Power Supply 24 VAC
Note: The numbers between the brackets are the FX16 terminal
numbers.
IMPORTANT: Not respecting the power supply polarity results in a short
circuit causing the blowing of the external fuse.
To achieve isolation from the microprocessor circuits and better
immunity against electrical disturbances, use a separate 24 VAC power
supply to power the analog outputs (terminals 79, 80). See
Figure 52.
