Description

The BECKHOFF EL1889 digital input terminal is designed to acquire binary control signals from the physical field level and transmit them to the higher-level automation controller via the EtherCAT network. Featuring a highly compact High Density (HD) housing, this terminal provides sixteen distinct input points within a 12 mm physical width to optimize control cabinet space utilization.

This terminal is built for 1-wire connection technology and operates with ground-switching (sinking) sensors. The BECKHOFF EL1889 processes 24 V DC signals, identifying a logical "1" status at low voltage levels (0 to 7 V) and a logical "0" status at higher voltage levels (18 to 30 V). High-density connection terminals allow direct wiring of solid-wire conductors without additional tools, facilitating efficient high-density installations.

Features

Provides 16 digital input points in a compact 12 mm housing width
Engineered for ground-switching (sinking) input characteristics
Utilizes space-saving 1-wire connection technology
Equipped with integrated signal status LEDs for each input channel
High Density (HD) terminal design with toolless direct plug-in connection for solid conductors

Applications

High-density distributed input/output configurations within automated machine environments
Direct integration with ground-switching (sinking) proximity sensors, limit switches, and photoelectric sensors
EtherCAT-based control systems demanding high-density signal acquisition within limited cabinet space

Installation Guidelines

Ensure the entire industrial control system and power supplies are completely de-energized before mounting or wiring the terminal.
Mount the terminal onto a standard 35 mm DIN rail conforming to EN 60715, securing it using the integrated locking mechanism.
Slide successive terminals together using the double slot-and-key design to ensure correct E-bus and power contact engagement.
Connect the solid wiring by pushing the conductor directly into the plug-in terminal point. For fine-stranded conductors, press the spring actuator down with a screwdriver before inserting the wire.
Ensure field power voltage is correctly configured within the nominal 24 V DC tolerance range before turning on the power.

FAQ

What type of sensor logic is compatible with the BECKHOFF EL1889?

The BECKHOFF EL1889 is designed specifically for ground-switching (sinking) logic, which registers a logical "1" signal state when the voltage is pulled down to between 0 and 7 V DC, and a logical "0" state when the voltage is between 18 and 30 V DC.

How many input channels are available on the BECKHOFF EL1889?

The BECKHOFF EL1889 provides exactly 16 digital input channels housed within a compact 12 mm wide High Density (HD) terminal block.

What wiring method is supported by the BECKHOFF EL1889?

The BECKHOFF EL1889 supports 1-wire connection technology. Solid wire conductors can be inserted directly into the plug-in connection points without tools, while stranded or ferruled wires are secured by engaging the integrated terminal spring with a standard screwdriver.

What is the input filter time of the BECKHOFF EL1889?

The BECKHOFF EL1889 features a typical input filter delay time of 3.0 ms to ensure robust signal filtering and prevent false switching from electrical noise or contact bounce.

Does the BECKHOFF EL1889 require software address configuration?

No, the BECKHOFF EL1889 does not require any manual hardware address or parameter configurations, as addressing is automatically handled during standard startup via the EtherCAT network.
