Product Description

Q5780 series eight-loop digital display controller adopts the surface mounting technology and is produced by fully-automatic placement machine, which has strong anti-interference ability. The instrument supports a variety of signal inputs, and can be used with various types of sensors and transmitters to realize the measurement and display of physical quantities such as temperature, pressure, level, speed, force, etc. The instrument can display eight measurement signals at the same time, and it can be used with two unified alarms, eight separate alarm outputs, one optional variable output function, RS485/232 communication, drive printing and other output functions, and it is suitable for systems that need to carry out multi-measurement point detection. Detection of the system for multiple measurement points
