Description
Designed for decentralized industrial automation in high-hygiene and washdown areas, the BECKHOFF EQ1809-0022 offers direct acquisition of digital control signals from sensors in demanding process environments. This stainless steel EtherCAT Box features 16 digital inputs and is optimized for direct installation on machinery without requiring a protective control cabinet.
With its robust construction, the module stands up to aggressive cleaning agents and high-pressure washdown procedures. The device couples directly to EtherCAT networks via shielded M8 connections, transmitting digital signals with high speed and deterministic timing to the master PLC. The dual-channel design of the M12 input sockets allows for high-density sensor wiring in a compact physical footprint.
Features
- 16 digital inputs integrated into a compact, decentralized module.
- Robust stainless steel housing specifically engineered for hygienic applications.
- IP69K protection rating allowing direct contact with high-pressure cleaners.
- Flexible signal acquisition compliant with EN 61131-2 Type 1 and Type 3 specifications.
- Short-circuit protected sensor power supply derived from the load voltage feed.
- Status and diagnostic LEDs for rapid local troubleshooting.
Applications
- Food and beverage processing lines requiring strict washdown protocols.
- Pharmaceutical packaging and chemical formulation plants.
- Cleanroom production systems and semiconductor manufacturing.
- On-machine mounting in wet or highly corrosive industrial environments.

Installation Guidelines
- Mount the module directly to flat mechanical structures using the 2 integrated fixing lugs designed for M5 screws.
- Ensure all unused M12 and M8 connections are sealed with appropriate stainless steel blanking caps to maintain the IP69K liquid-tight seal.
- Use shielded cabling for EtherCAT bus links and connect shielding to the metallic M8 connector housing for optimum EMC performance.
- Do not exceed the cumulative sensor supply limit of 0.5 A across all 16 channels to avoid triggering the internal short-circuit protection.
