The Inovance H3U series is a third-generation high-performance compact PLC that integrates a powerful CPU with flexible I/O and advanced motion control capabilities. Designed to meet the demands of modern industrial automation, the H3U series offers exceptional processing speed, extensive communication options, and a robust programming environment, making it an ideal choice for a wide range of applications.

High-Performance Processing and Capacity

At its core, the H3U PLC is built for speed and efficiency. It delivers a basic instruction execution time of just 100 ns, ensuring rapid response times for time-critical applications. The controller supports a program capacity of up to 64,000 steps, providing ample space for complex control logic. Device memory is equally generous, with over 9,000 auxiliary relays, 9,552 data registers, and 32,768 file registers, enabling extensive data handling and storage without requiring battery backup.

Advanced Motion Control Capabilities

The H3U series excels in motion control applications. The standard model offers high-speed inputs (8 channels at 200 kHz) and outputs (5 channels at 200 kHz), supporting two-axis circular and point-to-point interpolated motion. The high-end motion model further extends these capabilities with high-speed differential outputs up to 500 kHz and advanced functions such as three-axis point-to-point interpolation, spiral curve motion, and a three-axis electronic cam, making it suitable for complex multi-axis coordination tasks.

Versatile I/O and Communication

Flexibility is a key strength of the H3U series. The combined CPU and power supply design supports a wide range of I/O configurations, including local digital I/O (up to 192 points) and analog I/O (up to 24 points). For larger systems, remote I/O expansion supports up to 7,936 digital and 1,488 analog points. Connectivity is robust, featuring multiple communication protocols including Ethernet (MODBUS-TCP), RS485 (MODBUS-RTU), CANopen, and CANlink. This allows the PLC to seamlessly integrate with various devices, HMIs, and higher-level networks for comprehensive automation solutions.

Intuitive Programming with AutoShop

Engineering is streamlined with AutoShop, Inovance's dedicated PC programming software. AutoShop provides a user-friendly graphical interface and supports multiple programming languages, including Ladder Diagram, Instruction List, and Sequential Function Chart (SFC). The software simplifies application development, commissioning, and maintenance, helping to reduce engineering time and costs. The H3U controller is also designed to operate reliably in high ambient temperatures of up to 45 °C.

Applications

With its combination of high performance, compact design, and advanced features, the Inovance H3U PLC is ideally suited for a variety of industrial automation applications, including:

• General machine control and factory automation
• Packaging machinery and material handling systems
• Multi-axis positioning and motion control tasks
• Textile, printing, and plastic machinery
• Renewable energy and power management systems
