The ABB CP620-WEB 1SAP520200R0001 is a 4.3-inch wide-format TFT color touchscreen with LED backlight, running 64k colors at 480 x 272 pixel resolution. It's built for panel-mount front-face install and carries an IP66 rating on the front per IEC 60529 — meaning it'll handle washdown and dust out here in the grease without blinking. Power is 24 V DC (18 to 30 V range) and it pulls 9.6 W, so it's light on the panel supply.
Connectivity and memory
Dual 100 Mbit Ethernet ports handle the plant-floor network, and there's a serial port configurable as RS232, RS422, or RS485 for legacy gear. A USB 2.0 host port lets you plug in a thumb drive for recipe transfers or logs. User data lands on 128 MB of flash disk, while the program runs on 256 MB of DDR RAM — enough for a moderate line but not a multi-machine cell. There's a hardware real-time clock with battery backup so time stamps survive power cycles.
