I am using a K8055 with the iphone app to control various low voltage switches in my house. It works great. I would now like to switch some mains-powered devices on and off. What hardware do I need to be able to do this, e.g. a simple example - I have a table lamp which I want to switch on and off from the K8055 board. Is there a pre-built module or relay etc that would allow me to do this? I am based in the UK.
These Velleman relay cards can be used with the K8055 board:
UNIVERSAL RELAY CARD K6714
velleman.eu/distributor/prod … w/?id=9358
RELAY CARD K2633
velleman.eu/distributor/prod … w/?id=9069
External 9V power supply is needed.
8-CHANNEL RELAY CARD VM129 (module)
velleman.eu/distributor/prod … ?id=361120
8-CHANNEL RELAY CARD K8056 (kit)
velleman.eu/distributor/prod … ?id=351282
External transformer 12Vac / 500mA is needed.
Connection to the K8055 card is very simple:
- Connect the control input terminals of the relay card to the digital outputs of the K8055 card.
- Connect the GND terminal of the relay card to the GND terminal of the K8055.
Please see this manual p.12 how to connect the load (e.g. table lamp) to the relay output terminals:
