Title
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.
Features and Applications
Features
DIN35mm rail mountable with fixing clip for easy installation
0.96” OLED display with bilingual support
Ethernet port for high-speed, interference-resistant data transfer
MODBUS-RTU and MODBUS-TCP outputs
RS232 and RS485 can be used at the same time
Input: 4–6 x 350Ω resistive strain gauge sensors
Display resolution up to 200,000
Power: 24VDC ±1%, ≤10W
Operating temperature: -10°C~40°C (14°F~104°F); humidity: 10%~95% non-condensing
Mechanical: 90×84×42 mm, ABS flame-retardant housing, IP20
Max 6 independent ADC channels
Applications
Ideal for multi-channel industrial force measurement and weighing applications requiring up to 6 independent ADC channels, resistive strain gauge sensors, and high-speed Ethernet data transmission with good noise immunity.
