russedwards Posted October 22, 2015 Report Share Posted October 22, 2015 Hi guys I've been working on a project so long that I now can't see the solution to what I imagine is a simple problem. I have a v350 and I am taking a digital input to control an MB. I have wired many digital inputs that use the same 24vdc power supply as the PLC.

Alexander Posted October 23, 2015 Report Share Posted October 23, 2015 You should be able to use the same power supply as the PLC as long as it is able to supply current for the whole system. What exactly is the problem? If you measure the input with a digital multimeter how many volts are you reading? Quote Link to comment Share on other sites More sharing options...
