PrIO configured as output
NOTE
: For the location of the PrIOs in the various devices see
The electrical outputs can be individually configured as:
•
“ s v p s " p , p v g V
⎓
.
•
“ p s v " p , w v s v g (p -free output).
Electrical outputs can be used to control relays (the relay coil must operate at 12 V
⎓
and require no more
current than the output can supply) or LEDs. Two relays in series can be used to control large loads.
The following diagrams are valid for an electrical output with positive reference and programmed as "no
positive".
