New Original Keyence KV-SAD04 PLC High-Speed Analog Input Acquisition Module<\/h1>\n<\/div>\n
\n

Product Overview<\/h2>\n<\/div>\n
\n
KV-SAD04 is an original high-speed differential analog input expansion module designed exclusively for Keyence KV-3000, KV-5000, KV-7000 and KV-8000 series modular PLC systems. As a dedicated analog signal collection unit, it is equipped with 4 independent differential input channels, capable of converting continuous analog voltage and current signals from industrial field sensors into digital data readable by the PLC main CPU. It supports universal industrial standard signal ranges including \u00b110V voltage and 4\u201320mA current, featuring ultra-fast A\/D conversion speed and high conversion resolution. Connected to the PLC backplane high-speed bus, it independently completes analog signal sampling and digital conversion tasks to reduce the calculation load of the main controller. Compliant with UL, CE, RoHS and IEC industrial control standards, it delivers outstanding anti-interference performance, temperature stability and mechanical durability. It is widely adopted in precision assembly lines, packaging equipment, temperature & pressure monitoring systems, fluid control machinery, testing automation devices and all industrial scenarios requiring multi-channel analog parameter collection and closed-loop regulation\u57fa\u6069\u58eb.<\/div>\n<\/div>\n

    Primary Main Functions<\/h2>\n<\/div>\n
    \n
      \n
    1. Multi-Channel Analog Signal Acquisition: Collect real-time analog signals from temperature transmitters, pressure sensors, flow meters, displacement sensors and liquid level sensors across 4 independent channels simultaneously.<\/li>\n
    2. High-Precision A\/D Conversion: Convert continuous analog signals into high-resolution digital values for PLC to execute calculation, comparison and closed-loop control logic.<\/li>\n
    3. Differential Input Anti-Interference: Differential circuit design effectively eliminates common-mode electromagnetic noise, ensuring stable sampling data in environments with inverters and servo motors.<\/li>\n
    4. Universal Signal Range Adaptation: Freely configure voltage or current input modes to match all mainstream industrial analog output sensors without extra signal converters.<\/li>\n
    5. Built-In Sampling Average Filter: Digital filtering function suppresses signal fluctuation and jitter caused by field vibration or electrical interference for stable sampled values.<\/li>\n
    6. System Fault Self-Diagnosis: Automatically detect open-circuit sensor wiring, over-range input and module hardware failures, with LED indicators displaying fault information for rapid troubleshooting.<\/li>\n
    7. Real-Time Data Upload to CPU: Transmit converted digital data to the PLC main unit via high-speed backplane bus with ultra-low transmission delay.<\/li>\n
