The outputs A, B, C and D may be either short or open-
circuited. They are electrically insulated from each other and
from all other circuits (floating).
System response
Duration of the
measurement cycle: Approx. 0.5 to 1.2 s at 50 Hz,
depending on measured variable
and programming
Response time: 1...2 times the measurement cycle
Accuracy class: (the reference value is the full-scale
value Y2)
