The following definitionsapply throughout this section:• Sourcing a Digital Input - The digital input common(return) is connected to the power supply common.Applying a positive voltage to the digital input willcause it to activate (pull up).• Sinking a Digital Input - The digital input common(return) is connected to the power supply positivevoltage. Applying 0V or common to the digital inputwill cause it to activate (pull down).• Sinking a Digital Output - The digital outputcommon (return) is connected to the power supplycommon. The device to be controlled by the digitaloutput is connect to the positive voltage and thedevice common is connected to the digital output.• Sinking a Digital Output - The digital outputcommon (return) is connected to the power supplypositive voltage. The digital output is connect to thedevice to be controlled and the device common isconnected to the power supply common.Note:Digital Inputs 1-3 can only be configured as sourcinginputs. Digital Inputs 4-6 can be configured as sourcing orsinking inputs.Sinking Digital Output - Internal Power SupplyCom1234567824V dc
