Description
Product Introduction
The Pro-Face 3382701-03 (PL5910-T11) is a ruggedized 12.1-inch industrial panel computer engineered for demanding factory automation applications. Designed by Digital Electronics Corporation (Pro-Face), this unit integrates a high-contrast SVGA TFT display, an analog resistive touch screen overlay, and an industrial motherboard into a compact NEMA 4X / IP65 rated front-bezel housing. It acts as the primary operator control point for SCADA nodes, batch processing monitoring, and complex PLC system diagnostics.
Built to withstand severe industrial environments, the 3382701-03 hardware bypasses the flimsy construction of commercial-grade PCs in favor of a heavy-duty shielded chassis. It incorporates isolated RS-232C/RS-422 serial interfaces, expansion PCMCIA slots, and robust power noise filtering to maintain continuous polling across plant networks—even in high EMI environments near large variable frequency drives.

Application Scenarios & The “Trench” Experience
The “Trench” Reality
It’s 2:00 AM on a high-speed bottling line. A cooling fan failure inside a control enclosure causes an old PL5910 unit to thermal-lock, leaving the main screen completely unresponsive. The line stops, costing $800 every ten minutes. You don’t have the time or budget to cut out the panel door for a modern widescreen display, re-wire the communication cables, and translate legacy screen projects into new software. You need a drop-in 3382701-03 / PL5910-T11 replacement unit that mounts into the exact 12.1-inch cutout, accepts the original storage media, and gets the line running before the morning shift arrives.
Target Applications
- Food & Beverage Packaging Lines – Serving as a flush-mounted washdown operator interface for capper, filler, and palletizer machines.
- Automotive Stamping & Weld Cells – Displaying real-time part counts, fault alarms, and PLC I/O tables where high vibration is present.
- Plastics Extrusion Control – Regulating multi-zone heating barrels and tracking melt-pressure curves on a clear 12.1-inch display.
Field Replacement Case
A metal fabrication plant faced severe line stagnation when an aging panel computer suffered touchscreen matrix degradation, making key recipe buttons unpressable. Swapping in a bench-tested, refurbished Pro-Face 3382701-03 unit restored touch accuracy immediately. The technician simply moved the original system card over to the replacement chassis, eliminating the need for software re-licensing or re-programming.

Transparency SOP: Quality Assurance & Testing
We treat these legacy industrial computers with strict engineering rigor before placing them in inventory:
- Inbound Physical & Internal Inspection: Complete teardown to check for chassis warping, bezel gasket cracks, swollen power supply capacitors, and fan bearing wear.
- Power Rail Stability Check: Applying 120V/240V AC to verify that internal DC converter rails (+5V, +12V, +3.3V) maintain tight voltage regulation under load.
- Display & Touch Screen Matrix Calibration: Checking CCFL/LED backlight uniformity, display brightness, and performing a full multi-point touch accuracy test across the entire screen face.
- I/O Port & Expansion Stress Run: Testing COM1 and COM2 communication loops, PCMCIA card reader lines, and external keyboard/mouse connections.
- Burn-In & ESD Packaging: 24-hour continuous power burn-in, followed by anti-static cleaning and custom foam-padded, ESD vacuum sealing.
The Veteran’s Tech Trap Guide
⚠️ Trap 1: Verify Board Revision (3382701-03) vs. Base Model (PL5910-T11)
The number 3382701-03 typically refers to the specific internal motherboard / PCB assembly version inside the PL5910-T11 enclosure. Before swapping, check whether your original unit has custom daughtercards or expansion communication boards installed, and migrate those physical cards to the replacement unit.
❗ Trap 2: Mind the Internal Backup Battery
If your unit has been sitting in a spare parts closet for months, the internal SRAM backup battery might be depleted. If you turn on the unit and see a “System Error” or lose clock/retentive recipe data, replace the small 3V lithium coin cell battery located inside the side access hatch before loading your operational runtime.
⚠️ Trap 3: Inspect the Panel Mount Gasket
Never install a replacement panel PC using an old, compressed, or oil-soaked rubber gasket. A loose seal allows cutting fluids and washdown water to enter the cabinet, where moisture will seep into the bottom edge of the display inverter, causing a short circuit.
Frequently Asked Questions
Q: Is the Pro-Face -T11 / 3382701-03 still manufactured by Digital/Pro-Face?
No. The PL5900 series is discontinued by the OEM. We source, test, and stock pre-owned and new-surplus units so you can replace failed hardware without executing an expensive panel redesign or software migration.
Q: Can I transfer my operational project directly to this replacement unit?
Yes. If your original system card, PCMCIA memory card, or hard drive is undamaged, you can insert it directly into the replacement 3382701-03 chassis. The unit will boot your existing operating system and project files automatically.
Q: What operating systems are typically supportthe ?
Depending on the installed system memory and storage media, the platform natively supports legacy industrial OS environments including MS-DOS, Windows 95/98, Windows NT4.0, and Windows 2000/XP Embedded.
Q: Can I hot-swap this panel computer while main cabinet power is on?
No. To be honest, attempting to unbolt or un-wire this unit while 120V/240V AC power is live creates an electrical arc hazard and can ruin internal power supply fuses. Always de-energize the main cabinet disconnect before servicing.
Q: What warranty covers your refurbished Pro-Face panel computers?
Every pre-tested 3383 / unit is backed by our full 12-month direct replacement warranty from our stocked inventory.
