optical switch signal converter, optical fiber type multi-point temperature converter (Inspection guarantee No. of safety barrier should be attached to instrument) FCX-AII, AIII series transmitter (Device Certification) Ambient temperature of combination instrument: 60˚C or less Modification of combination instrument: M odification is prohibited (unit can be replaced). Grounding: Class A grounding Mounting method: S afety barrier should be installed in non-hazardous area using the supplied clip screw.
