1、 Product Introduction
The LD-RH1000 series paperless recorder is a 1-15 input LCD display paperless recorder, which uses a 32-bit high-end processor based on ARM core to achieve high-speed information acquisition and processing. The 32M large capacity flash memory chip can achieve ultra long time data storage. The LD-RH1000 series paperless recorder can input signals such as standard current, standard voltage, thermocouple, thermistor, etc. It has functions such as sensor isolation and distribution, relay output, temperature and voltage compensation, historical data transfer and remote communication.
2、 Functional Features
1. 5.1-inch 240X128 dot matrix graphic LCD display screen, LED backlight, rich image, and large amount of information;
2. Adopting ARM based high-speed and high-performance microprocessors, it can simultaneously detect, record, display, and alarm 8 signals;
3. Using high-capacity FLASH flash memory chips to store historical data, storing data beyond normal times, and never 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.
