This breakout module gives you access to a 4 channel solid state relay that can be switched with 3-5VDC






Single-channel WisBlock relay switches up to 250 VAC/10 A for control of motors, lights and conveyors in IoT projects.


Bring programmable switching to a DIN rail - high-power relays, isolated field inputs and a wired network connection in one unit.




Your 5V system can wield great power with this big, beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!



DIN rail mount for DPDT Relays with screw terminals.







Z-Wave relay with two NO/NC outputs and dual dry-contact 12-24V inputs to control DC up/down motors, sprinklers and gates.
