The Relay Plug is a small board containing two miniature relays for loads up to 3A @ 120V (both AC and DC).
This plug was designed to switch low-voltage lights, motors, fans, and… larger relays. It provides fully isolated contacts, i.e. there is no electrical connection between the switched connector pins and the rest of the circuit.
This plug could be used to switch AC mains power up to about 250W @ 110V. You should only consider
this if you know exactly what you’re doing, and have taken all the necessary safety precautions. High voltages can be lethal – proceed at your own risk!
This is JeeLabs relay board v1 and slightly different than the relay board that JeeLabs is selling currently. The redesign was necessitated by the unavailability of the miniature relays. We waited a long time to get our hands on these relays.
The Assembled Relay Plug comes with the surface mount driver chips already soldered-on, including terminal blocks. Our terminal blocks are more traditional one-piece terminal blocks. Headers for this and all other JeeLabs plugs can be found here (straight) and here (right angle). We’ll update the photos soon.
The PCB Only version contains just the printed circuit board for the Relay Plug. No parts, no headers.
