EL3058 | Beckhoff EtherCAT Terminal, 8-Channel Analog Input, 4–20 mA, 12-Bit, Single-Ended

BECKHOFF · HMIs & Displays

Description  The Beckhoff EL3058 is an 8-channel analog input EtherCAT Terminal designed to process current signals in the 4…20 mA range. Each channel converts the input signal with 12-bit resolution (16-bit representation) and transmits the data electrically isolated to the higher-level controller. Ideal for compact and efficient analog signal acquisition, the terminal includes diagnostic LEDs for signal status, overload conditions, and broken wire detection. The EL3058 provides reliable current measurement for industrial automation systems requiring multi-channel, high-density input solutions.     Technical Specifications Condition New/Never Used Surplus Manufacturer Beckhoff Part Number EL3058 Product Type Analog Input Terminal Channels 8 Signal Range 4…20 mA Internal Resistance ~85 Ω Resolution 12-bit (16-bit presentation) Conversion Time ~1.25 ms (50 Hz filter) Input Filter Limit Frequency 1 kHz E-Bus Current Consumption ~130 mA Electrical Isolation 500 V (E-bus/field voltage) Dielectric Strength Max. 30 V EMC Compliance EN 61000-6-2 / EN 61000-6-4 Humidity 95% non-condensing Mounting 35 mm DIN rail (EN 60715) Dimensions (H × W × D) ~100 × 15 × 70 mm Protection Rating IP20 Subcategory PLC Programming Terminal Category PLCs/Machine Control     Information About EL3058 The EL3058 EtherCAT Terminal is engineered to handle eight single-ended current input channels within a single compact housing, making it an efficient solution for high-channel-count analog current measurement. Each input supports the industry-standard 4…20 mA range, widely used for process instrumentation such as pressure, flow, and level transmitters. With a typical conversion time of 1.25 ms at the default 50 Hz filter setting and a 1 kHz input filter limit frequency, the EL3058 delivers stable, real-time data suitable for both slow and moderately dynamic process variables. Diagnostics include LED indicators for each channel and error LEDs to signal wiring breaks or overloads, enhancing system reliability and simplifying troubleshooting. Key Features: 8 single-ended analog current input channels (4…20 mA) 12-bit resolution (16-bit data representation) Fast conversion time: ~1.25 ms (default 50 Hz filter) Integrated diagnostics: signal LEDs, overload, and broken-wire detection 1 kHz input filter limit frequency for clean and stable measurement Electrical isolation: 500 V between field voltage and E-bus Compact, high-density design saves panel space DIN rail mount compatible with EN 60715 EMC-compliant for industrial environments Ideal for process instrumentation and distributed analog acquisition Electrical isolation of 500 V separates the E-bus from field voltage, ensuring operator and equipment protection. Designed for 35 mm DIN rail mounting (EN 60715), the EL3058 seamlessly integrates into Beckhoff’s modular terminal ecosystem and is suitable for demanding industrial environments thanks to its EMC compliance and ability to operate in high humidity (up to 95% non-condensing).
