HRT-227CS – HART to Single Mode Fiber Converter

Introduction: The HRT-227CS is a robust industrial converter that bridges HART communication over long distances using single-mode fiber optics. It is ideal for environments requiring noise immunity and extended communication range, such as petrochemical plants, tunnel monitoring, and building automation. It supports both HART master and slave modes and is compatible with up to 15 HART devices.
