BM200-DI Insulated Safety Barrier

The BM100 series signal isolators quickly and accurately measure electrical parameters such as current and voltage, as well as non-electrical parameters such as temperature and resistance, and convert them into a standard analog signal after isolation. They can be directly connected to pointer instruments and digital indicators and are also compatible with automatic control devices (e.g., PLCs), various A/D converters, and computer systems. They are widely used in the energy, railway, petrochemical, metallurgical, chemical, food, and warehousing industries, among others.
