Information About EP1809-0021
The Beckhoff EP1809-0021 EtherCAT Box is a 16-channel digital input module designed for decentralized installation directly in the field. It transmits binary control signals from the process level to the controller with electrical isolation and high reliability. Its 3.0 ms input filter is optimized for mechanical and electronic signals, providing hardware-based debouncing for stable signal acquisition. All connections are made via M8 screw-type connectors, ensuring robust and secure field wiring. With an IP65/66/67 protection rating, the EP1809-0021 withstands exposure to dust, water, and vibration, making it ideal for use in industrial automation, machinery, and outdoor applications. Additionally, the integrated LED indicators on each channel provide immediate visual feedback for operational status and troubleshooting.
Key Features:
- 16 Digital Inputs: Compact module for capturing binary signals directly from the process level.
- 24 V DC Operation: Standard industrial voltage ensures compatibility with common sensors and control devices.
- M8 Connectivity: Features 16 M8 input connectors and 2 M8 sockets for EtherCAT bus and power connections.
- Input Filter 3.0 ms: Provides debouncing for mechanical and electronic signals to ensure signal stability.
- Short-Circuit Proof Sensor Supply: Integrated 0.5 A output for powering connected sensors safely.
- Electrical Isolation: 500 V isolation between I/O and system bus for safe and reliable operation.
- LED Diagnostics: Each input channel includes LED status indication for active signal monitoring.
- Compact Industrial Design: Only 26.5 mm thick, suitable for installation in tight control spaces.
- High Protection Class: IP65/66/67 housing resists dust, moisture, and environmental stress.
- Durable Material: Constructed from reinforced PA6 polyamide for mechanical and chemical resistance.
The EP1809-0021 delivers the reliability and precision required for distributed signal acquisition, industrial I/O applications, and robust EtherCAT-based automation networks.
