No matter what the application is, when a definite-purpose solution is required, time delay relays (TDRs) can provide simple, reliable, and economical control. Adjusting the delay time is often as ...

This is a simple circuit which I built to one of my audio amplifier projects to control the speaker output relay. The purpose of this circuit is to control the relay which turns on the speaker output ...

LIBERTY, S.C. – The REL-32.PCI, a 32-output digital I/O interface for the PCI bus, has been added to the Sealevel Systems Inc. product line. The unit provides 32 reed-relay outputs, which can be used ...

Recently, [Manuel] did a post on making logic gates out of anything. He mentioned a site about relay logic. While it is true that you can build logic gates using switch logic (that is, two switches in ...

Addressing the requirements of power switching applications, the ADAM-6066 relay-output module includes Ethernet connectivity, an embedded web server for remote monitoring, and support for Modbus/TCP ...

Inspired by input from panel builders, system integrators and end users around the world, Rockwell Automation engineers developed the new Allen-Bradley E300 electronic overload relay. The E300 ...

Designed for high-voltage protection in industrial control and monitoring applications, the PCIe-IDIO-24 PCI Express I/O card boasts 24 optically isolated digital inputs and 24 solid-state FET relay ...

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 ...

IXYS Integrated Circuits Division, now part of Littelfuse, Inc., today introduced the CPC1984Y, a 600V, Normally Open Power SIP Relay, rated for up to 1A DC/1Arms continuous load current, twice the ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.
