Intrinsic Safety Switch Barrier – NAMUR & Contact Input, Relay Output, DIN Rail
Industrial intrinsic safety barrier for interfacing hazardous area switches with control systems. Supports NAMUR sensors and mechanical contacts with relay outputs for PLC and SCADA integration.
This intrinsic safety switch barrier is designed to safely interface field-mounted devices in hazardous areas with control systems located in safe zones. It enables reliable transmission of switch signals while limiting energy to prevent ignition risks in explosive environments.
The unit supports both mechanical contact inputs and NAMUR proximity sensors, making it suitable for a wide range of applications including limit detection, level switching, pressure monitoring, and safety interlocks.
With flexible channel configurations (1 in 1 out, 1 in 2 out, 2 in 2 out), the barrier can be adapted to suit different control strategies, including signal duplication and redundancy. The relay output provides a clean, isolated switching signal for PLCs, DCS, RTUs, and alarm systems.
Designed for DIN rail mounting, the compact form factor allows efficient installation in control panels. Built-in analog and digital indication assists with status monitoring and diagnostics during operation.
