Relays & Contactors
Switching devices that let a small control signal operate larger loads. The category spans power relays, signal relays, interface relays, timer relays, monitoring relays, contactors and solid state relays, as well as motor protection parts. Pages are grouped by function, so general purpose relays, timing and monitoring units, motor starting parts and solid state types are easy to compare.
They sit in control panels for motors, heaters, lighting and machine sequences. Check the coil voltage, the contact or switching rating, the number of poles and the choice between mechanical and solid state switching for the duty.
- Starting and stopping electric motors
- Delay timing in machine sequences
- Interfacing PLC outputs with field loads
Browse by type: Power, Signal & Interface Relays, Timer & Monitoring Relays, Contactors & Motor Protection, Solid State Relays.
