ABB numerical relays

Numerical relays are based on the use of microprocessors. The first numerical relays were introduced in 1985.

A major difference between conventional electromechanical and static relays is the way the relays are wired. Electromechanical and static relays have fixed wiring and are set manually. Numerical relays, on the other hand, are programmable relays where the characteristics and behaviour can be programmed. Most numerical relays are also multi-functional.
