Beckhoff EL3001 EtherCAT Analog Input Terminal Overview
The Beckhoff EL3001 is a 1-channel analog input terminal. It processes signals from -10V to +10V. The EL3001 digitizes voltage to 12-bit resolution. Data passes through electrical isolation to the automation device. This terminal uses single-ended inputs with common ground. LED indicators show the signal state. The EL3001 is a regular delivery product from Beckhoff.

Key Features
1 analog input – The Beckhoff EL3001 measures one ±10V signal.
12-bit resolution – Gives good accuracy for most applications.
Single-ended – Simple wiring with common ground.
500V isolation – Protects the E-bus from field voltage.
No configuration – The EL3001 works immediately after wiring.
ATEX approved – Safe for use in hazardous areas (Zone 2).
Installation Guide
Turn off power to the EtherCAT network.
Mount the EL3001 on a 35 mm DIN rail.
Push the terminal until it locks in place.
Connect the E-bus from the previous terminal.
Strip the wire to 8-9 mm (EL3001) or 9-10 mm (ES3001).
Insert the wire using a screwdriver for spring actuation.
Apply power and read the analog value in your PLC.
The Beckhoff EL3001 has no power contacts. It draws all power from the E-bus.

Frequently Asked Questions (FAQ)
1. What is the warranty period for the EL3001?
We provide a 12-month warranty from the shipment date. This covers manufacturing defects only. It does not cover damage from overvoltage, wrong wiring, or physical abuse.
2. Which shipping carriers do you use?
We ship the Beckhoff EL3001 via FedEx, UPS, or DHL. You choose the carrier at checkout. Tracking numbers are sent within 24 hours.
3. Can I use the EL3001 to measure 0-10V signals?
Yes. The EL3001 measures -10V to +10V. For 0-10V, just connect your signal and ignore the negative range. You lose no resolution because the full 12 bits cover 0-10V.
4. What is the difference between EL3001 and EL3002?
The EL3001 has 1 channel. The EL3002 has 2 channels. Both have the same ±10V range and 12-bit resolution. Choose the EL3001 for single sensor applications.
5. My reading is not stable. What can I do?
Enable the FIR/IIR filters on the Beckhoff EL3001 using your EtherCAT master. Start with a 50 Hz filter. Also check that your signal wire is shielded and grounded at one end only.
Why Choose the Beckhoff EL3001?
This EtherCAT terminal gives you one analog input in a small package. The Beckhoff EL3001 measures from -10V to +10V with 12-bit resolution. Single-ended wiring keeps installation simple. Electrical isolation of 500V protects your system. The terminal is only 12 mm wide. You can use it in Zone 2 hazardous areas (ATEX). Choose the ES3001 version for pluggable wiring. No configuration is needed – just connect and read data.
