Frequently Asked Questions (FAQ)

• What is the maximum input voltage for the EL3164?

  The maximum dielectric strength is 30 V. Do not exceed this.

• Can I use this terminal with 4‑20 mA sensors?

  No, it only accepts 0‑10 V signals. Use EL3124 for current inputs.

• How do I activate the built‑in filter?

  Enable FIR/IIR filters via the EtherCAT master (TwinCAT) configuration.

• Is the EL3164 suitable for Ex‑rated environments?

  Yes, it has Ex approval for Zone 2 hazardous areas.

• What does the “compact process image” do?

  It packs the data into fewer bytes, saving memory.

• What is the temperature range for operation?

  0…+55 °C. Storage: -25…+85 °C.

Experience‑Based Buying Guide

• Choose the EL3164 for standard 0‑10 V analog sensors.
• If you need 4‑20 mA, consider the EL3124 instead.
• For higher accuracy, look at the EL3162 (2‑channel, 16‑bit).
• For differential inputs, select the EL3168.
• Always verify the common ground matches your sensor wiring.
• Use shielded cables for long distances to reduce noise.

Comparison with Similar Models
