New to analogue I/O's. I have seen 4 to 20 mA inputs and the ladder programme that this represents (I think). The 4 ma is 3424 and the 20 mA is
16528 (from memory) can check these numbers later. Can anyone tell me how we arrive at three thousand and odd and the sixteen thousand and odd. Is this some equivalent for the 4 to 20? What would this number be for say 12 mA? TIA
