(2)

If a 1747-AIC link coupler is connected to the 1747-KE module with a 1747-C11 cable, the link coupler draws its power
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.

IMPORTANT

The interface module receives its power from the SLC backplane.
The power consumption of the module must be taken into
consideration when planning your SLC 500 system. Refer to the
documentation supplied with your SLC 500 fixed or modular
controller for additional information on power supplies and
current requirements.
