Table 23: Technical data - analog outputs
Note!
Since the analog outputs are fed from the central PiXtend V2 -L- supply
voltage (12 - 24 V), the following must be observed: The nominal output
current of 10 mA per channel can only be taken when the PiXtend
module has a min. 13.5 V supplied.
** Deviations up to 2% (relative to the scale end value) are possible under EMC exposure.
