E4809-770-139
by Okuma
The Okuma E4809-770-139 MPBDN-P card is a high-performance interface from Okuma's E4809 CNC Boards series. It features a Renesas H8S/2398 MCU and Xilinx CPLD/FPGA integration to deliver real-time axis control and high-speed signal processing. With a wide 100-240 VAC power supply range and 50 W power consumption, it is engineered for robust performance in industrial automation. Incorporating bulk capacitors for voltage stabilization and transient voltage suppression for overvoltage protection, this board ensures reliable, uninterrupted operation in demanding environments.
In terms of detailed technical specifications, the E4809-770-139 measures 120 x 80 x 60 mm and mounts securely via four metal reinforced holes for chassis installation. Power is supplied through a large 12-pin header connector, facilitating stable input distribution. Onboard connectivity includes an IDC ribbon at XB1 for I/O communication, a high-density XB3 connector for axis control and encoder feedback, plus pin headers at XB5–XB7 and black connectors at XS5–XS7 for additional sensor and I/O integration. A 10-position DIP switch block (SW1) allows manual configuration of axis ID, baud rate, and operating modes.
Designed for compatibility and durability, the E4809-770-139 is rated to IP67 protection class, safeguarding against dust ingress and temporary immersion. Its efficient design incorporates noise-filtering circuits and analog/digital ICs for clean signal conditioning from encoders and sensors. The robust chassis mounting and industrial-grade components guarantee longevity under continuous operation. By integrating high-speed motion control processing, stable power management, and modular connectivity, this MPBDN-P card enhances system efficiency and reliability in complex CNC and automation applications.
