The Delta TP02G-AS1 is a compact text-panel HMI from the TP Series, built around a 2.8-inch monochrome STN-LCD with 160 × 32 pixel resolution and a 16-key tactile keypad. Designed for simple machine control applications — conveyor systems, packaging machines, pump control panels, and HVAC equipment — it provides essential operator interface functions in a panel-mount format with an IP65/NEMA 4-rated front face that withstands washdown and dusty industrial environments.

Why dual simultaneous communication ports?

The TP02G-AS1 is equipped with two independent serial ports: COM1 (RS-232) and COM2 (RS-485), each configurable from 4,800 to 115,200 bps with selectable data bits, stop bits, and parity. Both ports can communicate simultaneously using different protocols — for example, RS-232 to a local PLC and RS-485 to a remote SCADA or building management network — eliminating the need for an external protocol converter. Dedicated yellow (RS-232) and green (RS-485) LEDs on the front panel provide visual confirmation of communication activity on each port.

How does the program copy card simplify field deployment?

The extension slot accepts a Delta program copy card that stores the complete HMI configuration — screens, function key assignments, communication settings, and passwords. An installer sets up one TP02G-AS1 on the bench, copies the configuration to the card, then inserts the card into each additional panel on the production floor to replicate the setup in seconds. No laptop, software, or cable is required at the machine during commissioning. The same card can also back up a field unit's configuration before maintenance or replacement.

What programming and security features are included?

Sixteen tactile function keys (F0 through F9 plus ESC, ENTER, and four directional arrows) provide direct machine control — start/stop, jog, mode select, parameter entry — without a touch screen. Password protection secures configuration parameters from unauthorized changes. The alarm LED on the front panel flashes on power-up, blinks rapidly on system errors, and is user-programmable for application-specific alerts. Multi-language display support includes ASCII European character sets, Traditional Chinese (BIG5), and Simplified Chinese (GB2324-80).
