5.7.1.1.2 Technical Data
Binary inputs
12 binary inputs
• 2 groups (with 8 and with 4 inputs)
• Via optocouplers the inputs are galvanical insulated from logi-
cal circuits and ground with double insulation.
• Each group is galvanically insulated from the other group,
from logical circuits and from ground with double insulation
• For each group one common return with selectable polarity
• Function and status of the inputs via display
Filter time 1 dedicated input per group 2 ms
All other inputs 3 ms
