This state-of-the-art system boasts a high-speed, high-performance 32-bit ARM microprocessor, ensuring exceptional precision in 16-way signal detection, recording, display, and alarms. The 3.5-inch 320x200 dot-matrix high brightness graphic LCD display offers crystal-clear visuals and a wide viewing angle. The newly designed silicone buttons provide simplicity and comfort, with built-in microswitches for an extended service life.

The system features a 1.2mm transparent acrylic window with surface hardening treatment, ensuring remarkable anti-scratch resilience. With all-isolated all-purpose inputs, there's no need for jumpers; you can configure them via software. The switching power supply works seamlessly within the range of 100VAC to 240VAC.

An integrated hardware real-time clock keeps time accurately even in power-down situations. The system provides a 24VDC isolated power distribution for transmitters, ensuring efficient operation. Large-capacity FLASH memory chips store historical data without any loss during power-down.

This system also includes four relay alarm outputs and supports various standard signals like DC current, DC voltage, frequency, millivolt, thermocouple, and RTD. The signal full scale accuracy is an impressive ±0.2%, and it offers a standard 4-20mA transmitter output.

The software offers robust security features, ensuring user configuration safety with software locks. You can easily configure and display engineering bit numbers and units with a Chinese menu. The system allows a wide range of engineering quantities display, from -9999 to 30000, supporting scientific notation and vacuum operation.

You can set upper and lower limits for each channel, with records and display for the most recent 15 alarm events. Additionally, each channel supports flow accumulation functions, with various report options such as hourly, 8-hour, 12-hour, daily, and monthly reports.

Choose between horizontal or vertical curve display modes, and take advantage of the built-in GB231 secondary character font (6500 characters). The system incorporates a powerful T6 input method that accommodates Pinyin, digital, English, special symbols, and more, adhering to international standards for unit input.

Communication is a breeze with standard Ethernet, RS232C, and RS485 interfaces. It supports Modbus-RTU communication and is compatible with various professional configuration software, eliminating the need for special drivers. Additionally, the system features a USB2.0 interface for data backup, with support for FAT32 file systems. You can connect an external mini-printer for on-site printing of data and curves.
