Technical Specifications Intrinsic safety isolated barrier for digital output; Galvanic isolation; ATEX certified; Operating temperature -40°C to 70°C.
Functional Features Limit output energy to field hazardous devices. Isolation protection against ground loop noise. Short circuit protection for field circuit.
Application Scenarios Petrochemical and chemical plants, used to drive intrinsically safe solenoid valves, indicator lamps in Zone 0 / Zone1 hazardous areas.
Performance Parameters Fast digital signal transmission; High isolation voltage; Strict energy limiting for explosion protection.
Structural Characteristics Compact DIN rail mount module, pluggable terminals, LED indicators to show power and channel fault status.
Working Principle The control signal from PLC/DCS passes through isolation circuit. Internal energy limiting components restrict voltage and current on field side to safe level, preventing ignition of explosive gas.
Installation Requirements Install in safe control cabinet on DIN rail. Separate intrinsically safe wiring from non-intrinsically safe cable. Ensure good cabinet grounding.
Usage Notes Do not use for non-intrinsically safe field equipment. Follow explosion-proof installation rules. Inspect terminal tightness periodically.
