XDB904 Programmable Analog High Precision Digital Display Meter
Features
● Free-to-set display and output correspondence, easy to copy frequency/speed/pressure/opening;
● Output 0-10V, 0-20mA, 2-10V, 4-20mA can be directly selected;
● All parameters are saved after power failure. "Given output" can select whether to save after power failure (set by F0-8);
● Multiple given modes can be selected. Check FO-2 parameter for details;
● Convenient for applications requiring slow changes;
● Add automatic operation function, one key off output and other functions.
Applications
● Cooperate with various analog output sensors and transmitters;
● Measurement, transformation, display;
● Control of temperature, pressure, liquid level, composition and other physical quantities.
● XDB 904 digital display meter designed for displaying physical quantities such as temperature, pressure, and liquid level.
Technical Parameters
