Description
Designed for decentralized industrial automation, the BECKHOFF EP2008-0022 EtherCAT Box enables the direct processing of binary control signals. This highly robust, machine-mountable I/O module features 8 digital outputs, each operating at 24 V DC and capable of switching load currents up to 0.5 A. Engineered for harsh industrial environments, it features a rugged, fully sealed IP67 enclosure that allows for installation directly on machinery, completely eliminating the need for protective control cabinets.
The EP2008-0022 interfaces with actuators through standard M12 connectors, providing 1 output per M12 socket. The high-speed EtherCAT protocol connection is established via shielded M8 screw-type connectors, ensuring rapid, reliable data transmission and optimal electromagnetic immunity in noise-heavy manufacturing zones.
Features
- 8 digital outputs (24 V DC) for direct connection to actuators, solenoids, or indicators.
- Robust IP65, IP66, and IP67 protection class ratings for harsh on-machine environments.
- Individually short-circuit proof outputs with automatic overload protection.
- M12 connection technology (5-pin, A-coded) with 1 output allocated per socket.
- High-speed EtherCAT bus interface using 2 x M8 shielded screw-type connections.
- LED indicators for diagnostic monitoring of channel state, power supply, and bus communication.
- Direct, cabinet-free mounting to minimize cabling and integration time.
Applications
- Pneumatic and hydraulic valve terminal control
- Material handling and conveyor systems
- Robotic end-of-arm tooling and assembly lines
- Automotive manufacturing cells
- General distributed machinery and industrial packaging

Installation Guidelines
-
Mounting: Attach to a flat surface using integrated mounting holes. Ensure maximum structural stability to maintain vibration resistance.
-
Torque: Apply specified torque to M8 and M12 connectors to guarantee dust- and moisture-tight IP67 sealing.
-
Grounding: Connect functional earth (FE) to the machine chassis via the mounting surface or via M12 pin 5 to minimize noise interference.
-
Cabling: Keep signal cables separated from heavy power cables to prevent electromagnetic cross-talk.
