Dear Abyrne, The probelm could have come from yourwiring You may want to try this out:- 1]disconnect all output wiring and left with the supply wiring to the SM422. 2] Then connect back the wiring one by one to the card channel and measure see which one gives you the residual voltage. Hope this helps. with regards, how come? |

Hello, In the technical sheet of the SM422 you see that even with a "0" status, the board may deliver a residual current of 0.5 mA. I believe that if you connect only a very high impedance (like a voltmeter where the input resistancemust be very high, several MegOhms) you could measure a high voltage. If you conenct like you did a usual consumer (whichhas only a fewhundreds of Ohm or less), themeasured voltage drops. |
