The EP2338-0002 is a compact, high-performance EtherCAT Box module designed for distributed industrial automation applications. This IP65/66/67-rated module features 8 digital channels, which can be configured as either digital inputs or digital outputs, providing extreme flexibility in machine control architectures. The EP2338-0002 communicates via the high-speed EtherCAT protocol and connects via robust M8 and M12 industrial-grade connectors. It is engineered for harsh environments, offering high vibration/shock resistance and a wide operating temperature range (-25 to +60 Celsius). Each output channel is individually short-circuit proof, capable of handling ohmic, inductive, or lamp loads up to 0.5 A, making it ideal for decentralized sensor and actuator integration.

Installation Guidelines
Mounting: Use the two 3.5 mm diameter fixing holes to secure the module directly onto the machine frame. M3 screws are recommended.
Connections: The EtherCAT bus interface utilizes two M8 shielded sockets. Ensure shielded cables are used to prevent interference in high-EMI environments.
Power Supply: Connect the 24 V DC load voltage via the M8 power interface. The module provides a downstream connection M8 female socket for daisy-chaining power to subsequent EtherCAT Box modules.
Hazardous Areas: When installed in areas rated II 3 G Ex nA IIC T4 Gc, ensure that all connections are made in a de-energized state and that cabling meets the appropriate non-incendive wiring standards.

FAQ
Are the 8 channels fixed as input or output?
The 8 channels on the EP2338-0002 are configurable, meaning they can be assigned as either digital inputs or digital outputs depending on your application requirements.
What is the protection rating of this module?
The module is rated IP65, IP66, and IP67, making it suitable for environments exposed to dust and water spray.
Can I daisy-chain the power supply to other modules?
Yes, the module includes both an M8 male input socket and an M8 female downstream connection socket to facilitate power distribution to additional modules.
What is the typical switching time for the outputs?
The typical turn-on time (TON) is 50 µs and the turn-off time (TOFF) is 100 µs.
