HD67E52-5-A1 EtherCAT Master to Modbus RTU Slave RS485 – industrial protocol converter

Industrial EtherCAT Master to Modbus RTU Slave RS485 converter.

HD67E52-5-A1 is an industrial protocol converter designed to integrate EtherCAT Master systems with devices operating as Modbus RTU Slave over RS485. The device enables centralized EtherCAT control while simultaneously exposing process data to Modbus RTU-based monitoring or control systems.

The converter operates as an EtherCAT Master, managing communication within the EtherCAT network, while at the same time acting as a Modbus RTU Slave on the RS485 serial bus. This architecture allows modern EtherCAT-based automation systems to be seamlessly integrated with applications where Modbus RTU is used for supervision, data acquisition, or control.

The HD67E52-5-A1 model is equipped with two RJ45 Ethernet ports featuring an internal EtherCAT switch, enabling EtherCAT input and output connection within the same network line. The Modbus RTU interface is implemented via a 3-pin 5 mm terminal block supporting RS485 communication, ensuring stable data transmission over longer distances.

Thanks to its industrial-grade design and high environmental resistance, the converter operates reliably across a wide temperature range from -40°C to +85°C. The use of industrial components ensures stable and long-term operation in demanding automation and infrastructure environments.

Device configuration is performed using the dedicated SW67E52 software. The tool enables configuration of EtherCAT and Modbus RTU parameters, data mapping, and preparation of the device for operation within the target control system.
