Intrinsically Safe Barrier Relays

Barrier Relays vs. Zener Barriers in Intrinsically Safe Control Circuits

Tuesday: September 3, 2019

Intrinsically safe control circuits provide a safe and cost-effective method for interfacing electrical control devices that span across hazardous and non-hazardous locations. Safety is ensured at these interfaces using intrinsically safe barrier devices.

Circuit Design for Intrinsic Safety

Wednesday: August 14, 2019

When installing electrical equipment in or near hazardous locations, specific circuit design principles must be followed in order to prevent an explosion.

Understanding Entity Parameters

Monday: July 15, 2019

When designing Intrinsically Safe Circuits, it is imperative to understand the entity parameters of the devices in your circuit. The entity parameters describe characteristics of the device, as well as what can safely be connected to it.

Why UL 913 8th Edition Certification Matters?

Thursday: June 20, 2019

Intrinsically Safe devices are not yet required to meet UL 913 8th Edition. So why does certification to the more stringent 8th edition matter?

An Overview of Hazardous Locations

Thursday: May 23, 2019

When electrical equipment is used in, around, or near an atmosphere that has flammable gases or vapors, flammable liquids, combustible dusts, ignitable fibers or flyings, there is a possibility or risk that a fire or explosion might occur.
