Description Eight general purpose optically isolated AC digital inputs
(DIN10 to DIN17).
One committed drive enable input (Drive Enable).
The digital inputs DIN10 - DIN17 can be read individually using the associated Mint IN keyword (for
example IN.10) and can be configured for any number of user definable functions. These inputs are
sampled every 15.36ms. If a faster response is required, DIN0~DIN9 on connector X5 can be used.
Each of the AC optically isolated digital inputs has one side connected internally via a current limiting
resistor to the signal on pin 12, CREF. The other side appears as a separate pin on connector X13, for
use by the end user.
