Relay Alternative

[[email protected]]

Hi.

I'm building an project to control house devices through PC using
Interface Card from Vellman K8000

I will order SW, which give +5V to Digital output channel this charge
will drive the relay to close, i need another reliable technique
instead of relays somthing that can power high volatge devices such
Air-Condition and it can be signaled through +5V.

Is QBAR good? can it pass 220 volt, or Relays is the only one?
Is relay reliable?

Thanks.

Hello,
I believe a relay or a triac may be used for this.

Why not using TRIAC or Solid State Relays (instead of ElectroMechanical)?

Yes, relays are reliable, they are used for mains swiching all the
time. You do need a proper relay with suitably mains rated contacts
though.

But if you didn't know this already then maybe you shouldn't be
touching mains rated stuff just yet...

If your air-con has an IR remote control then you can control it with
the PC via an IR module - no mains wiring required.
