Relays

Relays

Electromechanical relays are just one type of electronic switch used in industrial control systems. A relay is simply an electrical switch. The electricity operating the switch is fully isolated/insulated from the electricity/circuit being operated. Electromechanical relays, unlike other types, use an electromagnet to move the switch mechanically. While solid state relays use a semiconductor to switch. There are many other types including: pole and throw, overload protection, latching, forced-guided, contactor and solid state contactor. Still people are drawn to the solid state relay because it has no moving parts making its installation more reliable than others. When choosing from an electromechanical relay and other types consider these factors: • number of contacts • normally open, normally closed • contact sequence • rating of the contacts (voltage and amperes) • operating lifetime • coil current / voltage • enclosure type • operating environment • mounting configuration If you have questions about electromechanical relays or other equipment contact a Davis Application Specialist today.
