Operating within the 0 to 10 V range with 12-bit resolution, this terminal facilitates reliable communication between the EtherCAT network and peripheral actuators such as proportional valves, frequency converters, or heating control elements. With support for Distributed Clocks (DC) and a sub-microsecond precision, the EL4002 ensures deterministic control performance, which is vital for high-speed synchronization in multi-axis motion and complex process control systems, ultimately reducing signal latency and enhancing overall system stability.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe EL4002 utilizes a 2-wire, single-ended connection architecture, optimized for stable 0 to 10 V voltage output with a load capability exceeding 5 kOhm. The module is fully integrated into the EtherCAT E-bus, providing electrical isolation up to 500 V between the field potential and the internal communication bus. A standout feature of the EL4002 is its user-configurable watchdog and synchronization capabilities; these allow engineers to define safe-state output values during network interruptions, including ramp-based transitions to prevent sudden mechanical movements, thereby safeguarding equipment and personnel.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eEL4002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBECKHOFF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Voltage\u003c\/td\u003e\n\u003ctd\u003e0 to 10 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e12 bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConversion Time\u003c\/td\u003e\n\u003ctd\u003e150 µs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Error\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.1 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 5 kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-25 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the Distributed Clock (DC) feature benefit the application?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Distributed Clock feature allows the terminal to synchronize its output conversion with the EtherCAT master's system time. With a precision of significantly less than 1 µs, it ensures that analog signals change exactly when required, eliminating timing jitter in the process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the purpose of the watchdog feature in this terminal?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe watchdog is a safety function that monitors the EtherCAT communication link. If communication is lost, the terminal automatically switches the outputs to a pre-defined safe state, which can be configured as a fixed value or a ramped sequence to avoid dangerous machine behavior.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use the EL4002 for inductive loads?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe terminal is designed for voltage output signals (0...10 V) with a load requirement \u0026gt; 5 kΩ. It is not intended to drive high-current inductive actuators directly. If driving such devices, ensure the input impedance of the secondary device meets the terminal's load requirements or use an intermediate signal converter.\u003c\/p\u003e\n\u003ch3\u003eInstallation and Operational Recommendations\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Integrity:\u003c\/strong\u003e Given the 12-bit resolution, maintain high signal integrity by using shielded, twisted-pair cabling for all analog output connections. Terminate the shield at the cabinet's grounding busbar to minimize noise pickup from surrounding power cables.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring Technique:\u003c\/strong\u003e Utilize the spring-actuation terminals with an appropriate screwdriver. When using flexible conductors, ferrules are highly recommended to prevent strand splaying, which can cause intermittent contact resistance and signal drift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide-by-Side Mounting:\u003c\/strong\u003e The EL4002 supports side-by-side mounting using a double slot and key connection. When placing multiple analog modules together, be mindful of heat dissipation; although the current consumption is low (typ. 140 mA E-bus), maintaining a consistent operating environment ensures the long-term accuracy of the output stages.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BECKHOFF","offers":[{"title":"Default Title","offer_id":53106603622763,"sku":"EL4002","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/el4002-ahyppf04ep2.png?v=1776244508","url":"https:\/\/www.plcprotech.com\/fr\/products\/beckhoff-el4002-el-series-analog-output-terminal","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
