High Resolution Counter Input Specifications

Issue

Need to know if the counter input on a xPDI8 meets the 140 hz specification that is called out in the Project Specification.  

Environment

  • xPDI8
  • xPBD4
  • Counter input

Cause

Need to know if the high resolution counter input on a xPDI8 or an xPBD4

Resolution

While the xPDI8 counter input is rated for 140 Hz. this spec is based on a 50% duty cycle rate. 

In any case, the minimum pulse width we can read on a high resolution counter input is 3.57 ms.  Anything less than 3.57 ms cannot be read reliably by the XPDI8.
