If a 1747-AIC link coupler is connected to the 1747-KE module with a 1747-C11 cable, the link coupler draws
its power (0.085 A @ 24V dc) through the module. Add this to the current listed for the link coupler
requirements.
(3) If a 1747-AIC link coupler is connected to the 1747-KE module with a 1747-C13 cable, then the power for the
link coupler comes from either an SLC 500 controller or an external power supply.
