Explosion-Proof 4–20mA Intrinsic Safety Barrier – Analog Signal Isolator, Hazard
Intrinsically safe 4–20mA signal isolator for hazardous area applications. Provides reliable, isolated signal transmission from field devices to PLC and control systems.
This explosion-proof intrinsic safety barrier is designed to safely interface 4–20mA analog signals between hazardous area field devices and control systems located in safe zones. It limits electrical energy entering hazardous environments, reducing ignition risk while maintaining accurate signal transmission.
Commonly used with pressure transmitters, level sensors, and temperature transmitters, the unit ensures stable and noise-resistant signal transfer to PLCs, RTUs, DCS, and SCADA platforms.
The device provides full galvanic isolation between input, output, and power supply, improving system reliability and protecting equipment from electrical interference, surges, and ground loops.
With a compact DIN rail form factor and integrated status indication, it is well suited for installation in industrial control panels across oil & gas, chemical, mining, and process industries.
