By default Digital Inputs 0..3(, 12..15, 24..27 for SF3) are assigned to Pulse Counts
or Rates 0..3(, 4..11 for SF3). If Microlink-compatible pulse input mapping is
configured in Powerlink then Digital Inputs 9..6(, 21..18, 33..30) are mapped to
Pulses or Rates 0..3(, 4..11).
For RTUs with a
–d
suffix, the Digital Inputs are
internally pulled up to the 12V rail.
The are activated by pulling the input to
GND
via
a switch or relay contact.
