Description
Facilitate seamless bidirectional data transmission between serial devices and high-level control architectures using the Beckhoff EL6002 EtherCAT terminal. This 2-channel serial communication interface enables the direct connection of up to two serial RS232 devices to the standard EtherCAT network. It integrates smoothly into decentralized systems, permitting flexible configuration of transmission parameters such as baud rate, parity, and stop bits directly via the EtherCAT master controller, eliminating the need for manual DIP switch configurations.
The unit features 500 V electrical isolation between the E-bus backplane and the RS232 signal lines to prevent ground loop damage and signal degradation in demanding industrial settings. Packaged in a compact housing, this module contains internal data buffers to ensure reliable asynchronous data transfer even under heavy system load.
Features
- Two independent serial RS232 communication channels.
- Standard 9-pin D-sub connectors for reliable physical terminal interface connections.
- Flexible data transfer rates ranging from 300 to 115,200 baud.
- Integrated data buffer with 864 bytes of receive buffer and 128 bytes of transmit buffer.
- Direct power supply routing through the E-bus backplane.
- Compact 24 mm housing with built-in signal status LEDs for simplified on-site diagnostic checks.
Applications
- Integrating serial barcode readers, weight scales, and labeling machines.
- Connecting legacy human-machine interfaces (HMIs) to EtherCAT systems.
- Interfacing custom manufacturing instruments and specialized process sensors.
- Decentralized industrial automation and general machinery control.

Installation Guidelines
- Mount the module onto a standard 35 mm DIN rail conforming to EN 60715 using the locking mechanism.
- Ensure proper side-by-side terminal mounting by utilizing the double slot and key connection mechanics.
- Observe IP20 protection guidelines; prevent moisture, excessive dust, and conductive particles from entering the enclosure.
- Prior to wiring or installation, isolate the electrical system from all live power sources.
