Topic: arduino + 230V pump + ethernet shield (Read 3 times) previous topic - next topic

Is it possible to make ethernet shield control inputs/outputs over LAN? A website that has buttons for on/off etc?


What would be smart way to control 230V mains with 5V arduino? SSR isnt possible because it has to be NC-relay. If arduino fails etc that relay has to conduct.

Yes

Control outputs:

arduserver.com

Switch 230v:

Use a professionally designed, constructed relay solution, unless you need very rapid on/off switching.

(Thank you! The draft for that has been languishing in my "to do" pile for a long time! You inspired me to get it Out The Door!)

Why arduserver and not arduino + ethernet shield?

this mains socket type aint working for me. Its not gonna be a socket device, its a fixed device, house heater water pump.

How about a small 5V relay to control SSR relay? That way i could have NO operation and i think SSR would be right one for this?

Thre are various relay boards available that are made for use with microcontrollers, parallel ports, etc.
