Explosion-Proof Switch Signal Isolator – Intrinsically Safe Barrier, Hazardous A
Intrinsically safe signal isolator designed to transfer switch signals from hazardous areas to safe zones. Provides electrical isolation, safety compliance, and reliable interfacing with PLC and control systems.
This explosion-proof switch signal isolator is designed for safe transmission of digital (on/off) signals from hazardous areas into safe control environments. Commonly used in industrial plants handling flammable gases, vapours, or dust, the unit acts as an intrinsic safety barrier, limiting energy transfer to prevent ignition risks.
Installed within the safe area, the device interfaces with field-mounted switches such as limit switches, float switches, pressure switches, and proximity sensors located in hazardous zones. It provides galvanic isolation between input and output circuits, ensuring both system protection and signal integrity.
The isolator supports reliable signal transmission to PLCs, DCS, RTUs, and SCADA systems, making it suitable for oil & gas, chemical processing, mining, fuel storage, and manufacturing environments.
With a compact DIN rail design and dual analog/digital indication, it allows easy installation, monitoring, and diagnostics within control panels.
