Hi
Will HDBB2 inputs work with a 5V encoder like the AMT103

Thanks,
Derek

Hi Derek,

Not really, the problem is that the HDBB2 has slow optocouplers and filtered inputs, so the input signals delays so much that it cannot throughput the high frequency of encoders.
The UCSB and UCBB breakout boards using fast optocouplers with minimal filtering, they can be used to interface encoders.

Thanks that's what I figured.
