PID Control monochrome/color paperless recorderDetailed product description：

PID control monochrome/color paperless recorder

The monochrome instrument adopts a 5.4-inch 160 × 128 dot matrix LCD graphic display screen as the display, with LED backlight, rich picture, and large information content; High speed, high-performance microprocessors that can detect, record, display, and alarm signals; Using high-capacity FLASH flash memory chips to store historical data, never losing data in case of power failure; Fully isolated universal input, capable of inputting multiple signals without the need for hardware replacement, can be configured through instrument configuration
The color instrument panel uses a 5.4-inch 320 × 240 dot matrix TFT high brightness color graphic LCD screen as the display, with clear backlit images, vibrant colors, and a wide viewing angle. Expanded the large capacity storage area and improved communication speed

It can accept two tested signals and has two analog control outputs, completing the entire process from signal acquisition, control, recording, retrieval to transmission according to user requirements.
The built-in PID algorithm can output corresponding adjustment signals.
It can be directly connected to a printer with an RS-232C serial port to complete instant printing. The serial communication interface can transmit data with the upper computer, achieving centralized management of recorded data
Equipped with manual data transfer function, optional 128M, 256M, 512MCF card storage card transfer history
