The Q5200 series dual circuit digital display controller adopts a fully automatic chip mounting packaging process, which has strong anti-interference ability. Designed a dual screen LED digital display, providing richer display content. It can be used in conjunction with various sensors and transmitters to achieve measurement and display of physical quantities such as temperature, pressure, liquid level, speed, flow rate, etc. The output functions include alarm control, analog transmission, RS485/232 communication, and more. Compared to traditional digital instruments, it also adds functions such as restoring factory default values, transmission output, and light column can be set separately. The upper and lower window display content can be freely set, and mathematical calculation functions can be customized, It can perform addition, subtraction, multiplication, and division operations on two measurement signals. The menu is clear and concise, and the operation is simple. It is widely used in automatic control systems for temperature, pressure, flow, liquid level, etc. in industries such as machinery, chemical industry, ceramics, light industry, metallurgy, petrochemical, and heat treatment.
