4–20mA Intrinsic Safety Barrier – Analog Signal Isolator & Hazardous Area
Intrinsically safe 4–20mA signal isolator for transmitting analog signals from hazardous areas to control systems. Provides electrical isolation, noise immunity, and safe operation in explosive environments.
This intrinsic safety barrier is designed to safely transfer 4–20mA analog signals from field devices located in hazardous areas to control systems installed in safe zones. It acts as a signal isolator while limiting electrical energy, ensuring compliance with intrinsic safety requirements and preventing ignition risks.
Commonly used with transmitters such as pressure sensors, level sensors, and temperature transmitters, the unit provides stable and accurate signal transmission to PLCs, RTUs, DCS, and SCADA systems.
The device delivers galvanic isolation between input, output, and power supply, improving system reliability and protecting control equipment from electrical noise, surges, and ground loops.
With a compact DIN rail design and clear status indication, it is easy to install and maintain within industrial control panels.
