EL2889 Beckhoff 16-Channel Digital Output Terminal – HD Series

EL2889 | Beckhoff | 16-Channel Digital Output Terminal

EL2889 is a high-density digital output terminal from Beckhoff.
It connects 24 V DC control signals to actuators.
The terminal offers 16 channels in a compact 12 mm housing.
It uses 1-wire connection technology for multi-channel actuators.
This terminal is short-circuit proof and has reverse polarity protection.

Description

Expert Review

“The EL2889 excels in space-critical cabinets. Its 16 channels in 12 mm width are unmatched.
The ground‑switching design simplifies wiring for multi‑channel loads.
With 0.5 A per channel and short‑circuit protection, it is robust for industrial use.
I recommend it for high‑density output applications where reliability matters.”

Manager’s Insight

“Cost‑efficient and reliable. The EL2889 reduces cabinet space and wiring time.
Tool‑free connection cuts installation errors.
With ATEX approval, it covers both standard and hazardous areas.
A solid choice for OEMs and system integrators.”

Suitable Devices & Applications

• Devices: PLCs, IPC, EtherCAT master controllers.
• Applications:
  • Factory automation – conveyor control, sorting lines.
  • Machine building – valve and actuator control.
  • Packaging machinery – multi‑channel output switching.
  • Process automation – lamp and indicator control.

Frequently Asked Questions

• Can I mix load types on one EL2889?

  Yes – it handles ohmic, inductive, and lamp loads per channel independently.

• What happens during a short circuit?

  The output limits current to typ. < 7 A and self‑recovers after fault removal.

• Is the EL2889 compatible with 5 V signals?

  No – it requires 24 V DC nominal voltage.

• Do I need external fuses?

  No – each channel is internally short‑circuit protected.

• How do I wire solid vs. stranded wires?

  Solid wires: push in directly. Stranded: use a screwdriver to open the spring.

• Can I use it in a humid environment?

  Yes – up to 95% relative humidity (non‑condensing).

• What is the maximum cable length?

  Keep within 30 m for reliable 24 V DC switching.

Purchasing Guide

• Choose EL2889 if you need 16 outputs in a slim 12 mm housing.
• Verify your power supply – it draws 30 mA + load from power contacts.
• Check your cable type – use solid wires for tool‑free connection.
• For hazardous areas – the ATEX/IECEx version is approved.
• Stock availability – ships in 12‑24 hours via FedEx/UPS/DHL.
