It generates industrial control signals in the 0 to 10 V range with a 12-bit resolution, providing precise analog command signals for actuators, drives, and control valves. As part of the modular Bus Terminal series, the KL4404 connects directly to a Bus Coupler or BK-series node via the K-bus, integrating seamlessly into decentralized automation architectures.\u003c\/p\u003e\n\u003cp\u003eThis single-ended analog output module processes four independent output channels through standard wiring connections. The unit features short-circuit-proof outputs and reliable electrical isolation between the field-side signal voltage and the K-bus logic, ensuring stable operation within industrial control panels. Configuration is handled entirely through the higher-level controller and fieldbus system without requiring manual address or parameter settings on the device itself.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour analog output channels supporting the 0 to 10 V signal range\u003c\/li\u003e\n  \u003cli\u003e12-bit internal resolution for accurate signal generation\u003c\/li\u003e\n  \u003cli\u003eSingle-ended output technology with short-circuit protection\u003c\/li\u003e\n  \u003cli\u003eDirect connection to the K-bus for internal data exchange and power supply\u003c\/li\u003e\n  \u003cli\u003eConfigurable process image supporting 4 x 16-bit output data with optional 4 x 8-bit control and status bytes\u003c\/li\u003e\n  \u003cli\u003ePluggable wiring interface compatible with standard KSxxxx Bus Terminal accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eControlling proportional valves and actuators in factory automation\u003c\/li\u003e\n  \u003cli\u003eProviding setpoint values for variable frequency drives and motor controllers\u003c\/li\u003e\n  \u003cli\u003eDriving analog panel meters and indicator displays\u003c\/li\u003e\n  \u003cli\u003eInterfacing with data acquisition and process control systems requiring analog output signals\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\u003eKL4404\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eBus Terminal\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTechnology\u003c\/td\u003e\n      \u003ctd\u003eSingle-ended\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n      \u003ctd\u003e4\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eElectrical\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\u003eSignal Voltage\u003c\/td\u003e\n      \u003ctd\u003e0 to 10 V\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLoad Impedance\u003c\/td\u003e\n      \u003ctd\u003e\u0026gt;
