Intelligent multi-channel color paperless recorder

Intelligent multi-channel color paperless recorderAdopting a 32-bit high-end processor based on ARM core, high-speed information acquisition and processing are achieved, and a 128M large capacity flash memory chip can achieve ultra long time data storage.

Features
1. 5.6-inch 320X234 dot matrix TFT true color graphic LCD display, available in various styles such as 7-inch and 10 inch, with touch operation, CCFL backlight, clear image, vibrant colors, and wide viewing angle.
2. By using ARM based high-speed and high-performance microprocessors, it is possible to simultaneously detect, record, display, and alarm 8 signals.
3. Using a large capacity FLASH flash chip to store historical data, storing data for abnormal times, and losing data in case of power failure.
4. Fully isolated universal input, capable of inputting multiple signals without the need for hardware replacement, can be configured through instruments.
5. The displayed numerical range of the engineering quantity is wide, and the cumulative value can reach 4294967295.
6. Chinese menu configuration, display channel number, engineering unit, flow accumulation, temperature and pressure compensation, software password lock to protect user configuration security;
7. Alarm display, indicating the lower and lower limits, lower and upper limits, and upper and upper limits of each channel alarm simultaneously;
8. High display accuracy: The basic error for displaying numbers, curves, and bar charts is ± 0.5% FS.
9. Data transfer, using USB interface storage to backup or transfer historical data.
10. Standard serial communication interface: RS485 or RS232.
11. Can be connected to an external micro printer to meet the on-site printing needs of users.
12. Metal casing, allowing for use in harsh environments.
