WXZJ-GZ20A Series Intelligent Bar Graph Digital Display Instrument

WXZJ-GZ20A Series Intelligent Bar Graph Digital Display Instrument

The core design philosophy of the WXZJ-GZ20A Series Intelligent Instrument is versatility, making it a new generation of intelligent universal digital (bar graph) display control instrument suitable for multiple signal inputs/outputs. It works in conjunction with thermocouples, RTDs, transmitters, sensors, and other instruments, and is applicable in industries such as metallurgy, power, petroleum, chemical, machinery manufacturing, heat treatment, and light industry. Users can set appropriate parameters via the setting keys to achieve indication, alarm, and output for various industrial parameters including pressure, temperature, flow, level, speed, voltage, current, and frequency. This instrument has strong anti-interference capability and is suitable for use in environments with significant power fluctuations. The power supply range is 100~260VAC/DC or 24VDC.
