Shop industrial relays for switching, control, timing, monitoring and equipment-interface applications. Relays allow a control signal to operate another electrical circuit and are widely used in control panels, machinery, automation systems and industrial equipment.
Wallco supplies electromechanical, power, timing and other control relays from established manufacturers. Browse the available relay categories and use technical filters to compare contact configuration, coil voltage, switching capacity, mounting style and other important specifications.
Relays use an electrical control signal to open or close one or more contacts in another circuit. They are commonly used for load switching, electrical isolation, machine sequencing, alarm functions, motor and equipment control, timing and process monitoring.
Important selection factors include relay type, coil or control voltage, contact configuration, contact current and voltage ratings, number of poles, mounting method, terminal style, operating time and expected electrical or mechanical life. The selected relay must also be suitable for the load type and operating environment.
Products are organized generically so relays from different manufacturers can be reviewed within the same product categories and technical filters.
