Intelligent touring detection alarm

It can input sensor and transmitter signals such as thermal resistance, thermocouple, DC current, DC voltage, etc. The basic error is less than 0.2%FS, and the display range is -1999~9999. Each channel independently sets the input signal type, range, and alarm value. Each channel independently sets the digital filter time constant, which effectively improves the anti-interference ability. Each channel independently sets the zero point and full scale. Correction to effectively reduce the sensor and transmitter signals such as thermal resistance, thermocouple, DC current, DC voltage and so on. The basic error is less than 0.2% F·S, and the display range is -1999~9999. Each channel independently sets the input signal type, range, and alarm value. Each channel independently sets the digital filter time constant, which effectively improves the anti-interference ability. Each channel independently sets the zero point and Full-scale correction can effectively reduce sensor error and improve system measurement accuracy. Level 2 parameters of unused channels can be arbitrarily closed. The second level parameters are controlled by a password to prevent misoperation. Equipped with parameter copy function, which greatly reduces the workload of parameter setting. Unique and practical alarm function, which can be connected with XSLCU multi-point control unit to realize the alarm output of each channel. Manual, timing, and alarm start printing. Fast and efficient communication interface, greatly shortening communication time
