Hi guys,
I'm trying to measure resistance, current, and voltage of a resistor (heater) connected to a 0-24V @ 3A transformer.
The heater's consumption is actually 2A max., and I'd be controlling it with a triac driven with an 8-bit micro, which I'd also use to get the above readings and send them to the host.
This is my initial layout:
As the transformer only has 0-24V output, and I'm using the usual op- amps + shunt configuration, my main worry is that what I've done is actually electrically safe.
Also, any other comments are also very welcome, including suggestions as per the op-amps (part) to use, about the layou itself, etc.
This is the "pseudo-code" I more or less have in mind for it:
Cheers,
