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 ...

Pickering Interfaces has announced a range of PXI and PXIe microwave relay modules capable of switching signals up to 110GHz in 50Ω. They will be reveals for the first time at IMS in San Diego next ...

With its ease of configuration and its comprehensive range of facilities, including a variable-frequency voltage source with a continuous phase-shift function, Megger’s new self-contained SVERKER 780 ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

A switch-matrix board that routes any of eight programmable voltage signals to any of 96 output pins. The board generates digital patterns up to 20 MHz and 30 kV and has 36 Mbytes of memory. Four ...
