C340FG Industrial HMI Panel

Description

The C340FG functions as a touchscreen HMI panel, serving as the central interface between operators and industrial control systems such as PLCs, DCS, or SCADA systems. It features a 4.3-inch color TFT display with a resolution of 480×272 pixels, equipped with a resistive touchscreen that supports both finger and stylus input, ensuring reliable operation even with gloves—essential for environments where hygiene or safety protocols require hand protection. What sets it apart is its high-brightness display (500 cd/m²) with anti-glare coating, ensuring visibility in direct sunlight or brightly lit factory floors, a common issue with standard HMI panels. The panel supports multiple communication protocols, including Ethernet/IP, Modbus RTU, and Profibus, enabling seamless integration with a wide range of industrial controllers. It includes 128MB of flash memory for storing graphics, recipes, and log data, along with 64MB of RAM for smooth operation of complex HMI applications.

C340FG

Main features and advantages:

Choosing the C340FGoffers several significant benefits for industrial automation systems. Its compact size (121mm x 82mm x 32mm) makes it ideal for installation in space-constrained control panels, such as on small machinery or retrofitted equipment where larger HMIs cannot fit. The high-brightness, anti-glare display ensures operators can monitor processes accurately in any lighting condition, reducing errors caused by poor visibility. Engineers will appreciate the flexible communication options, which eliminate the need for protocol converters when integrating with diverse controllers, simplifying system architecture and reducing costs. The IP65 front panel protection allows for installation in washdown environments, such as food processing or pharmaceutical facilities, where regular cleaning with water or chemicals is required. Most importantly, the C340FG’s rugged design ensures reliable operation in vibrating environments—such as near pumps or motors—minimizing downtime due to display or touchscreen failures.

Application areas:

The C340FG excels in a variety of industrial applications where compact, durable HMIs are essential. In packaging machinery, it allows operators to adjust filling parameters, monitor conveyor speeds, and view alarm histories, with the resistive touchscreen enabling quick changes even while wearing gloves. In water and wastewater treatment plants, it displays real-time data from flow meters and pH sensors, allowing operators to adjust valve positions or pump speeds to maintain water quality, with the high-brightness display ensuring readability in outdoor pump stations. The panel also performs reliably in automotive assembly lines, where it controls robotic cell operations, displaying error codes and maintenance alerts to help technicians resolve issues promptly. In each scenario, the C340FG provides the intuitive interface and durability needed to keep operations running smoothly.
