This unit automatically configures and maps the digital, analog, and specialty process signals from up to 64 connected I\/O terminals directly into the control system's memory. By using fiber-optic transmission media, the module ensures complete electrical isolation, high noise immunity, and rapid data exchange rates of 2.5 MBaud. This configuration makes it highly suitable for complex, geographically distributed control architectures where electrical noise and ground loops are common concerns.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrates a specialized Lightbus fiber-optic interface for high-speed, noise-free industrial communication.\u003c\/li\u003e\n  \u003cli\u003eSupports the direct connection of up to 64 Beckhoff Bus Terminals to a single node.\u003c\/li\u003e\n  \u003cli\u003eProvides an internal K-bus output current of up to 1.75 A to power connected I\/O terminal logic.\u003c\/li\u003e\n  \u003cli\u003eEquipped with an integrated configuration interface compatible with the KS2000 software tool.\u003c\/li\u003e\n  \u003cli\u003eFeatures integrated, isolated 24 V DC power contacts for reliable peripheral power distribution.\u003c\/li\u003e\n  \u003cli\u003eRobust IP20-rated housing with a compact DIN-rail mounting profile.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDistributed control networks in high-voltage and power-generation facilities.\u003c\/li\u003e\n  \u003cli\u003eAutomotive assembly lines prone to high electromagnetic welding interference.\u003c\/li\u003e\n  \u003cli\u003eWater and wastewater treatment facility telemetry.\u003c\/li\u003e\n  \u003cli\u003eHeavy machinery and packaging systems requiring robust, isolated I\/O nodes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003cth\u003eParameter\u003c\/th\u003e\n    \u003cth\u003eValue\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003ePart Number\/Model\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eBK2000\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eLightbus Bus Coupler\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eCommunication Protocol\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003eLightbus (fiber-optic)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eBaud Rate\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e2.5 MBaud\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eSupply Voltage\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e24 V DC (+\/- 10%)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eInput Current\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e105 mA typical, 900 mA maximum\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eK-bus Output Current\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e1.75 A maximum\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eSupply Isolation\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd\u003e500 Veff (K-bus \/ supply voltage)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cstrong\u003eMax.
