1、 Overview of Printing Integrated Paperless Recorder
This paperless recorder is integrated with a micro printer, with a user-friendly interface and easy operation. Suitable for on-site printing needs, meeting customers' requirements for both recording and printing, and adapting to various complex working conditions. It is also possible to copy data to a computer for viewing. This recorder has no pen or paper recording, and the daily maintenance workload is very small, with low operating costs; The recorder adopts an imported 5.6-inch 320 * 240 dot matrix TFT high brightness graphic LCD display screen, which has the characteristics of clear picture, stable performance, brilliant colors, wide viewing angle, and long service life;
2、 Main features of integrated paperless recorder for printing
1. No pen, no paper recording, very little daily maintenance workload
2. Adopting imported TFT 5.7-inch 320 * 240 dot matrix graphic LCD display screen with high brightness LED backlight
3. Adopting a high-speed and high-performance 32-bit ARM microprocessor, the screen response time is less than 0.5 seconds, and it can simultaneously achieve 16 signal acquisition, recording, display, and 12 alarm channels
4. Using a 256M large capacity FLASH flash chip to store historical data, never losing data in case of power failure;
5. Fully isolated universal input, capable of inputting multiple signals simultaneously without the need to replace modules
6. The numerical range for displaying engineering quantity data is wider, and it can display 4-digit values: -999~9999;
7. Can be configured to display: engineering tag number, engineering unit, flow accumulation
8. Support clipboard, capable of copying and pasting parameters
9. It can support 12 channels of 3A electrical output, and the screen can have flashing alarm display. At the same time, it can set the lower and upper limits, lower limits, upper limits, and upper limits of each channel alarm;
10. 16 channel temperature and pressure compensation, supporting compensation signal input and optional constants, can provide various compensation models such as superheated steam, saturated steam, pressure compensation, etc
11. Supports external micro printers for manual printing of data and curves, and supports on-site printing by users
12. Can provide standard USB interface, supporting USB 1.1 and 2.0 USB drives,
13. Electricity can provide standard serial communication interfaces: RS485 and RS232C, supporting Modbus RTU protocol;
14. Adopting a new type of switching power supply, it can work normally within the range of 85VAC~264VAC and 47-63HZ of AC power supply
15. Can provide 16 sets of transmitters+24VDC (≤ 40mA) isolated power distribution
16. The instrument integrates hardware real-time clock, which can run accurately even in the event of power failure
17. The all aluminum sealed shell and internal shielding plate can work normally in harsh environments.
