Intelligent Technologies QCPort System Install ManualNovember 2005MN05001002E For more information visit www.eatonelectrical.com Page 8Multiple Peripherals on One Device Using QCPortQCPort has been designed to support multiple devices connected to one motorcontroller, without the motor controller having prior knowledge of the connected device.Devices that can be connected to a motor controller include user interface products andIO products. Once again, the devices are connected to Channel 0 of the motor controller.The figure below illustrates an application example that includes a user interface and IOmodules. The input module is used to apply a hard-wired HOA while the output moduleis used to annunciate the motor controller status and trip conditions. The mapping of thedata between the motor controller and the IO devices does not require a tool and isseamless to the user.Figure 2: Example of Multiple Peripherals on One Device Using QCPortWhen multiple devices are connected to one motor controller, the user has to be aware ofthe power demand of all of the peripherals. Verify the power requirement of this systemby adding up the power demands of the peripherals to see if they exceed the powercapacity of the motor controller. If the power capacity of the motor controller is exceeded,a power supply is required for QCPort. To help size the power supply, consult “Locatinga Power Supply” later in the manual.
