The QD62-H02 is a high-speed Mitsubishi counter module designed for industrial automation applications, featuring 2-channel 1Mpps differential input for precise counting of high-frequency signals. It directly connects to up to 4 expansion modules via the MELSEC system bus, supporting seamless integration with Mitsubishi PLC systems. Operating at 24V DC with a temperature range of 0-55°C, this module excels in environments like packaging machinery, semiconductor manufacturing, and motion control systems requiring rapid pulse processing. Its key advantages include noise-resistant differential input, compact design, and reliable synchronization with PLC logic. However, it lacks isolated inputs and requires compatible Mitsubishi base units, limiting flexibility in mixed-brand setups.
