Turck TX400 Series Adds Power and Flexibility to HMI/PLCs

Turck has introduced the TX400 series, a new generation of HMI/PLC devices that combine touchscreen visualization and machine control in one platform. Available in four display sizes from 5 inches to 15 inches, the range adds a quad-core processor, doubled memory, and support for CodeSys V3 programming. With Ethernet, serial, CAN, and USB connectivity, the TX400 series is aimed at builders needing scalable, cost-effective industrial control solutions.

The new TX400 is an improved series based on the earlier TX207 platform, adding a quad-core processor across all models, doubling available RAM, and expanding the range of screen sizes. The result is a more capable HMI/PLC option that still fits applications where cost, form factor, and straightforward integration are key considerations.

Core Hardware and System Capabilities

The TX400 series uses a 64-bit quad-core processor running at 1.6 GHz, 2GB of RAM, and 4GB of flash memory. Compared to the TX207, the increase in memory and processing capability allows the system to handle more complex control logic and visualization tasks without slowing down under load.

The devices support CodeSys V3 for programming, as well as IEC 61131-3 languages, making them compatible with standard PLC development environments. Connectivity is handled via Ethernet, with integrated serial interfaces (RS232/RS485/RS422) and CAN, enabling the units to interface with a wide range of industrial controllers and field devices.

Model Breakdown and Key Differences

The TX400 HMI series is available in four display sizes, giving machine builders options based on space requirements and interface complexity. The 5-inch TX405 features an 800 × 480 resolution and the most compact footprint in the lineup, making it a strong fit for tight control panels, embedded systems, or distributed machine nodes where low power draw and minimal panel space are priorities. Moving up, the 7-inch TX407 increases resolution to 1024 × 600, offering a practical middle ground between screen visibility and enclosure size. That balance makes it well-suited for general-purpose operator stations and standalone machine interfaces.

For applications that require more data on screen at once, the 10-inch TX410 delivers a 1280 × 800 display designed for more advanced interfaces, including multi-variable monitoring and systems that combine HMI and PLC functions on a single screen. At the top of the range, the 15-inch TX415 provides a full HD 1920 × 1080 resolution and the largest viewing area in the family. Its higher information density supports dashboard-style control layouts, SCADA visualization, and diagnostic screens that require operators to see more detail at a glance. Across all of the TX400 models, the HMI is built around a 64-bit quad-core 1.6 GHz processor, 2GB of RAM, and 4GB of flash memory, along with integrated Ethernet, USB, serial (RS232/RS485/RS422), and CAN interfaces. Keeping these core specs the same simplifies scaling designs across different machine sizes or applications without requiring changes to the control architecture or software.

Industrial Design and Integration

The TX400 units use a plastic housing similar to the TX207, keeping costs down while maintaining durability in industrial environments. They are rated for operation between -20°C and 55°C and feature IP66 front protection, making them suitable for typical factory floor conditions.

Power requirements are standardized at 24 VDC, and installation is handled through standard panel cutouts. The inclusion of USB, Ethernet, and multiple serial ports enables straightforward integration without requiring additional interface modules.

Turck’s TX400 series brings expanded display options and consistent hardware across multiple form factors into a single HMI/PLC platform. These HMIs will feature a quad-core processor, double the memory, and support standard industrial communication and programming environments. The series provides a practical, cost-effective option for applications that need both control and visualization without added system complexity.
