The PSR-MXF multifunctional safety relay is the newest addition to the Phoenix Contact PSR safety relay line. This relay can help small and medium machine builders reduce cost and save space. The ...

LG5924 Series relays are single-channel E-stop relays designed to protect people and machines in applications with emergency stop buttons. Available with 24 VDC, 110 VAC, and 230 VAC coil voltages, ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

Factory equipment continues to become increasingly intelligent in large part due to the improved processing power and communication abilities found within underlying controllers, sensors, and ...

If you're curious about the function of a relay in the context of home automation and the Internet of Things, here you go. In this piece, we'll explain the practical applications of many different ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

Before the 1990s, most safety precautions were handled by external hardware such as contactors, relays, and switches. Emergency stops were used to physically remove power from drives and controllers.
