Bottom V iew
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.
In normal operation with the MicroLogix 1000 programmable controller connected
to port 2 of the AIC+, the controller powers the AIC+. Any AIC+ not connected to
a controller requires a 24V dc power supply. The AIC+ requires 104 mA at 24V dc.
If both the controller and external power are connected to the AIC+, the power
selection switch determines what device powers the AIC+.
