Relay Barriers

Relay Barriers
Intrinsic Safety Barriers is an essential component 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.


EB3C Barriers


The EB3C series provides a cost effective Intrinsic Safety Barriers alternative. Available in 100-240VAC or 24VDC and with from 1 to 16 channels, EB3C series has many options to meet your application.
