Output characteristics
Defines the shape and up to 5 break points of an analogue output. For intrinsic-error for analogue
outputs with bent or linear zoom characteristic multiply accuracy class with correction factor (c).
Correction factor c (the highest value applies):

Example of settings with linear and bent characteristic:
Average interval for analogue output
Defines the average interval for measurements on the analogue output. Available settings are
from 1 period (0.02 sec by 50 Hz) up to 128 periods (2.56 sec by 50 Hz).
Fast analogue output
Functionality of the fast analogue output module is the same as with the standard analogue output
module.
The only difference is its faster response time (≤ 50 ms), and consequential higher ripple. For a
proper behaviour of the fast analogue output module (fast response), the average interval must
be set to minimum (1 period).
Relay output module
Relay output module can be assigned different functions.
− Alarm notification functionality (alarm output)
− Pulse output for energy measurement (pulse output)
− General purpose digital output (digital output)
