HITACHI XCU232H High Speed Counter Module

Technical Specifications

• Provides 2-channel independent high-speed counter inputs, supporting single-phase or two-phase pulses
• Equipped with a 32-bit counter, supporting an ultra-wide counting range of up to ±2,147,483,647       
• Supports high-frequency pulse signal inputs up to 50 kHz or 100 kHz
• Compatible with standard industrial 5V DC, 12V DC, or 24V DC pulse signal inputs

The XCU232H is a function component within the Hitachi PLC system. Operating outside the main CPU scan cycle, the module utilizes an independent microprocessor to receive high-frequency industrial pulse signals. It provides 2 independent counting channels and integrates a 32-bit bidirectional Up/Down counter, supporting pulse input modes such as single-phase input, dual-phase quadrature input, and pulse-plus-direction input. In the dual-phase quadrature mode, the module supports 1x, 2x, and 4x frequency multiplication to identify the rotation direction of a mechanical axis via a rotary encoder for position feedback.

Applications and Features

Lifecycle and Market Status

The Hitachi XCU232H has been deployed in a wide range of industrial automation systems based on the H-Series PLC platform. Although the module has reached the mature stage of its product lifecycle and is no longer in standard production, it remains available for system maintenance and replacement. The module is used to support the continued operation and expansion of existing H-Series control systems across various industrial applications.

Technical FAQ

Q: What pulse input modes does XCU232H support?
A: It supports single-phase input, dual-phase (A/B phase) quadrature input, and pulse-plus-direction input.

Q: How does XCU232H identify the rotation direction of a mechanical axis?
