This product is a digital isolation transducer for DC voltage acquisition and measurement . It can be used to measure the voltage in DC circuit. The ratio dynamic range can be up to 1000: 1 with high-precision 24-bit dedicated AD chip. By using the resistive voltage-dividing and resistance sampling measurement principle, it has high accuracy, good stability and high communication speed, the completely isolated processing technology is with anti-interference ability. Measurement of electrical parameters through the RS-485 digital interface output to achieve long-distance transmission, the product MODBUS protocol is complete compatible with a variety of configuration software or PLC equipment MODBUS (RTU) protocol. It can be applied to power, room monitoring, industrial measurement and other fields.Data Sheet
