Beckhoff EL1809 EtherCAT Terminal 16-Channel Digital Input, 24V DC, 3 ms Filter, 12×100×68 mm

Overview

The Beckhoff EL1809 EtherCAT Terminal acquires sixteen 24 V DC binary input signals and forwards them galvanically isolated to the controller. Each channel has an LED status indicator. With a built‑in 3 ms input filter, the EL1809 effectively suppresses bounce from mechanical switches while providing high channel density in a 12 mm housing.

Key Features

• 16-channel 24 V DC digital input in compact 12 mm width
• 3 ms input filter for bounce suppression (EN 61131-2 type 1/3)
• 1‑wire connection; reference ground is the 0 V power contact
• Electrical isolation between E‑bus and field potential (500 V)
• Tool‑free direct plug‑in technique for solid conductors
• Approvals: CE, CCC, UL, ATEX, IECEx

Applications

• General-purpose 24 V DC signal acquisition in EtherCAT systems
• Panels requiring high input density with debounce filtering
