Analog Output - Voltage Mode (0–10
VDC)
10 VDC maximum output voltage
10 mA maximum output current
Required an external load of 1,000 ohms
or more.
Note:
The Analog Output (AO)
operates in the Voltage Mode
when connected to devices with
impedances greater than 1,000
ohms. Devices that drop below 1,000
ohm may not operate as intended
for Voltage Mode applications.
