Output range
Defines the shape and up to 5 break points of an analog output. For intrinsic-error for analog
outputs with bent or linear zoom characteristic multiply accuracy class with correction factor (c).

Example of settings with linear and bent characteristic:
Average interval for analog output
Defines the average interval for measurements on the analog output. Available settings are from
1 period (0.02 sec by 50 Hz) up to 128 periods (2.56 sec by 50 Hz).
Fast analog output module
Functionality of fast analog output module is the same as with standard analog output module.
The only difference is its faster response time (≤ 60 ms), and consequential higher ripple. For a
proper behavior of fast analog output module (fast response), average interval shall be set to
minimum (1 periode).
Solid state output module
See Relay output module.
Relay output module
Relay output module as well as Solid state 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)
