Proface GP37W2-BG41-24V Industrial HMI

The Proface GP37W2-BG41-24V is a robust and reliable monochrome industrial human-machine interface (HMI) designed for demanding automation environments where clarity, durability, and straightforward functionality are paramount. As part of the proven GP3000 series, this HMI model features a compact design with a high-contrast blue-and-white LCD display, making it ideal for applications requiring essential visualization and control without the complexity of full-color interfaces. Its rugged construction ensures consistent performance in harsh industrial settings, serving as a critical communication link between operators and machinery in sectors such as manufacturing, process control, and packaging.

Key Features and Technical Specifications

High-Contrast Monochrome Display

The GP37W2-BG41-24V is equipped with a monochrome (blue-and-white) LCD that delivers excellent readability in various lighting conditions

. The display offers a resolution of 320 × 240 pixels and supports adjustable contrast with eight user-configurable levels. The CCFL backlight has a rated lifespan of over 25,000 hours, ensuring long-term reliability and reduced maintenance needs

. This combination provides a clear and sharp interface for displaying operational data, alarm messages, and control elements.

Durable Industrial Design

Built to withstand challenging industrial environments, this HMI boasts a front-panel protection rating of IP65 (as per JEM1030) when properly installed, making it dust-tight and resistant to water jets

. Its robust housing ensures reliable operation within a temperature range of 0°C to 50°C and provides strong resistance to vibration and interference. The unit consumes relatively low power (typically 10W, maximum 20W) and is designed for natural air cooling, contributing to its energy efficiency and suitability for enclosed panels

.

Efficient Memory and Processing

With 1MB of FLASH EPROM for screen data storage (capable of holding approximately 320 screens) and 96KB of SRAM for data backup

, the GP37W2-BG41-24V effectively handles essential HMI tasks. The backup memory is supported by a lithium battery, ensuring data retention during power interruptions. The resistive analog touch panel supports 1 or 2-point touch with a 16 × 12 key matrix per screen, enabling responsive and accurate operator inputs

.

Multilingual Support and Connectivity

This HMI supports multiple languages, including ASCII (Code page 850 with European characters), Simplified Chinese (GB2312-80), Japanese (JIS standards), Korean (KSC5601-1992), and Traditional Chinese (Big 5)

. This capability allows for deployment in diverse global manufacturing environments. The unit offers connectivity options for integration with PLCs and other industrial control devices, supporting open communication protocols that enable connectivity with a wide range of automation equipment

.

User-Friendly Programming

Programming the GP37W2-BG41-24V is facilitated by Proface's GP-PRO/PB III software (version 6.0 or later required)

, which provides an intuitive Windows-based environment for screen design and configuration. The software supports features such as alarm history logging, display of multiple languages, and font scaling (1x, 2x, 4x, or 8x)

, allowing for the creation of clear and functional operator interfaces tailored to specific application needs.
