An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

RelayLabTest from OMICRON enables users to assess the overall performance of protection devices under realistic operating conditions. Test signals are calculated on the basis of a network simulation ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

A new series of relays, called Interfacers by developer, Releco, a unit of Turck Inc., are more flexible and have features designed to minimize downtime. Interface relays connect computers and PLC ...

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 ...

Latching relays latch mechanically or magnetically so you don’t have to maintain current running through the coil to keep them on. Latching relays latch mechanically or magnetically so you don’t have ...

A friend once asked about the block of relays pinned to a board behind my car's dash. To him relays were the mysterious little boxes that some cars inexplicably required to operate a horn. More than ...
