Beckhoff EL1809 16-Channel Digital Input Terminal

Description

The EL1809 is a high-density EtherCAT Terminal from Beckhoff, designed to acquire 16 digital input signals (24 V DC) in a compact form factor. By utilizing 1-wire connection technology, this terminal streamlines cabinet wiring for high-density applications. It is compliant with the EN 61131-2 Type 1/3 specification, ensuring reliable signal detection for both standard and high-impedance sensors. The terminal features an integrated input filter (3.0 ms) to suppress signal noise, making it an ideal choice for monitoring slow digital signals in complex automation systems.

Features

• High Density: 16 digital inputs in a 12 mm wide housing.
• 1-Wire Technology: Direct plug-in technique significantly reduces wiring time.
• Safety & Compliance: Fully compliant with CE, UL, ATEX, and IECEx standards for hazardous locations.
• Reliability: Galvanic isolation between the E-bus and field potential (500 V).
• Easy Maintenance: Signal LEDs provide quick visual status diagnostics for all 16 channels.

Installation Guidelines

• Mounting: The EL1809 clips directly onto a standard 35 mm DIN rail (EN 60715). Multiple terminals can be mounted side-by-side using the double slot and key connection system.
• Wiring: Supports solid and flexible conductors (0.08–1.5 mm²). Use a flat-head screwdriver to actuate the spring-loaded terminals.
• Stripping: Strip wires to 8–9 mm for optimal contact within the terminal block.
• Power Contacts: Note that the maximum current load for power contacts is 10 A. Ensure your power supply distribution adheres to this limit when cascading multiple terminal
