Mitsubishi Electric FX3U-2HC High-Speed Counter Module

The Mitsubishi Electric FX3U-2HC High-Speed Counter PLC Module delivers precise high-speed counting and encoder-compatible pulse input processing for motion and positioning tasks in industrial automation. This two-channel module accepts 5–24 VDC inputs, supports up to 200 kHz counting speed (dependent on mode), and offers counting modes including up/down, phase difference, and pulse/direction, with photocoupler isolation to reduce noise and miscounts. It provides comparator outputs and is designed for DIN rail or panel mounting, making it suitable for expansion, retrofit, or replacement within Mitsubishi FX3U PLC systems. As part of the MELSEC-FX3U series, the FX3U-2HC integrates with FX3U-compatible hardware for scalable high-speed counting in encoder-based applications. Common applications include encoder-based positioning on packaging machines, indexing conveyors, labeling equipment, cutting machines, and other automated production lines requiring real-time pulse counting and precise measurement.
