Product Overview

System 450™ Series Modular Controls Product Bulletin 19
Analog Output Voltage Mode (0–10 VDC):
10 VDC maximum output voltage
10 mA maximum output current
Requires an external load of 1,000 ohm or more
The AO operates in Voltage Mode when connected to devices with impedance greater
than 1,000 ohm. Devices that drop below 1,000 ohm may not operate as intended with
Voltage Mode applications.
Current Mode (4–20 mA):
Requires an external load between 0–300 ohm
The AO operates in Current Mode when connected to devices with impedances less
than 300 ohm. Devices that rise above 300 ohm may not operate as intended with
Current Mode applications.
Analog Input Accuracy Resolution: 14 bit
Control Construction Independently mounted control, surface mounted with Lexan® 950 enclosure suitable
for DIN rail mounting or direct mounting to a hard, even surface.
