Barriers

Intrinsically Safe Relay Barriers are essential components of intrinsically safe applications. These devices limit current, voltage, & total energy delivered to a sensor or any other actuator instrument located in a hazardous area. When used in areas with hazardous chemicals, gases or other ignitable atmospheres, limiting the energy is required to prevent any possible fires & explosions from occurring. Dry contact switches can be connected to the EB3C. Illuminated switches also can be connected with the combination of the EB3S Relay and the EB3L Lamp Barriers.

For building safety systems in explosive atmospheres

Various types of pilot lights and buzzers can be connected and used in Zone 0 areas. Illuminated pushbuttons and illuminated selector switches can be connected by combining with the EB3C relay barrier.

The EB3S series enables sensors installed in hazardous areas to be safely connected to PLCs and control systems located in safe areas. Specifically designed for 3-wire photoelectric sensors, it simplifies system integration while helping ensure installation compliance. With different channel configurations, AC or DC power supply options and a compact design, the EB3S series provides a flexible solution for industrial applications subject to ATEX and IECEx requirements. EB3S barriers are compatible with SA2E-EX sensors. This combination is internationally EX-certified for safe use in hazardous environments.
