CHAPTER 3: CONNECTING TO DEVICES AND NETWORKS SUPPLYING POWER THROUGH THE D.20 LINKD.20 RIO - HARDWARE USER’S MANUAL GE Information 33Supplying power through the D.20 LinkPower is typically supplied to peripheral devices directly through the WESTERM boards.However, you can configure the D.20 RIO to supply peripheral devices with power throughthe D.20 ports. In systems with more than five peripherals, an external power supply andD20 DC interface module (520-0154) are required.The Auxiliary terminals and/or power through the D.20 port should not be loaded byperipherals to exceed 165 W.Table 11: Typical power consumption for D20 I/O modulesConnect power to D20A, D20S, D20K, and D20C peripheral boards through the D.20 HDLCLink using a daisy-chain series of connections from peripheral to peripheral.To power peripheralsthrough the D.20 Link:1. Ensure JP1is set correctly for your peripheral devices. See “JP1: Power supply to D.20connectors” on page 23.2. Connect the D.20 link DB9 connector to the J1 input on WESTERM peripheral boardnumber one.3. Connect the D.20 link DB9 connector from the J2 connector and into the J1 connectoron WESTERM peripheral board number two.4. Repeat steps 2 and 3 for each WESTERM peripheral board in series.Result: The peripherals are now connected for power using the D.20 Link.EthernetThe D.20 RIO can connect to one or two networks through two Ethernet connections.Within the operating system of the D.20 RIO, LAN A is assigned to Ethernet interface eth0and LAN B is assigned to Ethernet interface eth1. The interfaces eth0 and eth1 can also bebonded for redundant operation.All RJ-45 connectors have the same signal definition. However, the Ethernet ports are autoMDI/MDIX and can support a straight-through or crossover cable.To connect the D.20RIO to networkdevicesPlug network cables into the D.20 RIO Ethernet ports.The D.20 RIO is intended to be used on a secure LAN behind a firewall. It is not designed tobe used as a gateway device.The D.20 RIO is intended to be used in a 10/100 Mbps network; the D.20 RIO does notcommunicate on a dedicated 1Gbps network.D20 I/O Module Power ConsumptionD20A 20 to 60 VDC, 8 W typicalD20C 20 to 60 VDC, 5 W typicalD20K 20 to 60 VDC4 W typical, 11 W with all relays energizedD20S 20 to 60 VDC, 4 W typical
