Each opto input can individually be set to a nominal voltage value if custom is selected for
ng. The inputs may be up to 32, depending on MiCOM P54x the global setti number of
model and I/O configuration.

Selects each input with a pre-set filter of ½ cycle that renders the input immune to induced
noise on the wiring. The number of available bits may be 16, 24 or 32, depending on the
