HD67507-B2 Industrial Modbus TCP to Modbus RTU converter with DIN rail mounting

Industrial Modbus TCP slave to Modbus RTU master converter, housing type B, DIN rail mount. On Modbus RTU side you can connect up to 240 devices on one HD67507 Converter.

The HD67507-B2 Modbus converter is a reliable industrial solution designed to integrate Modbus TCP master devices with one or more Modbus RTU slaves. Thanks to its DIN rail housing type B, the device is well-suited for installation inside control cabinets, ensuring secure and space-efficient deployment. It can handle up to 10 simultaneous Ethernet connections on the Modbus TCP side, offering flexibility for large networks. On the RTU side, it supports up to 240 connected devices, making it suitable for advanced building automation and industrial monitoring. The converter operates in extreme environments with a temperature range from -40°C to +85°C, ensuring high reliability even in demanding conditions. With a power supply range of 8…19VAC or 8…35VDC, it can be adapted to different industrial power systems. Integrators benefit from simple installation and configuration using the free SW67507 software.

From a technical perspective, the HD67507-B2 offers strong communication stability thanks to its opto-isolated serial ports, which ensure protection against electrical disturbances. It supports both RS232 and RS485 interfaces on the RTU side, providing flexibility for legacy systems as well as modern setups. The Ethernet interface supports 10Base-T / 100Base-T with autosensing, which simplifies integration with existing IT infrastructures. Its compliance with EMS EN 61000-6-2 ensures resistance to electromagnetic interference, a crucial factor in industrial plants where noise levels are high. The housing dimensions of 71 x 60 x 95 mm and a weight of approx. 200g make the converter compact, but its robust build quality ensures long-term operation. Such parameters make it an excellent choice for system integrators who need to connect multiple devices efficiently.

In real-world applications, the HD67507-B2 is widely used in industrial automation, energy management, HVAC systems, and smart buildings. Integrators can implement it for centralized data collection from distributed Modbus RTU sensors or meters and forward information to SCADA or cloud-based systems through Modbus TCP. The converter allows remote monitoring, diagnostics, and control, enabling predictive maintenance strategies that reduce downtime. Thanks to the simple configuration via SW67507 software, users can set communication parameters without deep programming knowledge, which saves time during commissioning. Its rugged design and wide operating temperature range make it suitable not only for indoor panels but also for harsh industrial environments. This flexibility ensures reliable operation in factories, warehouses, public buildings, and energy facilities.
