4.1.2 Center Winder Option Terminals

The figure below shows the five green terminal strips on the MCO 305 Option Card. The 24V supply on the digital input and output terminal strips are
internally connected to the VLT Automatio24V supply available at terminals 12 & 13. The COM is connected to VLT AutomationDrive terminal
39. An external 24 VDC power supply can be used. See the MCO 305 Instruction Manual for details on setting MCO Supplied by external 24 VDC (parameter
33-85). The isolated 5V/400mA and 8V/250mA encoder supply is generated on the MCO 305 Card from the 24 V power supply.
