Pro-face PL6921-T41 15-Inch Industrial HMI Touch Panel

Description

Key Technical Specifications

The PL6921-T41 belongs to Pro-face’s PL6000 family of industrial panel PCs. The T41 configuration denotes the touchscreen-oriented version, while 2780054-03 should be retained as the procurement identifier for the specific unit.

Product Introduction

The Pro-face PL6921-T41 (2780054-03) is a 15-inch industrial operator interface from the PL6000 Series. Its 4:3 TFT display and resistive touchscreen are suited to applications where operators need direct access to machine status, process values, alarms, recipes, and control commands.

The PL6000 platform is more than a conventional standalone HMI display. It is designed as an industrial panel-computing platform, allowing the operator interface and computer functionality to be integrated into the control cabinet.

For a replacement installation, the important point is to distinguish the PL6921-T41 front-panel configuration from the complete PL6000 computer configuration. Processor, memory, storage, operating system, and installed application software can vary by configuration.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — 5–10 Minutes

⚠️ Safety First: Shut down the controlled machine and isolate the panel PC from its power source before removing the unit. Follow the plant’s lockout/tagout procedure.

Before Removal

1. Place the machine in a safe state.
2. Disconnect power to the PL6921-T41.
3. Verify that the unit is de-energized.
4. Photograph the front and rear of the existing panel.
5. Record the complete model and part number.
6. Photograph all communication and power connections.
7. Record the installed operating system and HMI application version if applicable.
8. Back up the application before hardware replacement whenever possible.

Stage 2: Removing the Existing Unit

1. Label all cables before disconnecting them.
2. Disconnect Ethernet and serial communication cables.
3. Disconnect USB and peripheral connections.
4. Disconnect the power supply.
5. Release the panel mounting hardware.
6. Support the unit while removing the final fasteners.
7. Carefully remove the panel PC.
8. Inspect the panel opening, mounting surface, and gasket.

⚠️ Do not assume that another 15-inch Pro-face HMI has the same panel cutout. Screen size alone is not sufficient for mechanical compatibility.

Stage 3: Installing PL6921-T41

1. Verify .
2. Compare the replacement unit with the original before installation.
3. Confirm the display and touchscreen are free of damage.
4. Verify the panel cutout.
5. Position the unit in the panel.
6. Install and evenly tighten the mounting hardware.
7. Reconnect power.
8. Reconnect communication cables.
9. Reconnect USB and peripheral devices as required.
10. Verify that no cables are trapped or excessively stressed.

Stage 4: Power-On & Commissioning

1. Check power wiring and polarity.
2. Restore power.
3. Confirm normal startup.
4. Verify the display.
5. Test touchscreen response across the active display area.
6. Verify Ethernet/serial communication.
7. Start the installed HMI application.
8. Confirm PLC/controller data.
9. Test alarms and status indications.
10. Test representative operator commands.
11. Verify the system under normal operating conditions.

Frequently Asked Questions

Q1. What isace ?

The is a 15-inch touchscreen industrial panel computer/operator interface in the PL6000 Series.

Q2. What is part number 2780054-03?

2780054-03 is the part/registration identifier associated with the configuration. For purchasing a replacement, provide both identifiers rather than relying on the model alone.

Q3. What is the display resolution?

The uses a 1024 × 768-pixel 4:3 display.

Q4.the have a touchscreen?

Yes. The T41 configuration uses an analog resistive touchscreen, making it suitable for direct operator interaction in industrial environments.

Is a complete industrial PC?

The platform is an industrial panel-computing system rather than simply a passive HMI display. However, the exact CPU, memory, storage, and software configuration should be verified from the individual unit’s nameplate and system information.

Q6. What should I check before ordering 2780054-03?

Verify:

• Model:
• Part number: 2780054-03
• 15-inch display
• 1024 × 768 resolution
• Resistive touchscreen
• Physical panel cutout
• Power requirements
• CPU/RAM/storage configuration
• Operating system
• HMI application
• Communication interfaces

For a legacy replacement, request photographs of the front nameplate and rear label from the supplier. This is especially important because configurations can differ internally even when the front-panel dimensions appear similar.
