Pro-face GP2301H-LG41-24V Handheld HMI Touch Screen: Technical Overview and Specifications
Pro-face GP2301H-LG41-24V Handheld HMI Touch Screen
The Pro-face GP2301H-LG41-24V is a rugged, handheld operator interface designed for portable industrial control. It features a 5.7-inch monochrome amber/red LCD with a resistive touch screen. Running on a DC 24V input, this model provides localized machine control. Crucially, it incorporates dedicated hardware safety switches, including an emergency stop. This integration helps minimize cabling complexity while maintaining safety integrity on the factory floor. Download the official datasheet from the Pro-face Manual Archive.
Hardware-Level Safety and Interface Integration
The primary advantage of the GP2301H-LG41-24V is the physical integration of safety devices into the operator interface housing. It includes a 3-position enable switch (deadman switch) and an emergency stop button. These switches connect via dedicated pins in the main cable. This routing ensures safety signals bypass the HMI internal software. The hardware signals communicate directly with safety relays or PLCs, ensuring fail-safe operation during manual teaching tasks.
The unit relies on a 5.7-inch monochrome display based on mature LCD core technology. The amber and red backlighting is optimized for high-contrast viewing under variable factory lighting conditions. An emergency stop button on a handheld HMI functions like a mechanical handbrake on a vehicle. It provides a direct physical interrupt that functions independently of the operating system or software runtime.
Engineers seeking to replace legacy units can compare these parameters with current smart factory HMI touch and display specifications. Portable control requirements often differ from stationary terminals. The physical design of these industrial HMIs prioritizes drop resistance and tactile feedback. This is essential when operators must maintain visual focus on the machinery rather than the screen.
Industrial Applications
- Robotic Cell Calibration: The enabling switch permits safe entry into the robot working envelope during path programming.
- Conveyor Troubleshooting: Operators can walk along production lines while diagnosing sensor faults via the serial communication connection.
- Material Handling Override: Serves as a manual override station for automated guided vehicles (AGVs) or overhead cranes during maintenance cycles.
Best-Fit Conclusion: The GP2301H-LG41-24V is optimized for machinery setups requiring simultaneous handheld visualization and hardware-hardwired emergency stop capabilities.

Engineer FAQ
Q1: How are the safety switches on the GP2301H-LG41-24V wired to the control system?
The safety switches use dry contacts that terminate directly on specific pins of the interface connector. They do not interface with the serial communication bus. You must wire them in series with your system’s master safety relay circuit.
Q2: What communication protocols does this HMI support?
It supports standard point-to-point and multi-drop serial protocols for major PLC brands. These are configured through the GP-Pro/PB III development software. The physical connection supports RS-232C and RS-422 modes.
Q3: Is the CCFL backlight replaceable on this model?
The backlight is a cold cathode fluorescent lamp. It is rated for approximately 50,000 hours of continuous operation under normal temperatures. When the backlight dims or fails, the module must be serviced or replaced using compatible parts.
The Pro-face GP2301H-LG41-24V integrates graphic display capability with mechanical safety switches in a portable housing. This combination provides a practical option for machine tuning and robotic teach pendant integration where functional safety and mobility are required.
