Featuring 16 digital inputs in a compact form factor, this module is specifically engineered for the EJ series signal distribution board system, which replaces traditional point-to-point wiring with a standardized PCB-based connection level. In high-speed packaging, electronics assembly, and complex robotic cells, the \u003cstrong\u003eEJ1819\u003c\/strong\u003e significantly reduces the risk of wiring errors and minimizes the cabinet footprint. Its ultra-fast 10 microsecond input filter ensures precise signal acquisition for time-critical processes, making it a cornerstone for high-performance machine control and reduced system integration time.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eEJ1819\u003c\/strong\u003e operates as a standard 24 VDC digital input interface, conforming to EN 61131-2, type 1\/3 specifications. Its architecture is optimized for high-density I\/O density, utilizing a plug-in design that connects directly to an application-specific Signal Distribution Board via a standardized connector. The module provides 16 channels of data, each drawing a typical input current of 3 mA. Signal integrity is maintained through 500 V electrical isolation between the E-bus and the field potential. Despite the high channel count, the module maintains a low power profile with a typical E-bus current consumption of 80 mA. The absence of Distributed Clocks (DC) is compensated by the module's high-speed internal processing and extremely low filter latency, suitable for rapid-fire sensor feedback.\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\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eEJ1819\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\u003eModule Type\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eEtherCAT Plug-in Module (Digital Input)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e\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\u003e\u003cstrong\u003eNominal Voltage\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24 VDC (-15 percent \/ +20 percent)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eSignal Voltage \"0\"\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e-3 to +5 V (EN 61131-2, type 1\/3)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eSignal Voltage \"1\"\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e11 to 30 V (EN 61131-2, type 3)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eInput Filter\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003etyp. 10 microseconds\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eE-bus Current Consumption\u003c\/strong\u003e\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\u003e\u003cstrong\u003eElectrical Isolation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e500 V (E-bus \/ field potential)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\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\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eapprox. 30 g\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eShipping Weight\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2.0 kg\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003eProtection Rating\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP20\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eTechnical FAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the EJ1819 differ from the EL1819 terminal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe EJ1819 provides the same 16-channel digital input functionality as the EL1819 but uses a plug-in housing designed for Signal Distribution Boards. While the EL series uses spring-loaded terminals for individual wires, the EJ series uses a multi-pin connector on the rear for mass-interconnect PCB mounting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the benefits of the 10 microsecond input filter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 10 microsecond filter is significantly faster than standard industrial filters (often 3 ms). This allows the controller to detect extremely short pulses or high-frequency transitions from sensors, which is essential for high-speed counting or precision positioning tasks in automated assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the EJ1819 be used in high-vibration environments?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the EJ1819 conforms to EN 60068-2-6 and EN 60068-2-27 standards. When properly seated on a Signal Distribution Board and secured, the plug-in design offers superior mechanical stability compared to traditional DIN rail terminals in high-vibration machinery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it possible to mix EJ modules with different voltage levels on the same board?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis depends entirely on the design of your specific Signal Distribution Board. The EJ1819 requires a 24 VDC field potential.
