This digital input module is engineered to acquire binary control signals from the physical process level and transmit them reliably to the controller over high-speed EtherCAT. Housed in a zinc die-cast casing, it provides reliable protection against moisture, dust, and mechanical stress in harsh industrial automation environments.\u003c\/p\u003e\n\u003cp\u003eThis module features 16 digital inputs configured with standard M8 connections suitable for three-wire sensors. The inputs conform to the EN 61131-2 Type 1\/3 specification and integrate a fast 10-microsecond input filter to ensure swift and accurate signal transition capture. The compact, decentralized architecture reduces cabling footprint, simplifies field wiring, and optimizes communication performance direct to the machine level.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e16 digital inputs for dense binary signal acquisition\u003c\/li\u003e\n  \u003cli\u003eStandard M8, 3-pin, A-coded sensor connection technology\u003c\/li\u003e\n  \u003cli\u003eFast 10-microsecond input filter configuration for high-speed responsiveness\u003c\/li\u003e\n  \u003cli\u003eZinc die-cast housing offering IP65, IP66, and IP67 ingress protection\u003c\/li\u003e\n  \u003cli\u003eIntegrated sensor supply driven from control voltage, short-circuit proof up to 0.5 A in total\u003c\/li\u003e\n  \u003cli\u003eDirect EtherCAT communication via dual shielded M8 screw-type sockets\u003c\/li\u003e\n  \u003cli\u003e500 V electrical isolation to protect upper-level control electronics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDecentralized machine control systems without protective enclosures\u003c\/li\u003e\n  \u003cli\u003eMaterial handling, logistics, and conveyor systems with dense sensor clusters\u003c\/li\u003e\n  \u003cli\u003eRobotics, packaging machinery, and assembly systems requiring localized I\/O nodes\u003c\/li\u003e\n  \u003cli\u003eWet or dusty industrial environments requiring resilient IP67 field modules\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eGeneral\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eER1819-0021\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHousing Material\u003c\/td\u003e\n      \u003ctd\u003eZinc die-cast\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtection Rating\u003c\/td\u003e\n      \u003ctd\u003eIP65\/IP66\/IP67 (conforms to EN 60529)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n      \u003ctd\u003e60 mm x 126 mm x 26.5 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003eapprox. 450 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eSignal and I\/O\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n      \u003ctd\u003e16\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Connection Type\u003c\/td\u003e\n      \u003ctd\u003eM8 x 1, 3-pin, A-coded\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Specification\u003c\/td\u003e\n      \u003ctd\u003eEN 61131-2, type 1\/3\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Input Voltage\u003c\/td\u003e\n      \u003ctd\u003e24 V DC (-15% \/ +20%)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\"0\" Signal Voltage\u003c\/td\u003e\n      \u003ctd\u003e-3 to +5 V (EN 61131-2, type 3)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e\"1\" Signal Voltage\u003c\/td\u003e\n      \u003ctd\u003e11 to 30 V (EN 61131-2, type 3)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Current\u003c\/td\u003e\n      \u003ctd\u003etyp. 3 mA (EN 61131-2, type 3)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Filter\u003c\/td\u003e\n      \u003ctd\u003e10 microseconds\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSensor Supply\u003c\/td\u003e\n      \u003ctd\u003eFrom control voltage (Us), max. 0.5 A, short-circuit proof in total\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eElectrical and Communication\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtocol\u003c\/td\u003e\n      \u003ctd\u003eEtherCAT\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBus Interface\u003c\/td\u003e\n      \u003ctd\u003e2 x M8 socket, shielded, screw type\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Supply Connection\u003c\/td\u003e\n      \u003ctd\u003eFeed: 1 x M8 male, 4-pin;
