Function:
The analogue output can be used for stating a process
value. It is possible to choose two types of output sig-
nals 0 - 20 mA or 4 - 20 mA.
If used as a voltage output (0 - 10 V), a pull-down re-
sistor of 500 Ω must be fitted to common (terminal 55).
If the output is used as a current output the resulting
resistance from the equipment connected may not ex-
ceed 500 Ω.
Description of choice:
No function. Is selected if the analogue output is not to
be used.
