Designed for versatile industrial applications, this \"combi\" terminal supports 24 V DC signals and is optimized for efficient signal processing in compact control cabinets. By providing a high channel density, the EL1859 minimizes the footprint of I\/O assemblies while maintaining the deterministic, high-speed communication performance of the EtherCAT network. It is ideal for machine control systems requiring a balance of monitoring and actuation capabilities, including sensor feedback collection and small actuator control for conveyors, packaging, and assembly lines.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe EL1859 features a 1-wire connection technology, significantly reducing the amount of field wiring required. The input stages comply with EN 61131-2 (type 1\/3), ensuring robust compatibility with a wide range of standard sensors. The output channels are capable of driving ohmic, inductive, and lamp loads with a maximum current of 0.5 A per channel, complemented by integrated reverse voltage protection to safeguard the hardware against wiring errors or transient back-EMF from inductive loads. The module utilizes a high-density (HD) polycarbonate housing, supporting side-by-side mounting via a double slot and key connection, which ensures mechanical stability on standard 35 mm DIN rails.\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\u003eEL1859\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\u003eChannels\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\u003eNominal Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24 V DC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOutput Current\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.5 A per channel\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\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e65 g\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eDimensions\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e12 mm x 100 mm x 68 mm\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\u003e0 deg C to 55 deg C\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eProtection Class\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\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the HD (High Density) housing differ from standard terminals?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe HD housing allows for a higher number of I\/O points within the same 12 mm width by optimizing the terminal layout and connection density, perfect for applications where control cabinet space is limited.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it necessary to set an address for the EL1859 during installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Like all standard Beckhoff EtherCAT terminals, the EL1859 is auto-configured by the EtherCAT master; there are no manual address or configuration switches required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I drive inductive loads directly with the output channels?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the outputs are designed to handle inductive loads.
