Blitz Posted March 13, 2011 Report Share Posted March 13, 2011 Hi all, What is the maximum switching frequency for inputs 0-14 of IO-DI16 module? I need to totalize several low frequency pulses (e.g., around 100 to 200 Hz) and would like to confirm suitability of the normal digital input channels.

MVP 2014 Simon Posted March 13, 2011 MVP 2014 Report Share Posted March 13, 2011 From the datasheet, the response time is 10ms on all inputs, except for input15 when it is confiugred as a High-Speed input. I had to read it a couple of times to be sure, and from the wording of your questions, sounds like you had the same issue. Quote Link to comment Share on other sites More sharing options...
cantcliff Posted September 8, 2014 Report Share Posted September 8, 2014 To clarify, 10ms = 100Hz best case, assuming no scan delays. Beyond that you need to use high speed input/counter. Quote Link to comment Share on other sites More sharing options...
