The EL3052 (EL3052) is a versatile 2-channel analog input terminal designed to interface with 4–20 mA current loops in industrial automation environments. 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.
The 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 ES3052 variant is available, offering the same specifications with the added benefit of pluggable wiring.
| Feature | Specification |
| Model | EL3052 (ES3052 with pluggable wiring) |
| Brand | BECKHOFF |
| Channels | 2 (Single-ended) |
| Signal Type | 4–20 mA |
| Resolution | 12 bit |
| Conversion Time | 0.625 ms (Configurable) |
| Measuring Error | < ±0.3% |
| Isolation | 500 V (E-bus/Signal) |
| Operating Temp | -25 to 60 deg C |

What is the functional difference between the EL3052 and ES3052?
The technical specifications are identical. The ES3052 model features a pluggable wiring interface, allowing you to remove the terminal block without disconnecting individual wires, which facilitates faster maintenance in modular systems.
Can this terminal handle voltage signals in addition to current?
No, the EL3052 is specifically hardware-configured for 4–20 mA current loop signals. Using it with voltage sources may damage the input stage.
How do the FIR/IIR filters improve my measurements?
These digital filters help suppress high-frequency noise and interference present in the current loop, providing a more stable and readable value in the process image without requiring external analog filtering.
What does "single-ended" technology imply for my wiring?
In a single-ended configuration, the measurement signal is referenced to a common ground potential within the terminal. Ensure all your sensor ground references are consistent to prevent potential differences that could affect measurement accuracy.
