Functional Characteristics

• High-Speed Control: The module features an FPGA hardware accelerator in its kernel, enabling analog closed-loop refresh rates as fast as 100 µs. This eliminates the issue of “control waiting for communication” and allows for simultaneous completion of weighing and batching, tension regulation, and electronic cam operations within the same code.
• Versatile I/O Capabilities: The module provides a comprehensive set of I/O channels, including DI, DO, AI, and AO, with flexible configuration options. The AI channels support both current and voltage inputs, while the AO channels offer 12-bit PWM for heating power regulation.
• Robust Communication: With dual RS485 ports and a single Ethernet port, the module supports multiple communication protocols, including Modbus RTU, TCP, and Profinet. It can transmit 32 registers to SCADA within 1 ms and write back setpoints in the next cycle without the need for additional gateways.
• High Reliability: Designed for 24/7 operation in harsh industrial environments, the module features a wide operating temperature range, high vibration resistance (1g), and a protection class of IP20 (front panel). It requires no fan or air conditioning, reducing maintenance needs.
• User-Friendly Interface: The module is equipped with three LEDs on the front panel to display real-time RUN, ERROR, and I/O status, enabling quick fault diagnosis and reducing average diagnostic time from 30 minutes to 3 minutes.
• Compact Design: The compact size of the module (115 × 45 × 25 mm) allows it to be installed in space-constrained environments, such as directly on the frame of an extruder, without the need for expanding the electrical distribution room.

Application Scenarios

• Extruders: In blow molding machines, the module uses 4 AI channels to read pressure and 4 AO channels to control heaters, while DO channels drive servo cutters. It completes thickness closed-loop control within a 100 µs cycle, achieving a membrane thickness tolerance of ≤±2 µm.
• Reactors: In reactor applications, AI channels are connected to temperature and pressure sensors, while DO channels control feed valves. The Ethernet port sends actual values to an AC 800M controller for safety interlocking, with a communication delay of less than 1 ms.
• Robotic Seventh Axis: DI channels read encoder zero positions, AO channels output ±10 V speed curves, and PWM occupancy ratio is adjustable to 0.1%. This setup ensures a repeatable positioning accuracy of ±0.02 mm.
