Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...

Interface relays connect computers and PLC logic devices to machines. But conventional block, modular terminal strips, and socket I/O relays are difficult to modify, and require hours of downtime for ...

IEC 61850 is the new international communication standard for substations. The main goal of 61850 is to obtain interoperability between different protective devices from different vendors. IEC 61850 ...

The 78 series 10-A relays are available with a variety of options, including a push-to-test button and a green LED status lamp. The ice-cube-style industrial relays use quick-connect, plug-in/solder ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...
