Information About EL1004
The EL1004 is part of the Beckhoff EL100x digital input terminal series, offering compact signal acquisition within modular EtherCAT architectures. It uses a Type 1/3 input specification and incorporates a 3 ms filter to eliminate switch bounce and ensure clean digital transitions. The module integrates easily with EtherCAT I/O stations and supports direct wiring of four 2-wire sensors through additional 24 V connection points. Typical usage includes machine control, distributed I/O systems, and industrial automation applications requiring reliable digital signal capture with fast fieldbus communication.
Key Features:
- Four digital inputs: Captures 24 V DC binary signals for EtherCAT systems.
- Integrated input filter: 3 ms filtering minimizes bounce and enhances signal stability.
- LED indication: Each channel includes a state LED for straightforward diagnostics.
- Electrically isolated transmission: Ensures reliable communication to higher-level controllers.
- Compact EtherCAT design: Fits seamlessly into modular Beckhoff I/O stations.
- Direct sensor connection: Supports four 2-wire sensors with additional 24 V terminal points.
- Type 1/3 input specification: Optimized for industrial digital sensing applications.
- Wide temperature tolerance: Operates in harsh environments from –25 to +60 °C.
The EL1004 delivers the reliability and precision required for distributed digital signal acquisition in modern EtherCAT-based automation systems.
