ABB Relay

What is ABB Relays ?

Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit.

When a relay contact is normally open (NO), there is an open contact when the relay is not energized. When a relay contact is Normally Closed (NC), there is a closed contact when the relay is not energized. In either case, applying electrical current to the contacts will change their state.

Electronic relays and controls

ABB has the industry’s most comprehensive range of electronic timers, measuring and monitoring relays, interface relays, and power supplies – helping customers source all their critical components from a single global supplier. Increase the reliability of process equipment with control devices that provide intelligent signals and smart adjustments that help you achieve maximum system availability.

h. Relion® 640 series: REX640 All-in-one protection for advanced power generation and distribution applications

i. REX610 is a freely configurable all-in-one protection relay that covers the full range of basic power distribution applications, REX610 represents both a flexible and cost-effective choice.

5. Numerical relays are based on the use of microprocessors, Difference between conventional electromechanical and static relays is how the relays are wired. Electromechanical and static relays have fixed wiring and the setting is manual. Numeric relays, on the other hand, are programmable relays where the characteristics and behavior can be programmed. Most numerical relays are also multifunctional.
