Chapter 2 Installation and Configuration©National Instruments Corporation2-9FieldPoint FP-3000 User ManualConnect Power to the FP-3000An 11–30 VDC power supply is required by each FP-3000 on yournetwork. The FP-3000 filters and regulates this supplied power andprovides power for all the I/O modules in the bank. Therefore, you do notneed to provide power separately to each FieldPoint I/O module inthe bank.The power connector is a 6-pin screw terminal power connector whosepinout is shown in Figure 2-10. See Figure 2-11 for the location of thepower connector.Figure 2-10. FP-3000 Power Connector PinoutConnect the primary power supply to the center V and C pair with thepositive and negative wires on your power cable in the V and C terminals,respectively. You can connect an optional backup power supply to the leftV and C pair. The right V and C pair provides a convenient means ofconnecting power to the V and C terminals of a terminal base. Figure 2-10shows this optional connection.If your field I/O devices need to be powered separately, you can use theterminals provided on each terminal base for such power supplyconnections. Refer to the documentation that came with your terminal baseand I/O module for more information on powering your field I/O devices.Calculating Power for a FieldPoint BankThe power requirements for a FieldPoint bank that uses an FP-3000network module are calculated as follows:Power = 6 watts + 1.15 * ∑(I/O Module Consumption)v v vc c c11-30 VDCBackup PowerSupply(optional)+–+–11-30 VDCPrimary PowerSupplyVCTo adjacent device(optional connection)
