Overview
The Beckhoff EL3054 is a 4-channel analog input EtherCAT Terminal for 4–20 mA current signals. Each channel is digitized with 12-bit resolution and transmitted galvanically isolated to the controller. The 24 V power contact is routed through the terminal to enable direct connection of 2‑wire sensors without an external supply. LEDs indicate run/error conditions and wire break/overload.
Key Features
- 4 single-ended current inputs, 4–20 mA
- 12-bit resolution; default conversion time 0.625 ms (configurable, multiplex)
- Independent of power-contact supply; 24 V power contact passed through for 2‑wire sensors
- Integrated diagnostics: overload and wire-break indication
- Electrical isolation between E‑bus and signal voltage (500 V)
- Compact 12 mm IP20 terminal for space-saving control cabinets
Applications
- Acquisition of 4–20 mA process signals from transmitters and sensors
- Control panels needing compact, isolated multi-channel analog inputs
