It is designed to enable wireless communication with EnOcean-compatible sensors and actuators in building automation and industrial control environments. The terminal itself does not contain high-frequency transmitter or receiver hardware; instead, it acts as a central controller and interface module that connects to external transceivers.\u003c\/p\u003e\n\u003cp\u003eTo achieve wide radio coverage across a building, the \u003cstrong\u003eBECKHOFF KL6581\u003c\/strong\u003e supports the connection of up to eight external BECKHOFF KL6583 EnOcean transmitter and receiver modules. This distributed architecture allows physical transceivers to be positioned at optimal locations away from the control cabinet, overcoming distance limitations and avoiding building structure interference.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEnOcean master interface terminal for K-bus systems\u003c\/li\u003e\n  \u003cli\u003eSupports connection of up to eight KL6583 EnOcean transceiver modules\u003c\/li\u003e\n  \u003cli\u003eInternal data transfer rate of 125 kbaud between the master terminal and transceivers\u003c\/li\u003e\n  \u003cli\u003eEnables extended physical network layout with up to 500 meters of total connection cable length\u003c\/li\u003e\n  \u003cli\u003ePower supply provided directly via the K-bus connection\u003c\/li\u003e\n  \u003cli\u003eCompact housing design suitable for standard DIN rail mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBuilding automation systems requiring wireless EnOcean sensor integration\u003c\/li\u003e\n  \u003cli\u003eIndustrial remote monitoring where physical wiring is impractical\u003c\/li\u003e\n  \u003cli\u003eRetrofitting existing machinery or facilities with wireless controls\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eGeneral\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExact Model\u003c\/td\u003e\n      \u003ctd\u003eKL6581\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eBus Terminal (EnOcean Master)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Temperature\u003c\/td\u003e\n      \u003ctd\u003e0 degC to +55 degC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStorage Temperature\u003c\/td\u003e\n      \u003ctd\u003e-25 degC to +85 degC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRelative Humidity\u003c\/td\u003e\n      \u003ctd\u003e95%, no condensation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtection Rating\u003c\/td\u003e\n      \u003ctd\u003eIP20\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003eapprox. 85 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eApprovals\u003c\/td\u003e\n      \u003ctd\u003eCE, UL\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eElectrical and Interface\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Voltage\u003c\/td\u003e\n      \u003ctd\u003e24 V DC (-15% \/ +20%)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCurrent Consumption (K-bus)\u003c\/td\u003e\n      \u003ctd\u003etyp. 60 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCurrent Consumption (Power Contacts)\u003c\/td\u003e\n      \u003ctd\u003etyp. 20 mA + load\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eData Transfer Rate\u003c\/td\u003e\n      \u003ctd\u003e125 kbaud\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax.
