RS485 isolator

DC voltage

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. Features Available with wide power supply: DC: 10-30V or 10-55V or AC/DC: 85-265V. With odd parity, even parity, no parity, 2 stop bits and other communication methods are free to set. Communication speed optional, the maximum communication speed to 115200 bps. The intelligent transducer with the smallest size and wide current measurement range in the peer. Electroplating has a positive and negative cumulative function, and power-down storage function. With red and green light-emitting diode instructions function, the red light indicates the normal operation of the product (100mS flashing), the green light indicates the product communication. High anti-interference ability, the input, output and power port to resist the surge voltage up to 2KV or more.
