ION7330 digital I/O module pulse count
Issue:
The digital input is triggering the digital output with counters on each to keep track of pulses, the pulses start to show a discrepancy.
Product Line:
ION 7330
Environment:
ION 7330 I/O pulsing module
Cause:
The Digital Output module on the 7330 meter is a one-second module, meaning that it only updates once per second. As such, it would be expected to lose pulses on the output if they are around 1 Hz or more. The Digital Input module is also a one-second module; however, the transition detection and trigger output occurs much faster so it is able to properly count pulses with an attached counter module.
Resolution:
This is the design of the ION 7330 digital I/O module. Consider using the pulse count from the input or route the original pulse to the second device that needs the pulse.
