E4809-770-130 by Okuma

The Okuma E4809-770-130 control board from the E4809 CNC Boards series, manufactured by Okuma, is a robust circuit board designed for demanding industrial automation environments. It accepts an Input Voltage: 100-240 VAC and provides a stabilized Output Voltage: 24 VDC at Output Current: 3.5 A, ensuring ample power delivery to downstream components. Sized at Dimensions: 200 mm x 100 mm and optimized for Mounting: Panel/Chassis mount, this board integrates seamlessly into standard CNC rack enclosures. Connectivity is provided through a dual-mode Connectors: Edge connector and screw terminal block, with gold-plated contacts that guarantee low-resistance, reliable signal transmission. The board’s compact footprint and structured layout simplify installation and maintenance in complex machine control systems.

Equipped with high-performance onboard voltage regulation circuits, the E4809-770-130 manages both Regulated Voltage: 5V or 3.3V rails for the embedded logic and driver subsystems. A standard Interface: RS-232 serial interface enables diagnostics and seamless communication with auxiliary modules and operator consoles. The board routes signals across Channels: XB1 to XB13, providing dedicated lines for sensors, actuators, and interlock circuits. System firmware resides in dual non-volatile Memory: EEPROM/EPROM arrays, preserving CNC configuration and logic even during power interruptions. Passive components—precision resistors, ceramic and electrolytic capacitors—are distributed for advanced signal conditioning, voltage filtering, and noise suppression. Gold-plated edge contacts and robust screw-terminal blocks enhance connection integrity under continuous vibration and thermal cycling.

Reliability is further reinforced by an Operating Temperature: 0°C to 50°C rating and conformal coating on critical components to resist dust and moisture. Reinforced mounting holes at each corner ensure secure fastening and proper grounding within numeric rack enclosures, while the board’s gold-plated edge contacts deliver corrosion-resistant connectivity over extended lifecycles. Designed for panel or chassis applications, the E4809-770-130 integrates readily with Okuma’s modular control architecture, facilitating fast swap-out and minimal downtime. This versatile board is ideal for precision milling, turning centers, and multi-axis automation cells where dependable signal management and streamlined integration are essential for high-throughput, high-precision CNC operations.
