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.

5.3.5.1BPL010-502 - 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 5mA in the input circuit. To ensure that an input becomes inactive, the current must be less than 1mA. The internal pull-up resistor on the NextMove ES allows the input to be left floating when inactive or not being used.
