Ambient Shipping and Storage
Conditions
Temperature: -40 to 80C (-40 to 176F)
Humidity: Up to 95% RH noncondensing; maximum dew point 29C (85F)
Analog Output Voltage Mode (0 to 10 VDC):
10 VDC maximum output voltage
10 mA maximum output current
Requires an external load of 1,000 ohms or more
The AO operates in Voltage Mode when connected to devices with impedance greater than 1,000 ohms. Devices that
drop below 1,000 ohms may not operate as intended with Voltage Mode applications.
Current Mode (4 to 20 mA):
Requires an external load between 0 to 300 ohms
The AO operates in Current Mode when connected to devices with impedances less than 300 ohms. Devices that
exceed 300 ohms may not operate as intended with Current Mode applications.
Control Construction Independently mounted control, surface mounted with Lexan® 950 enclosure suitable for DIN rail mounting or direct
mounting to a hard, even surface.
