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.

Intrinsic Safety Lamp Barriers are essential components of an intrinsically safe application. These devices are to limit the voltage and current to prevent ignition in hazardous areas. 126 different types of pilot lights and buzzers can be connected. Illuminated push buttons and selector switches also can be used with the combination of EB3L lamp and EB3C relay barriers.

By connecting safety input devices such as emergency stop push buttons and safety interlock switches to the EB3N intrinsically safe safety barrier, in conjunction with a contactor in conformity of safety standards, both intrinsic safety and machine safety can be established simultaneously in a hazardous location.
