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

Analog Output - Current Mode (4–20 mA)
Requires and external load between 0 and
300 ohm.
Note:
The Analog Output (AO) operates
in the Current Mode when connected to
devices with impedances less than 300
ohm. Devices that exceed 300 ohm may
not operate as intended for Current
Mode applications.
