Technical Specifications Signal Type: 4‑20mA analog signal Intrinsic Safety Level: Meet industrial explosion‑proof standard Mounting: DIN rail mounting Operating Temperature: ‑20℃ ~ +60℃
Functional Features Galvanic isolation between hazardous area and safe area. Limit output energy for explosion‑proof requirement. Pass‑through analog loop signal without signal distortion. Provide circuit over‑voltage and over‑current protection.
Application Scenarios Chemical plant hazardous area instrument signal, oil & gas field control system, power plant explosive‑risk workshop signal isolation.
Performance Parameters Signal transmission accuracy: Low signal attenuation Isolation voltage: High dielectric isolation strength
Structural Characteristics Compact plastic housing, DIN rail snap‑on structure. Screw terminals for field wiring.
Working Principle Adopt isolation transformer and energy‑limiting circuit. Restrict maximum voltage and current output to field hazardous side, meanwhile complete analog signal transmission.
Installation Requirements Install in non‑hazardous safe zone cabinet. DIN‑rail fixed firmly. Wiring strictly follow intrinsic safety installation specification.
Usage Notes Cannot install module inside explosive hazardous zone. Strictly match field intrinsic safety instrument parameters.
