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.

Intrinsic Safety is to limit the voltage and current so that there is never a spark with enough energy to create an explosion. Intrinsically Safe Safety Barriers are essential components of intrinsically safe applications. IDEC has combined the elements of an intrinsic barrier with those of a safety device to create the first intrinsically safe machine safety barrier. 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. A total safety system can also be built by connecting safety control devices such as safety relay modules and safety controllers with the EB3N.
