This module provides the essential feed for the X2X Link communication lines and the internal I\/O supply, ensuring seamless data flow and power distribution across the terminal block.

By offering electrical isolation between the feed and the X2X Link supply, it protects the system from potential electrical interference, while its support for redundant supply configurations ensures maximum uptime in mission-critical environments.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe hardware architecture of the X20BR9300 is designed for specific placement and high reliability. It must be operated exclusively on the slot to the far left of an I\/O station to correctly initialize the bus segment. The module integrates a dual-purpose feed mechanism that powers both the internal communication logic and the attached I\/O modules. A key feature of this unit is the ability to operate multiple supply modules simultaneously, allowing for redundancy in the X2X Link power supply; if one supply fails, the system continues to operate without interruption. The electrical isolation between the input power and the internal bus logic prevents ground loops and voltage spikes from damaging the sensitive communication architecture. For a complete installation, the module is supplied with both the left and right end plates to ensure proper mechanical termination of the X20 rack.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eX20BR9300\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBrand\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eB\u0026amp;R (Bernecker + Rainer)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModule Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eX2X Link Bus Receiver\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eFunction\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFeed for X2X Link and Internal I\/O\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eIsolation\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eElectrical isolation between feed and bus\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eRedundancy\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSupported (via simultaneous supply modules)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eSlot Requirement\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eFar left slot only\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eIncluded Accessories\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eLeft and right end plates\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperating Temp\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0 to 55 deg C\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eProtection Rating\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP20\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eShipping Weight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.0 kg\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eTechnical FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhy must the X20BR9300 always be placed in the far left slot?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe far left slot is the hardware-defined entry point for the X2X Link bus.
