PFXGP4401WADW - Pro-face GP4000 7 inch wide analog HMI

Pro-face GP4000 7 inch wide analog HMI. Documented facts, inferred system position, and evidence boundary are recorded for maintenance review.

Documented product role

Rebuilt from individual evidence

System placement

Unknown: Evidence boundary

Pro-face identifies PFXGP4401WADW as a GP4000 Series HMI with a 7 inch wide DC analog configuration.

The product specification lists a 7.0 inch TFT color LCD, 800 x 480 WVGA resolution, and an analog resistive touch panel.

The product uses a 24 Vdc rated input and the manufacturer documents Ethernet, serial, USB, and SD interfaces.

PFXGP4401WADW sits at the operator panel layer between a person and connected machine-control equipment.

Unknown: The installed configuration, wiring, firmware, load, and site-specific compatibility are not established by the captured sources.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Displays configured HMI screens and accepts resistive-touch operator input.
System position: Sits at the operator panel layer between the operator and machine-control equipment.
Upstream / inputs: Receives 24 Vdc power, touch actions, and configured screen data.
Downstream / outputs: Presents WVGA status and controls and exchanges data through documented interfaces.
Limitations: Unknown: The installed configuration, wiring, firmware, load, and site-specific compatibility are not established by the captured sources.
