This module serves as a critical communication bridge, facilitating reliable data exchange between distributed I\/O systems and the main controller via two electrically isolated CAN interfaces. Its design prioritizes operational continuity in high-noise environments, such as large-scale material handling systems, automated logistics, and multi-axis motion control applications, where robust network communication is vital to preventing system-wide downtime.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe 7EX470.50-1 is built for high-performance network integration, featuring dual CAN interfaces that are electrically isolated to prevent ground-loop interference. The module allows for precise configuration of network parameters, including node identification and baud rate, via an integrated number switch located on the front panel.\u003c\/p\u003e\n\u003cp\u003eIn terms of power management, the module operates on a standard 24 VDC supply (with an operational range of 18 VDC to 30 VDC). Beyond its own power consumption (max. 20 W), it acts as a power distribution node, providing 14.5 W of output power to support connected I\/O and screw-in modules. This integrated power delivery simplifies cabinet wiring and ensures that peripheral modules remain powered consistently within the 2003 rack system.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eModel\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003e7EX470.50-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003eB\u0026amp;R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eSeries\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003eB\u0026amp;R 2003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eModule Type\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003eCAN Bus Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eCAN Interfaces\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e2 (Electrically isolated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eInput Voltage\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003e18 to 30 VDC (Nominal 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003ePower Consumption\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003eMax. 20 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eI\/O Power Output\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003e14.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"10\"\u003eInterface\u003c\/td\u003e\n\u003ctd data-row=\"10\"\u003e9-pin D-type socket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"11\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd data-row=\"11\"\u003eIntegrated Number Switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"12\"\u003eWeight\u003c\/td\u003e\n\u003ctd data-row=\"12\"\u003e1.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the purpose of the number switch on the module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe number switch is a physical interface used to manually set the CAN node address and the network baud rate, ensuring the controller is correctly recognized by the master system during commissioning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does electrical isolation benefit the CAN bus network?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eElectrical isolation protects the module's communication transceivers from voltage spikes and ground potential differences between different nodes on the network, which significantly increases network reliability and prevents port damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I daisy-chain power through this module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 7EX470.50-1 provides 14.5 W of output power to adjacent I\/O modules within the same rack.
