Engineered for demanding industrial environments—including power generation plants, chemical processing facilities, and automated manufacturing lines—this module provides 4 differential inputs capable of handling both current and voltage signals. By delivering reliable, high-resolution signal acquisition, the X20AI4622 significantly reduces sensor-to-controller latency and mitigates the risk of unscheduled downtime caused by signal inaccuracies. Its compact design and modular architecture ensure seamless integration into existing control cabinets, providing the robust data fidelity required for complex closed-loop control applications.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe module features a high-precision 13-bit digital converter (including sign) based on the Successive Approximation Register (SAR) conversion procedure. It is built for versatility, allowing the user to switch between voltage (plus\/minus 10 V) and current (0 to 20 mA or 4 to 20 mA) modes simply by selecting the appropriate terminal connection points. The module is engineered with a 3rd-order low-pass input filter with a cutoff frequency of 1 kHz to eliminate high-frequency noise from industrial machinery. Electrical isolation is provided between the I\/O channels and the backplane bus, protecting the CPU and downstream processing components from potential transients. Status monitoring is comprehensive, with integrated LEDs for channel-specific I\/O functions and module-wide error diagnostics accessible via software.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eModel\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003eX20AI4622\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003eB\u0026amp;R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eAnalog Inputs\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003e4 Differential\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eResolution\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e13-bit (including sign)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eConversion Time\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e400 microseconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eInput Impedance (Voltage)\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003e20 MOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003eInput Protection\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003eMax plus\/minus 30 V (Voltage) \/ Max plus\/minus 50 mA (Current)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eBus Power Consumption\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003e0.01 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"10\"\u003eInternal I\/O Power\u003c\/td\u003e\n\u003ctd data-row=\"10\"\u003e1.1 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"11\"\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd data-row=\"11\"\u003e-25 to 60 deg C (Horizontal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"12\"\u003eProtection Rating\u003c\/td\u003e\n\u003ctd data-row=\"12\"\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"13\"\u003eWeight\u003c\/td\u003e\n\u003ctd data-row=\"13\"\u003e1.0 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the X20AI4622 compatible with all X20 series backplanes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, it is designed for the standard X20 system architecture, but you must order the X20BM11 bus module and X20TB12 terminal block separately as they are not included with the module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I switch between voltage and current input modes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe selection is hardware-dependent.
