Industrial Modbus Slave to Slave Converter with galvanic isolation

Industrial Modbus Slave to Modbus Slave Converter, housing type A (slim), DIN rail mount.

The HD67147-A1 is a professional Modbus Slave to Modbus Slave converter designed to allow the sharing of information between two different Modbus Masters. This device acts as a transparent communication bridge, making it possible to replicate registers and statuses between two independent supervisory systems without the risk of conflicts. Thanks to its compact slim type A housing, the converter is particularly suitable for installations in control cabinets where space is limited. It is mounted on a standard 35 mm DIN rail, ensuring compatibility with most industrial enclosures.

One of the key advantages of the HD67147-A1 is its ability to manage up to 4000 Modbus Registers and up to 4000 Modbus Status points. This makes it a highly flexible solution for complex automation systems requiring large amounts of process data exchange. The converter provides galvanic isolation between the two Modbus ports, protecting both the communication lines and connected equipment from electrical disturbances or ground loops. Its extended operating temperature range of -40°C to +85°C makes it suitable for harsh industrial environments, including outdoor and heavy-duty applications.

The configuration of the device is straightforward using the free SW67147 software. With this tool, users can define communication parameters for each RS485 or RS232 port, adjust register offsets, and configure the data mapping according to system requirements. The device supports communication speeds of up to 115200 bit/s on both RS232 and RS485 interfaces, ensuring stable and fast data exchange. Its lightweight design (approx. 200 g) and compact dimensions of 120 x 23 x 107 mm make it easy to integrate into existing setups. The 24-month manufacturer’s warranty further guarantees reliability and long-term use in industrial environments such as SCADA systems, building automation, and energy monitoring networks.
