The standard series of Panel 800 includes PP875, PP881, PP883, PP886, and PP895, designed for cost-effective, safe, and efficient monitoring and control of complex HMI applications. These panels are available through 7 “, 10.1” 12.1 “, 15.4”, and 21.5 The high-resolution wide screen, faster access to multiple applications, and easy-to-use touch screen interface of TFT/LED displays improve process visibility. These panels are made of sturdy and lightweight die-cast powder coated aluminum shells, designed to operate in the temperature range of -10 ° C to+60 ° C/0 ° C to+50 ° C. The front shell with IP66/IP65 protection level allows it to withstand damp, dusty, and harsh environments. The latest technology related to panels For data, comparison, and data table generation, please visit the compact hardware selector. The PP865A operator panel has current isolation for 24 V DC feed, but there is no current isolation between the communication ports of RS232, RS422/485, and USB. PP865A only has current isolation for Ethernet connections. When the computer is connected to the panel, the internal 0V (GND) of the panel will be connected to the protective grounding through the computer

The grounding current passing through the communication cable, controller backplane, and inside the operation panel may cause errors. Use external units to improve communication and achieve current isolation. Many USB devices can connect shielding and protective grounding together. Here, when inserting a USB memory stick, keyboard, or similar device, the 0V (GND) of the panel is connected to the protective grounding.
