4-18 Communication Connections
Set the DC Power Source selector switch to EXTERNAL before connecting
the power supply to the AIC+. The following illustration shows where to
connect external power for the AIC+.
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+.
ATTENTION
Always connect the CHS GND (chassis ground)
terminal to the nearest earth ground. This connection
must be made whether or not an external 24V dc
supply is used.
ATTENTION
If you use an external power supply, it must be 24V
dc (-15%/+20%). Permanent damage results if
miswired with the wrong power source.
