Description

The BECKHOFF ER1819-0022 is an industrial-grade EtherCAT Box designed for the direct acquisition of digital signals from field-level sensors. Featuring 16 digital inputs, this module processes binary control signals and transmits them to the higher-level controller via EtherCAT. Its mechanical design features a heavy-duty zinc die-cast housing, making it highly suitable for decentralized installations directly on machines and equipment where space is limited and environmental conditions are demanding.

Equipped with 5-pin, A-coded M12 sockets for signal connection and M8 sockets for power and EtherCAT interfaces, the BECKHOFF ER1819-0022 eliminates the need for separate protective enclosures. The device supports Type 1/3 sensor interfaces according to EN 61131-2 and features a fast 10-microsecond input filter to ensure high-speed, reliable data processing in fast-cycle automation tasks.

Features

• 16 digital inputs compatible with Type 1 and Type 3 sensor characteristics according to EN 61131-2.
• Fast input filter of 10 microseconds for responsive signal capture.
• Zinc die-cast housing providing protection ratings up to IP67.
• Standardized M12 connection technology utilizing 5-pin, A-coded sockets.
• M8 shielded screw-type connectors for secure EtherCAT bus communication.
• Short-circuit proof sensor supply generated directly from the control voltage.
• Electrical isolation of 500 V to protect downstream network components.

Applications

• Decentralized machine control architectures requiring I/O integration without control cabinets.
• Conveyor systems, packaging machinery, and material handling lines.
• Robotic assembly systems requiring lightweight, direct-mounted sensor interfaces.
• High-vibration assembly lines where traditional terminal blocks are impractical.

Installation Guidelines

1. Pre-Installation Check: Verify the physical condition of the BECKHOFF ER1819-0022 and ensure all seal rings on the M12 and M8 connections are intact.
2. De-energize: Disconnect all power sources from the system before initiating mounting or wiring operations.
3. Mounting: Attach the module to a flat mounting surface using the designated 3.5 mm (for M3) or 4.5 mm (for M4) fixing holes. Ensure the metal housing makes good contact with a grounded mounting surface if possible.
4. Cabling: Connect the M12 sensor cables and M8 EtherCAT communication lines. Ensure all unused sockets are fitted with protective caps to maintain the IP67 protection rating.
5. Power Supply Connection: Wire the M8 power feed socket. Check the voltage levels to verify they fall within the 24 V DC (-15% / +20%) tolerance range.
6. Commissioning: Power up the controller, scan the module in the TwinCAT System Manager, and verify that the status LEDs indicate normal EtherCAT operation.
