? IC694PWR331: Serial Expansion Power Supply, 24Vdc, High Capacity ? Module Hot Insertion and Removal are NOT permitted on Expansion Backplanes. ? Each Expansion Backplane has a Rack Number Selection DIP switch (Figure 18) that must be set before module installation. ? Each Expansion Backplane has a Bus Expansion connector at its right end for attaching an optional expansion cable. There can be no more than 50 feet (15 meters) of cable connecting Expansion backplanes with the Universal Backplane. If the system includes Series 90-30 Remote Backplanes, the additional requirements summarized in Section 1.3 through Section 1.5 must also be observed. Universal Backplane Expansion Backplane Up to 15 meters (50 Ft) Expansion Backplane I/O Bus Terminating Resistor Expansion Backplane Expansion Backplane Figure 76: Example RX3i System with Expansion Backplane Racks PACSystems* RX3i System Manual Section 5 IC694 Power Supplies, which must be used in RX3i Serial Expansion (IC694) Backplanes. Individual power supply specifications are listed in the following sections. The IC695 Power Supplies provide up to 40 W each. The IC694 (Expansion) Power Supplies provide up to 30 W each. However, IC694PWR321 is limited to 15 Watts on the +5Vdc output. The total of all outputs combined cannot exceed the stated load capacity in Watts. PME Logic Developer will automatically calculate the power consumption of modules as they are added to the system configuration. Power requirements of system modules are shown in this section, for reference when planning the system. The maximum load for each type of power supply is displayed in the following table. Catalog Number Can be Located In Nominal Input Load Capacity6 Load Sharing, Redundancy Max +3.3Vdc Max +5Vdc Max +24Vdc Isolated Max +24Vdc Relay 6 A power supply must be able to provide the total of the internal and external loads that may be placed upon it by all the hardware components in the backplane as well as by all the loads that may be connected to the Isolated +24Vdc supply on an expansion (Section 2.6.6.3) as appropriate for how each power supply is being applied. 4.1.2 24Vdc Isolated Power The IC695 Power Supplies do not have Isolated +24Vdc output terminals. The RX3i Universal Backplane provides external input terminals (TB1) for connecting an optional Isolated +24Vdc external supply. Modules that draw +24Vdc from the backplane are listed in the table Module Load Requirements, Section 4.2. Refer to Universal Backplane TB1 Input Terminals for details on how to wire to terminal TB1. 4.1.3 RX3i IC695 Power Supply Outputs The IC695 power supplies have +5.1Vdc, +24Vdc Relay, and 3.3Vdc outputs that are connected internally on the backplane. The voltage and power required by modules installed on the backplane is supplied through the backplane connectors.
