Operation
Description
Timing
Input file update time
The delay between the time the module receives a pulse and when the Compact bus
count value is updated.
500 µs, max
Output turn-on time
The time it takes for the real output to reach 90% output voltage after commanded by
the module, not including processor scan time.
400 µs, max
Output turn-off time
The time it takes for the real output to reach 10% output voltage after commanded by
the module, not including the processor scan time.
200 µs, max
Rate accuracy
The accuracy of the reported rate as compared to actual input rate in the equation:
reported rate/actual input rate.
Depends on frequency.
