With switching times of less than 1 microsecond and a precision of \u0026lt;\u0026lt; 1 microsecond, it allows for the detection and execution of signals at a resolution far beyond standard PLC cycle times, significantly reducing jitter and increasing the deterministic performance of B2B industrial machinery.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eEL1259\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ehardware utilizes advanced FPGA-based signal processing to achieve its sub-microsecond performance. The 8 inputs are compatible with IEC 61131-2 Type 1\/3 standards, while the 8 \"push\" stage outputs provide 0.5 A each and are short-circuit proof. The multi-timestamping feature allows multiple signal edges to be captured or executed within a single EtherCAT communication cycle, effectively enabling sampling rates up to 100,000 edges per second. The module operates seamlessly within the EtherCAT E-bus architecture, providing 500 V electrical isolation between the bus and field potentials to ensure signal integrity and hardware protection in electrically noisy industrial environments.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification Details\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eEL1259\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBECKHOFF\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eI\/O Configuration\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e8 Digital Inputs + 8 Digital Outputs\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eNominal Voltage\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24 V DC (-15 percent \/ +20 percent)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eSwitching Time\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eTyp.
