Only the two unipolar manipulated variable parts are available for selection for outputting to
modulated relays. If outputting the values via a current output, you also have the possibility of
outputting the bipolar manipulated variable y to one current output only (split range).
10.7.2 Alarm relay and optional relays
The basic version of the device always has one alarm relay. Additional relays are also available
depending on the version of the device.
The following functions can be output via a relay:
• Limit switch status
• Controller manipulated variable for controlling an actuator
