Relays are electrically-operated switches that regulate power to downstream circuits when energized to control low-current equipment, devices, machinery, and electrical systems.
- General purpose and power relays use input signals and low voltages to control larger circuits.
- Time-delay relays open and close their contacts at preset times.
- Monitoring relays detect changes in operational or environmental conditions and protect downstream equipment from damage.
- Safety relays monitor operational and environmental conditions and disrupt power to protect workers.
- Solid-state relays have no moving parts and provide long service lives.
- Alternating relays toggle between loads to sequence load matching and distribute equal run times.
- Automotive relays regulate the flow of power through circuits to control vehicle components.
- Relay sockets mount on surfaces to interface relays with electrical connections.
