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.
