Connection of the 4 configurable analog outputs
Connector / Terminal Pin Assignment / Signal
X10 / AG.2 75 AGND2
X10 / 3.5 76 DA502 / AO0+
X10 / 3.6 77 DA502 / AO1+
X10 / 7.5 78 DA501 / AO0+
X10 / 7.6 79 DA501 / AO1+
UP must be connected to connectors X7, X8 and X9. The internal voltage
supply to the ADC channels is no longer provided by L+ but by UP in the mod-
ules DA501 and DA502.
The arrangement of the 4 analog outputs is shown below:

Resolution: 12 bit (+ sign)
The 4 analog outputs are not electrically isolated and have a reference to ZP internally via PTC
resistors.
