DC multi-parameter digital transducer
HOME > Multi-parameter > DC Multi-parameter Digital Transducer
This product is a 1-phase DC power acquisition measurement intelligent isolation transducer. It can measure the current, voltage, power and electrical of the DC circuit. Using high-precision 24-bit dedicated AD chip, the ratio dynamic range can be up to 1000: 1. Hall measurement principle or resistance sampling measurement principle is with high accuracy, good stability and high communication speed, the completely isolated processing technology is with anti-interference ability. Measurement of electricity 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.
