Beckhoff EL3164 4-Channel Analog Input Terminal
The Beckhoff EL3164 is a 4-channel analog input terminal for 0 to 10 V single-ended signals. It digitises voltage with 16-bit resolution and sends data electrically isolated to the higher-level automation device. The EL3164 uses 2-wire conductors for four single-ended inputs with a common internal ground. Power contacts pass through, and LEDs show signal state. This terminal suits precise measurement tasks in EtherCAT systems.

FAQ
Q: Can I use the EL3164 with a 0-20 mA signal?
A: No. The EL3164 reads 0-10 V only. Use a current input terminal for 0-20 mA.
Q: How do I know if the EL3164 fits my old Beckhoff rack?
A: Check that your coupler supports EL terminals and EtherCAT. The EL3164 uses the standard E-bus.
Q: What filter setting should I choose for slow sensors?
A: Use the IIR filter for slow signals. It reduces noise but adds a small delay.
Q: Why does my reading drift at long cable runs?
A: Single-ended inputs are sensitive to ground noise. Use shielded cable and short runs.
Q: Should I buy new or refurbished for a spare part?
A: For critical lines, buy tested refurbished with warranty. For new builds, choose new stock.
