Technical Specifications Intrinsic safety type; Digital discrete signal; Galvanic isolation; ATEX certification; Operating temperature -40°C ~ 70°C.
Functional Features Energy limitation for hazardous field circuit. Isolation eliminates ground loop interference. Wire break detection function. Surge protection for control side.
Application Scenarios Oil, gas and chemical industries, for limit switches, proximity sensors and contact input devices located in explosive hazardous zones.
Performance Parameters Low signal transmission delay; High dielectric isolation; Meet intrinsic safety energy limitation requirement.
Structural Characteristics DIN rail mounting compact module, detachable terminal blocks, LED status indicator for module power and fault alarm.
Working Principle The barrier restricts available energy supplied to field hazardous equipment. Discrete on-off signals are isolated and transmitted to PLC/DCS input channel, while continuously monitoring field wire break fault.
Installation Requirements Mount on DIN rail in non-hazardous control cabinet. Field cable shielding grounded at cabinet side. Comply with intrinsic safety installation standard.
Usage Notes Only install in safe area. Wiring must comply with explosion-proof specifications. Check LED indicator for abnormal field circuit.
