Detailed Description AST3302-B1-D24 (alias PFXST3302BAD) belongs to Pro-face ST3000 basic HMI series, designed for cabinet door embedded installation. It adopts 5.7-inch STN blue monochrome LCD, QVGA 320×240 resolution, 8 grayscale levels, CCFL backlight with 8-level touch brightness adjustment. Power supply DC24V (19.2~28.8V), max power consumption 18W, front panel IP65 dust and splash protection, rear IP20. Built-in flash memory stores HMI application project, battery-backed RTC retains recipe parameters, alarm logs and clock data after power failure.

This HMI integrates MPI interface specially for Siemens S7-300/400, RS232 serial port and USB host port for program upload/download. It supports Siemens MPI, and multiple protocols for Mitsubishi, Omron and other PLC brands. Programming software is GP-Pro EX. It supports real-time data monitoring, parameter input, alarm log recording, recipe management, multi-language switching and operation audit function. 4-wire resistive touch supports glove operation, stable for dusty and vibrating workshop environments.

Hardware adopts compact industrial housing, operating temperature range 0~50℃. Front LED indicators show power and communication status for fast on-site troubleshooting. Built-in watchdog circuit prevents system crash caused by industrial electromagnetic interference.

AST3302-B1-D24 is discontinued legacy Pro-face HMI spare part. Many old automation machines still run with this ST3000 MPI panel. When the original unit fails, replacing it with identical AST3302-B1-D24 can reuse existing cabinet cutout, field wiring and original GP-Pro EX project without redevelopment. Operators directly use familiar touch operation screens with no extra training. This replacement greatly reduces renovation cost and shortens equipment downtime, avoiding expensive full HMI system upgrade.

Before shipment, every AST3302-B1-D24 undergoes comprehensive functional inspection including power-on boot test, touch calibration, display quality inspection, MPI & RS232 communication verification, USB port test and backup battery health check. All products come with 12-month warranty. Our automation technical team provides remote support for project backup, wiring guidance, communication parameter setup and fault diagnosis. Fast global shipping is available for urgent maintenance orders.

For automation maintenance engineers and system integrators, AST3302-B1-D24 is reliable spare touch HMI for legacy Pro-face ST3000 control systems. It maintains stable on-site machine monitoring and manual operation functions, extends service life of automation assets and prevents costly reconstruction of human-machine interface.
