General


The BM800 Series Signal Conditioner is a next-generation signal conditioning device engineered for industrial automation and control systems. With an ultra-thin 6.2mm profile, it saves over 50% of installation space compared to conventional products, making it an ideal solution for high-density cabinet installations.

Designed for DIN 35mm rail mounting, this series provides galvanic isolation between input, output, and power supply circuits (≥1500V AC), ensuring reliable signal transmission in electrically noisy industrial environments. The entire series features 1-channel input and 1-channel output architecture, with flexible configuration via DIP switches on most models.
