E4809-032-458

The Okuma E4809-032-458 CPU board is a robust member of the E4809 CNC Boards series designed and manufactured by Okuma for precision industrial automation and CNC process control. This board incorporates an Intel 80486 Processor or equivalent, delivering ample computational power for complex machining tasks. Its primary function is to serve as the central processing unit in CNC control systems, coordinating signal exchange, data retention, and logical operations. Key specifications include dual 50-pin Centronics-type connector ports for backplane interface and a certified operating temperature range of 0°C to 50°C, ensuring stable performance under varying shop-floor conditions.

In terms of technical construction, the E4809-032-458 features a passive and forced air cooling arrangement, utilizing ambient or fan-driven airflow to maintain optimal component temperatures. The board’s logic is implemented through a strategic mix of TTL and CMOS DIP ICs, providing both high-speed switching and low power consumption. Signal integrity is preserved by gold-plated communication pins on edge connectors, which facilitate serial and parallel data transfer depending on slot population. Onboard protection and noise suppression are achieved through a combination of disc ceramic and electrolytic capacitors, which regulate voltage, filter transients, and stabilize logic circuits. Mounting is straightforward as a slot-in fixed board, supported by a circular white battery module that retains volatile data during power interruptions.

Additional features include clearly labeled diagnostic access points and component layouts to expedite servicing and minimize downtime in high-demand industrial settings. The inclusion of multiple black rectangular relay driver ICs enables direct actuation of CNC relays without external modules, enhancing efficiency and reducing system complexity. Weighing approximately 1-2 lbs, the E4809-032-458 maintains a balance between compactness and durability, compatible with standard Okuma equipment chassis. Although no specific certification standards beyond industry norms are listed, its design adheres to rigorous performance criteria for reliability in industrial automation. Utilizing this CPU board in manufacturing applications translates to improved uptime, simplified maintenance, and precise control of machining processes, delivering tangible benefits to modern production environments.
