Industrial Modbus slave to HART master converter

Industrial Modbus slave to HART master converter

HD67908-A1 is a compact Modbus RTU slave to HART master converter in a slim Type-A housing for DIN-rail mounting.

It enables PLC, SCADA, or supervisory systems to monitor and read data from HART-enabled sensors and transmitters over a Modbus RTU network. The device supports both digital HART communication and a standard 4–20 mA analog input, allowing access to process values and extended diagnostics at the same time.

Designed for harsh industrial environments, HD67908-A1 operates from -40°C to +85°C, is easy to install in crowded panels, and offers flexible power supply (8–19 VAC / 8–35 VDC). Configuration is quick and simple using the free SW67908 software, making integration fast and reliable across process, water, energy, and HVAC applications.
