Technical Specifications Intrinsically safe isolation barrier; Galvanic isolation between safe side and hazardous side; Suitable for 4-20mA analog signals; Operating temperature -40°C to 70°C.
Functional Features Energy limiting for hazardous circuits. Galvanic isolation to suppress ground loop interference. Fault monitoring for field circuit. Protect control system from surge and overvoltage.
Application Scenarios Chemical, petrochemical, oil & gas plants, used for transmitters installed in Zone 0, Zone 1 explosive hazardous areas.
Performance Parameters High isolation voltage; Low signal attenuation; Compliance with ATEX intrinsic safety standards.
Structural Characteristics DIN rail mounted compact module, plug-in terminal blocks for field and control side wiring. LED indicator for power and fault state.
Working Principle Internal circuit limits maximum voltage and current delivered to field hazardous side. Galvanic isolation blocks ground loop noise. The analog signal passes through isolation circuit and transmits between field instrument and control system.
Installation Requirements Install on standard DIN rail inside safe area cabinet. Separate hazardous signal wiring from high voltage power cables. Complete reliable protective grounding.
Usage Notes Follow intrinsic safety wiring specification. Do not modify internal circuit of barrier. Verify certificate matching before using in explosive area.
