DQ-309H Digital Transmitter – 6-Channel High-Speed Ethernet Weighing Transmitter with MODBUS Support

DQ-309H Digital Transmitter – 6-Channel High-Speed Ethernet Weighing Transmitter with MODBUS Support

Product Description:

The DQ-309H digital transmitter is a high-performance, multi-channel device for precise force and weight measurements in industrial systems. It accepts analog resistive strain gauge sensors (output range: -3mV/V to 3mV/V) and supports up to six independent ADC channels, allowing connection of 4–6 pieces of 350Ω load cells. The unit features a 0.96-inch OLED display (user-selectable Chinese or English), four membrane buttons for configuration, and multiple communication interfaces including Ethernet, RS232, and RS485 (usable simultaneously). With MODBUS-RTU and MODBUS-TCP protocols and robust anti-interference capabilities, the DQ-309H ensures stable, high-speed data transmission in electrically noisy environments.
