Middletown, Pa. — Phoenix Contact offers a family of electronic monitoring relays for single- and three-phase applications. The 22.5-mm wide, DIN-rail mountable modules can be used for monitoring ...

CAMBRIDGE, UK — The miniature SIL HV series high voltage and high current reed relays can switch up to 1000V and carry up to 5A, in an epoxy sealed, single-in-line package measuring only 24×6.4×8.9mm.

The S-PRO 4000 relay provides real-time processing of voltage and current signals with sub-harmonic monitoring at 1 Hz intervals between 5 Hz and 25 Hz (5 Hz, 6 Hz, 7 Hz… 23 Hz, 24 Hz and 25 Hz).

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

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 ...

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 ...

Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...

Anyone who assumes that passive or electromechanical components are simple is either naive or inexperienced. Even a basic, functionally simple component such as a high-power, milliohm current-sense ...
