Description

The BECKHOFF ER2338-1002 is a digital EtherCAT Box designed for decentralized industrial automation applications. Functioning as a compact input and output module, it features 8 digital channels that can be freely configured as either inputs or outputs to match specific machine and process requirements. Housed in a robust module enclosure with IP65, IP66, and IP67 protection ratings, this device is engineered for direct machine-level mounting without requiring a control cabinet.

Communication is handled via the high-speed EtherCAT protocol, connecting through dual shielded M8 sockets with screw-type locking. Power supplies are routed independently for system electronics and field loads, utilizing M8 connectors for feed and downstream connections. With support for standard 24 V DC sensor and actuator supplies, the ER2338-1002 integrates seamlessly into distributed control topologies requiring reliable signal acquisition and switching in harsh industrial environments.

Features

• 8 digital channels, freely configurable as inputs or outputs

Installation Guidelines

1. Verify the exact model number (ER2338-1002) and inspect the module housing and connectors for any transport damage before installation.
2. Ensure all associated power supplies and field voltage sources are completely de-energized before mounting or wiring the device.
3. Mount the EtherCAT Box securely onto a flat machine surface or mounting plate using appropriate hardware in a variable installation position as required.
4. Connect the EtherCAT network cables to the shielded M8 bus sockets and secure the screw-type connections properly.
5. Connect the 24 V DC power supply feeds to the M8 power connectors, ensuring correct polarity for the feed and downstream lines.
6. Connect field sensors and actuators to the M12 A-coded input/output ports according to the application configuration.
7. Power on the system and verify operational status via the diagnostic indicators and the master controller configuration.
