Delta TP04P Series Keypad HMI – With Built-in PLC & I/O Options

The Delta TP04P Keypad HMI is a compact HMI solution that also integrates PLC functionality and I/O. Because of this 2-in-1 design, it saves space and reduces wiring needs in control panels.

Each model features a 4.1” monochrome LCD, a numeric keypad, and function keys for quick navigation. While all models share the same display and layout, the I/O configuration varies to meet different application needs.

In addition to its keypad input, the TP04P series supports RS-485 and USB communication, which makes programming and data transfer easy. You can use WPLSoft or TPEditor to create logic and HMI screens in one project.

Moreover, these units include alarm LED indication, adjustable contrast, and backlight timeout features. As a result, they are ideal for OEMs who require basic automation with both digital and analog signals.

Because the front panel is IP66-rated and the device is CE/UL certified, it can be installed in industrial environments with confidence.
