Engineered for applications requiring extreme speed and microsecond-level accuracy, this module is ideal for tasks such as registration mark detection, pulse duration measurement, and high-speed motion sequence generation. By decoupling signal processing from the standard X2X Link cycle time through integrated timestamp and oversampling technology, it provides high-fidelity control in high-speed manufacturing, assembly, and packaging environments.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe X20DS4389 features a highly flexible I\/O architecture:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 Dedicated Digital Inputs:\u003c\/strong\u003e Designed for 24 VDC operation with high-speed response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 Configurable Channels:\u003c\/strong\u003e Can be independently set as either digital inputs or outputs to suit specific application needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetTime Support:\u003c\/strong\u003e Integrated timestamping with 125 ns resolution, allowing for precise event tracking regardless of bus communication latency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversampling Capability:\u003c\/strong\u003e Enables the acquisition and generation of signal patterns with durations shorter than the X2X Link cycle time (up to 25 µs scan rates).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Detection:\u003c\/strong\u003e Each of the 4 units supports pulse duration\/differential time measurement and includes history buffers for event logging.\u003c\/li\u003e\n\u003c\/ul\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\"\u003eX20DS4389\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\"\u003eDigital Inputs\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eConfigurable I\/O\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eOutput Current\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003e0.1 A per channel (0.4 A total)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003eTimestamp Resolution\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003e125 ns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eSampling Rate (Oversampling)\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003e25 µs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"10\"\u003eWeight\u003c\/td\u003e\n\u003ctd data-row=\"10\"\u003e0.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"11\"\u003eProtection Rating\u003c\/td\u003e\n\u003ctd data-row=\"11\"\u003eIP20\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\u003eWhat are the primary industrial applications for this module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe X20DS4389 is used in automation tasks that require high-speed precision, such as high-speed sorting, registration mark sensing on packaging lines, and precise timing for drum sequencers or industrial actuators.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the timestamp function improve performance?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe integrated timestamp function records the exact time an input edge occurs with 125 ns resolution.
