Designed for high-volume serial machine manufacturing, this component is ideal for assembly lines, packaging automation, and automated handling systems where space efficiency and cost-optimized wiring are critical. By enabling direct connection to application-specific PCBs, the EJ1809 eliminates traditional terminal block wiring, significantly accelerating cabinet assembly times and reducing overall machine footprint while maintaining reliable 24 VDC signal acquisition.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThis module provides sixteen independent digital input channels conforming to EN 61131-2 Type 1\/3 standards. Each channel is equipped with a 3.0 ms input filter to effectively suppress high-frequency noise and transient electrical interference common in industrial environments. The architecture features 500 V electrical isolation between the field potential and the E-bus, ensuring the protection of the EtherCAT communication backbone. With a low E-bus power consumption of 80 mA, the EJ1809 is optimized for integration into compact, multi-module systems, delivering consistent performance without overloading the local power distribution infrastructure.\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\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eEJ1809\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBrand\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\u003eNumber of Channels\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e16\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eInput Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eDigital, Type 1\/3\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eNominal Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24 VDC (-15% to +20%)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eInput Filter\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e3.0 ms\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eE-bus Consumption\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eTyp 80 mA\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eElectrical Isolation\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e500 V\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOperating Temp\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-25 to 60 deg C\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eApprox 30 g\u003c\/span\u003e\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\u003eHow is the EJ1809 mounted within the system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe EJ1809 is a plug-in module designed to be mated directly to a custom-designed application PCB via its integrated pin headers, rather than being mounted on a standard DIN rail.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this module compatible with Type 3 sensors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the EJ1809 inputs meet EN 61131-2 Type 1\/3 requirements, ensuring full compatibility with a wide range of standard industrial 24 VDC proximity switches and sensors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the benefits of the 3 ms filter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 3 ms input filter provides a robust barrier against contact bounce and electrical noise, preventing false signal triggers in standard automation applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan multiple EJ1809 modules be used in a single system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the EtherCAT protocol allows for the concatenation of multiple EJ-series modules to scale the total I\/O count according to the requirements of the machine architecture.\u003c\/p\u003e\n\u003ch3\u003eInstallation and Operational Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePCB Design Integration:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eWhen designing the carrier PCB, ensure the signal traces are routed with adequate spacing from high-power circuits to minimize crosstalk.
