Operating within the standard K-bus system, this terminal allows for direct calculation and calibration of bridge supply and measurement voltages to deliver accurate force, pressure, or weight measurements.\u003c\/p\u003e\n\u003cp\u003eA defining characteristic of the \u003cstrong\u003eBECKHOFF KS3356\u003c\/strong\u003e is its pluggable wiring level. Part of the KS series, it features a removable terminal block that enables swift hardware replacement during servicing or maintenance without requiring individual control wires to be disconnected and re-terminated. This architecture minimizes downtime and reduces the risk of wiring errors.\u003c\/p\u003e\n\u003cp\u003eTo ensure long-term stability and high measurement accuracy, the terminal incorporates self-calibration circuitry that compensates for environmental drift and temperature variations. It is highly suited for integration with standard PLC systems, providing highly accurate industrial weighing and force-sensing capabilities.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect input for one resistor bridge (strain gauge) with up to 16-bit resolution.\u003c\/li\u003e\n  \u003cli\u003eRemovable pluggable wiring level for simplified installation, maintenance, and field replacement.\u003c\/li\u003e\n  \u003cli\u003eSelf-calibration function that automatically compensates for drift and temperature-related measurement errors.\u003c\/li\u003e\n  \u003cli\u003eConfigurable software filters and conversion times to adapt to application-specific dynamics.\u003c\/li\u003e\n  \u003cli\u003eCompact 12 mm housing width to conserve DIN rail space within the control cabinet.\u003c\/li\u003e\n  \u003cli\u003eInternal power supply via the K-bus, with field-side distribution via the power contacts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial weighing platforms, hopper scales, and vessel weight monitoring.\u003c\/li\u003e\n  \u003cli\u003eTensile, force, and torque measurements in test stands and assembly equipment.\u003c\/li\u003e\n  \u003cli\u003eTension control systems in continuous web handling, printing, and packaging machinery.\u003c\/li\u003e\n  \u003cli\u003eMaterial testing machines requiring precise strain and force feedback.\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  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eParameter\u003c\/td\u003e\n      \u003ctd\u003eSpecification\u003c\/td\u003e\n    \u003c\/tr\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\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eKS3356\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eBus Terminal (Pluggable Wiring Level)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n      \u003ctd\u003e1 (for 1 resistor bridge)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Processing\u003c\/td\u003e\n      \u003ctd\u003eAnalog Input\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eElectrical and Signal\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eParameter\u003c\/td\u003e\n      \u003ctd\u003eSpecification\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Voltage (UD)\u003c\/td\u003e\n      \u003ctd\u003e-20 to +20 mV\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eReference Voltage (UREF)\u003c\/td\u003e\n      \u003ctd\u003e-12 to +12 V\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInternal Resistance (UD)\u003c\/td\u003e\n      \u003ctd\u003e\u0026gt;
