E4809-436-072-C
The Okuma E4809-436-072-C circuit board is a core component of the E4809 CNC Boards series, designed to deliver reliable, precision control in high-demand industrial environments. Manufactured by Okuma, this board features a face mount standard Okuma interface for direct replacement in CNC control assemblies and seamless compatibility with Okuma Fanuc controllers. It is constructed from high strength aluminum alloy to ensure mechanical rigidity and thermal dissipation across its compact form factor. Key capabilities include high-speed data buffering via on-board SRAM and DRAM memory ICs, real-time clock synchronization through a metal-can oscillator, and robust signal routing with integrated 74HC373 octal latch and 74HC244 buffer/driver logic ICs. With an approximate power consumption of 75 W, it balances performance with efficient energy use, making it ideal for continuous operation.
Detailed technical specifications underline its suitability for precision automation tasks. The board dimensions of 120 x 80 x 50 mm allow installation in space-constrained control cabinets, while the approximate weight of 3.5 kg provides a stable mounting profile. Environmental resilience is achieved with an IP54 protection rating and an operating temperature range from -10°C to +60°C, ensuring performance across typical shop floor conditions. The standard adjustment tolerance of ±0.05 mm guarantees accurate mechanical alignment during installation. Multiple connector types—large edge connectors, blue terminal blocks, and white peripheral connectors—facilitate comprehensive I/O, power, and sensor linkages. This board uses a direct replacement mounting type and supports factory-standard adjustment procedures, reducing downtime during maintenance.
Operational features focus on sustaining high throughput and signal integrity in dynamic CNC systems. Noise suppression is provided by strategically placed electrolytic and ceramic capacitors, while the logic ICs maintain consistent latch and buffering functions for rapid command execution. The operating temperature control is enhanced by the aluminum alloy chassis, which acts as a heatsink under extended load conditions. Real-time data processing is supported by ample memory ICs, reducing latency in motion control loops. The metal-can oscillator delivers a stable clock frequency that synchronizes machine axes and peripheral functions, ensuring cohesive machine operation even under variable load scenarios.
System integration is streamlined by the board’s Connection Interface compatibility with Okuma Fanuc controllers, enabling plug-and-play interoperability within existing control architectures. With its comprehensive Connectors layout and proven installation track record, it serves applications ranging from high-precision milling and turning centers to automated grinding and robotics. The robust Environmental Rating and rugged mechanical construction make it an optimal choice for industrial automation, where reliability and uptime are paramount. Engineers can leverage the E4809-436-072-C for rapid system upgrades, retrofit projects, and new machine builds that demand precise motion coordination and data handling.
