ABB PP875 is a 7-inch widescreen industrial touch panel belonging to the Panel 800 series. It serves as a human-machine interface matched with ABB 800xA and AC 800M control systems, and also connects with mainstream third-party automation devices. Featuring compact size, high brightness display and durable structure, it works steadily in narrow installation spaces and harsh industrial conditions.

PP represents panel operator interface. 875 is the model code of this compact touch panel in the series. The complete model is used for product identification, ordering and inventory management.

It adopts a 7-inch TFT LCD widescreen with standard resolution and 64K display colors. Equipped with four-wire resistive touch screen, it can be operated with gloves and has long service life. The display adopts LED backlight with high brightness and adjustable luminance. It uses high-performance ARM processor, equipped with large-capacity running memory and solid-state storage, and supports SD card for capacity expansion. The rated working power is 24 V DC with wide voltage input range. The operating temperature ranges from minus 10 degrees Celsius to 60 degrees Celsius, and the storage temperature ranges from minus 20 degrees Celsius to 70 degrees Celsius. It adapts to relative humidity from 5 percent to 85 percent without condensation. The front panel reaches IP66 protection grade and the rear part is IP20. The whole device is light in weight and compact in overall size.

It is fitted with one Ethernet port for network data transmission and supports common industrial Ethernet protocols. Two serial ports including RS-232 and isolated RS-422/RS-485 are provided to adapt to serial communication protocols. A USB port is reserved for connecting peripheral devices and program downloading. An SD card slot is used for data storage, backup and firmware upgrade. It has built-in real-time clock with battery backup to ensure accurate time recording.

It realizes real-time display of process data, flow charts and operation trends. It supports alarm prompting, query and confirmation, and records operation events with time stamps. It allows operators to adjust parameters, switch operation modes and send control commands on site. It completes data recording and historical trend query for production analysis. It supports project configuration, program downloading and online modification through professional engineering software. It runs smoothly and provides multi-language display function.

It is widely used as on-site operation panel for various production equipment in machinery manufacturing, automobile and pharmaceutical industries. It applies to water treatment, food processing and small and medium power industries for local monitoring and control. It is suitable for HVAC and building automation systems as well as various infrastructure control sites. It is the preferred device for industrial sites with limited installation space and high requirements on display brightness.

Install the panel in the reserved opening of control cabinet and fix it with matched accessories, and guarantee good ventilation around. Use shielded wires for communication wiring, and keep power lines and signal lines separated to avoid interference. Complete project configuration and program download before formal operation, and no on-site calibration is needed. Inspect the sealing performance of front panel, touch screen and all wiring connections regularly. Clean the screen with mild detergent, and do not use corrosive chemicals. The internal components cannot be maintained on site, replace the whole device when faults occur. Keep the equipment dry and at proper temperature during idle storage.
