Power Options
Below are two options for powering the AIC+:
•
Use the 24V dc user power supply (200 mA maximum) built into the
MicroLogix 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 +20% / –15%
– output current: 200 mA maximum
– rated NEC
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 dc. Permanent damage
will result if miswired with the wrong power source.
Installing and Attaching the AIC+
1. Take care when installing the AIC+ in an enclosure so that the cable connecting
the MicroLogix 1000 controller to the AIC+ does not interfere with the
enclosure door.
2. Carefully plug the terminal block into the DH-485 port on the AIC+ you are
putting on the network. Allow enough cable slack to prevent stress on the plug.
3. Provide strain relief for the Belden cable after it is wired to the terminal block.
This guards against breakage of the Belden cable wires.
