Hi all,
I have been asked by the company to work for to design a test box for the products they sell.
The products I am testing can be run from 230V, 110V, 24V or 12V AC, I must explain this bit each product can only run from one of those AC voltages, but the test box must be able to supply any of those voltages to the product, as if I was to have 4 test boxes (1 for each voltage) I wouldn't be asking this question now.
So far I have the transformers to convert from 230v to the other 3 voltages and I have 4 relays to switch these voltages to the product. What I need to do is now come up with some way that when the product switches the input voltage I can detect it back in the test box.... Confused ???
The product I am testing has it's own relay that will switch it's input voltage (230,110,24,12V AC) I need to test that the relay is working correctly by check that I am getting a voltage back from the product.
So far I have a PIC controlling the 4 first relays and I was sort of thinking that I might have another 4 relay to switch the incoming voltage... would that work ????
Also I need to convert the 4 incoming voltages to 5V DC so that I can fed that into my PIC.... That is going to be hard? right ???
Please some one help me.
Thanks in advance
Chris
