The pCO
2
allows some analogue inputs to be configured as clean digital inputs. The inputs in question are B4, B5, B9, B10. The
inputs must be pre-configured as clean digital inputs by the application software resident in the flash memory. The following
shows the connection diagram:
:$51,1*6: The maximum current delivered by the digital input is 5mA (thus the rating of the external contact must be at
least 5mA). These inputs are not optically-isolated.
