by Okuma
The Okuma E0777-702-003 CNC board is a robust module in the E4809 CNC Boards series designed to deliver stable program storage and control support in industrial automation systems. Featuring 1 Mbit bubble memory for non-volatile data retention and an extended operating range of -20°C to +70°C, this plug-in PCB module ensures uninterrupted performance even in harsh manufacturing environments. Its primary function is to store critical machining programs and parameters while interfacing seamlessly with Okuma CNC machines to manage toolpaths and process data efficiently.
This board leverages bubble memory technology to minimize data corruption risks and offers a memory capacity of 1 Mbit. It operates on a 5 V DC supply and achieves a data transfer rate of up to 2 MB/s through a custom parallel system interface tailored for CNC integration. The module’s dimensions of 89 × 55 × 10 mm and weight of 150 g enable compact installation in control cabinets, while the plug-in PCB mounting style simplifies replacement and reduces downtime. The use of a custom parallel interface ensures low-latency communication, setting it apart from standard flash-based memory solutions.
Beyond core memory functions, the E0777-702-003 provides broad CNC compatibility and supports networked control via an integrated Ethernet communication interface. Rated for 5% to 95% RH non-condensing humidity and protected by surge-tolerant circuitry, this board withstands electrical noise and environmental stress. Its plug-in design enhances serviceability, and its light weight aids vibration resistance. Certified for industrial use, the module’s reliable performance boosts system uptime, reduces maintenance costs, and streamlines program updates, making it an ideal choice for precision machining and high-demand production lines.
