Relay Plug

€2.50 - €15.00

The Relay Plug is a small board containing two miniature relays for loads up to 5A @ 250V (both AC and DC) - note that the previous relays were smaller but only handled 3A.

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.

In theory, this plug could be used to switch AC mains power (over 1000W @ 220V and 500W @ 110V). In practice, 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!

The Pre-assembled version comes with all the parts needed and the SMD driver chips already soldered-on, including a high-power terminal block with individually detachable connectors. Note that no 6-pin headers are included.

The PCB only variant contains just the board for the Relay Plug. No parts, no headers.

As connectors you can use a Plug Headers set with 10 male and 10 female 6-pin headers, which makes it easy to connect multiple plugs and JeeNodes in a “standard” way. Or you can solder the board directly in place for more permanent use.

The documentation and full design details are freely available.

Note: new relay boards are in, using lightly different relays, same 5A ratings.
