Power Options
Below are two options for powering the AIC+:
• Use the 24V dc user power supply built into the MicroLogix
1200 controller. The AIC+ is powered through a hard-wired
connection using a communication cable (1761-CBL-HM02, or
equivalent) connected to port 2.
• Use an external DC power supply with the following
specifications:
– operating voltage: 24V dc (-15%/+20%)
– output current: 150 mA minimum
– rated NEC Class 2
Make a hard-wired connection from the external supply to the
screw terminals on the bottom of the AIC+.
If you use an external power supply, it must be 24V
ATTENTION
dc (-15%/+20%). Permanent damage results if
miswired with the wrong power source.
