ABB Panel 800 - PP836 Hardware and Installation

the factory automation system to achieve remote monitoring, data sharing and other functions.

USB port: 

Host type A (USB 1.1) and Device type B (USB 1.1) interfaces are available, of which the maximum output current of Host type A interface is 500mA. 

Users can connect external storage devices, such as USB flash drives, through the USB interface to facilitate data backup and transfer, 

and can also connect USB keyboards, mice and other devices to enhance the ease of operation of the device.

CF card slot: supports Compact flash type I and II memory cards, which can be used to expand the storage capacity 

of the device to meet the user's needs for project memory expansion, such as storing a large amount of historical data, configuration files and so on.

4. Storage and Clock

Application Flash: 

The device has 12MB of application flash memory (incl. fonts), which is used to store application programs and related data to provide 

the necessary software support for the normal operation of the device. 

In practical applications, this storage space can be used to store the device's control programme, interface display data, etc..

Real-time clock: 

The real-time clock has an accuracy of ±20 PPM and is subject to errors due to ambient temperature and supply voltage,

with a total maximum error of 1 min/month at 25°C and a temperature coefficient of -0.034±0.006 ppm/°C². 

Real-time clocks are essential for recording information such as the time of operation of equipment, the time of events, etc. 

In industrial production processes, accurate time recording helps to monitor and analyse the production process and trace the root cause of problems.

5. Power supply related parameters

Power supply voltage: the power supply is + 24V DC, the operating voltage range is 20 - 30V DC, 

this wider voltage range makes the device can adapt to different power supply environment, improve the applicability of the device. 

In some industrial sites, the power supply voltage may have certain fluctuations, 

PP836 can work stably in this voltage range to ensure the normal operation of the equipment.
