Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and how they work in cars. You can still find the articles here (Part I: Why We ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

The cost of component failures continues to increase as electronic products become more complex. Most component replacement costs are associated with marginal devices that become intermittent or fail ...

One of the frustrating challenges in integrating systems is interfacing an existing subsystem with a new or different subsystem. In cases where the input/output ...

Use of the powerful event reports can increase system reliability, lower maintenance costs, and reduce the potential for system damage and resulting outages. Today’s microprocessor-based relays ...

Part of any self-respecting Smart Home, smart relays are useful for switching and monitoring loads that do not plug into an outlet. This also makes them a lot more integrated, and thus, a long ...

When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

Many low and medium temperature single-phase compressors require some type of external relay to assist in the starting of its motor. The purpose of this relay is to remove the motor’s start winding, ...
