Barriers

3 Series
Intrinsic Safety Relay Barriers are essential components of an intrinsically safe application. 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.
