As part of the Beckhoff EtherCAT terminal family, it provides high-precision data acquisition for process variables such as pressure, flow, and temperature in sectors ranging from chemical processing to energy management. The terminal features a single-ended signal architecture with a 12-bit resolution, ensuring consistent and reliable feedback for high-speed control loops while minimizing measurement errors in sensitive automation tasks.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe EL3052 is engineered for seamless integration into EtherCAT fieldbus networks, requiring no manual addressing. It features two channels with an internal resistance of 85 Ohm (typical), optimized for standard industrial current-loop sensors. The signal processing architecture supports configurable conversion times (0.625 ms default) and includes advanced diagnostic features such as activatable FIR\/IIR filters and limit value monitoring. The electrical isolation of 500 V between the E-bus and signal voltage effectively decouples the control logic from field-level electrical noise, ensuring signal integrity. For users requiring easy maintenance and rapid component replacement, the \u003cstrong\u003eES3052\u003c\/strong\u003e variant is available, offering the same specifications with the added benefit of pluggable wiring.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eModel\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003eEL3052 (ES3052 with pluggable wiring)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003eBECKHOFF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eChannels\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003e2 (Single-ended)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eSignal Type\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e4–20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eResolution\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e12 bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eConversion Time\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003e0.625 ms (Configurable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003eMeasuring Error\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003e\u0026lt; ±0.3%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eIsolation\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003e500 V (E-bus\/Signal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"10\"\u003eOperating Temp\u003c\/td\u003e\n\u003ctd data-row=\"10\"\u003e-25 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"11\"\u003eDimensions\u003c\/td\u003e\n\u003ctd data-row=\"11\"\u003e12 mm x 100 mm x 68 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"12\"\u003eWeight\u003c\/td\u003e\n\u003ctd data-row=\"12\"\u003e60 g\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\u003eWhat is the functional difference between the EL3052 and ES3052?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe technical specifications are identical.
