The Hitachi CPU4 (CP76472PZ) is a highly reliable industrial control printed circuit board (PCB) module engineered specifically for Hitachi elevator control systems. As the main processing unit, this board is essential for coordinating, processing, and monitoring complex elevator operations to ensure safe and efficient passenger transit. It features a comprehensive array of diagnostic LED indicators that allow technicians to perform real-time monitoring of the CPU run state, online status, communication lines (SD/RD), and various critical signal inputs (SN, CT, TN, TL). For streamlined configuration and routine maintenance, the board includes integrated DIP switches (DATA, DSW1, DSW2), a dedicated hardware RESET button, and dual test connectors (T-CN1, T-CN2). Operational stability is guaranteed by the onboard CRZ CL2505-05 DC-DC converter, which regulates a +24V input to deliver a steady +5V (2000mA) output. Built with robust Japanese engineering standards, this OEM replacement PCB module is designed to seamlessly restore optimal functionality to your Hitachi elevator infrastructure.
