Home Energy Monitor - Rotwang.co.

The ADC requires a low-impedance source of less than 1.5kΩ. Once I'd fixed this and put some 1kΩ pull-ups on the opto isolator, all worked fine. Reading the manual more carefully would have helped here. Here is a photo of the ADC and opto interface during development. No dangerous voltages yet.

How control a relay using the ni usb 6008? - NI Community .

thank you for the reply tom sedlack. I've talked with my teacher and he said me to use a opto-isolator like you are saing to me next I put a transistor working like a switch with a 12Vcc supply hook up to the emitter because the transistor is a pnp and the relay hook up on the colector, but the problem is i don't know how this thing(the opto-isolator with a triac) work.
