5.3.5 Digital inputs 16-19
The BPL010-502 and BPL010-503 opto-isolating cards use different input configurations.
Sections 5.3.5.1 and 5.3.5.2 describe the two input types.
5.3.5.1 BPL010-502 - Active high inputs
The user power supply connection USR GND is common to all inputs. To activate an input, a
voltage must be applied that is sufficient to cause at least 5 mA in the input circuit. To ensure
that an input becomes inactive, the current must be less than 1 mA. The internal pull-up
resistor on the NextMove ES allows the input to be left floating when inactive or not being
used.
