5.16 Connecting loads/actuators to current outputs
Connecting loads to current outputs
Always connect loads to Q
I
and to the reference point of analog circuit M
ANA
of a current output.
Note
The cables required to connect the analog output module are not drawn in the figure shown
below.
In other words, you must continue to read and follow the instructions in the section "Connecting
loads/actuators to analog outputs", which contains general information on connecting sensors.
