Relays

Keep electronic equipment running well with relay switches. Use relays to control the flow of current when a low-voltage circuit controls a high-voltage circuit. Use relays to help guard against damage within equipment and components by pinpointing abnormalities. Find electronic relays from leading manufacturers at “You-Do-It” Electronic Center for applications ranging from automotive, robotics and variety of do-it-yourself projects. Browse our wide selection of relays and discuss your projects with us to find the best solutions.

New SPARKFUN IoT Power Relay (Voltage Controlled Relay)

SPARKFUN IoT Power Relay (Voltage Controlled Relay), COM-14236

$39.90
Universal control voltage 3-60VDC or 12-120VAC A single input signal switches four outlets: one normally on, one always on, two normally off. Optical isolation, relay hysteresis and de-bounce protection add safety. A large MOV clamps surges for clean 90-140VAC power. The durable SPDT control relay is rated at 30/40A, >400,000 operations at 12A or 2 million+ operations at 5A. A 12A thermal safety circuit breaker switch prevents overloads. Mounting tab with two screw holes Dimensions: 170mm x 95mm x 35mm (6.69in x 3.74in x 1.37in)
