Beckhoff EL3048 EtherCAT Terminal

The EL3048 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitized to a resolution of 12 bits and is transmitted (electrically isolated) to the higher-level automation device. The EL3048 EtherCAT Terminal combines eight channels in one housing. The power contacts are connected through. The 0 V power contact is used as reference ground connection for the inputs. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.

    Core Features & Advantages

    • High Channel Density & Space-Saving Design: The module's standout feature is its combination of eight analog input channels in a single, compact 12 mm housing. This high-density design allows for significant space savings in the control cabinet, making it ideal for applications with a large number of analog signals.

    • High Precision & Measurement Accuracy: With a 12-bit resolution and a high-precision internal resistance of typ. 85 Ω, the EL3048 ensures accurate current measurement. The measurement error of less than ±0.3% relative to the full scale value guarantees reliable signal acquisition for precise process control.

    • Flexible & User-Friendly Configuration: Configuration is straightforward, as the terminal requires no address or configuration settings and is automatically recognized by the EtherCAT system. It also offers standard and compact process image modes, activatable FIR/IIR filters for signal smoothing, and limit value monitoring features to enhance diagnostic capabilities and reduce the CPU load.

    • Robust Design for Harsh Environments: The EL3048 is designed for industrial reliability, featuring a wide operating temperature range from -25°C to +60°C and a storage temperature range of -40°C to +85°C. It is compliant with EN 60068-2-6/EN 60068-2-27 for vibration/shock resistance and EN 61000-6-2/EN 61000-6-4 for EMC immunity/emission. The terminal is also ATEX and IECEx approved for use in potentially explosive atmospheres (II 3 G Ex ec IIC T4 Gc).

    Typical Applications

    The EL3048 is widely used in industrial and building automation applications requiring the acquisition of 0…20 mA analog signals, such as:

     

    • Process Automation: Connecting pressure, temperature, and flow sensors for monitoring and control in chemical, pharmaceutical, and food processing plants.

    • Machine Building: Integrating with various transmitters and sensors for manufacturing and packaging machinery.

    • Test & Measurement: Data acquisition from multiple sensors in testing and quality assurance processes

    The EL2535-0002 output terminals are specially designed for the precise control of single and double-coil proportional valves and proportional solenoid valves. They regulate the output current through pulse width modulation (PWM) of the supply voltage and are electrically isolated from the E-bus. The current values (0 to maximum output current) are specified by the automation device through a 16-bit value. The output stages are protected against overload and short circuit. Each EtherCAT pulse width current terminal contains two channels whose signal state is indicated by LEDs. The light emitting diodes simplify local diagnosis by displaying typical load and wiring faults.
