Delta TP04G-AS2 Keypad HMI – 4-Line LCD, RS-232/485, IP66, Keypad Control

The Delta TP04G-AS2 is a compact and reliable keypad-based HMI. It is designed for small control panels and OEM use.

It features a 4-line monochrome STN LCD display with a resolution of 192×64 pixels. While it is not a touchscreen, it allows fast control through function keys and a numeric keypad.

This model supports both RS-232 and RS-485 communication. As a result, it connects easily with Delta PLCs and automation equipment.

Although the design is compact, the panel includes essential features such as an alarm LED, adjustable contrast, and a programmable backlight timeout. Moreover, the unit is protected by an IP66-rated front panel, making it suitable for light industrial environments.

Because the TP04G-AS2 supports TPEditor and DIAScreen, it simplifies programming and deployment. Furthermore, it includes a built-in real-time clock (RTC) with battery backup.

Due to its versatile keypad, simple design, and solid communication support, it is ideal for applications where screen size and budget are limited.
