Product Description:

The E4809-045-106-D OPUS 5000II CRP II-C Board is a PC board that has been specifically designed for industrial automation. Okuma's circuit is designed to ensure that CNC systems run precisely by integrating memory, processing, and control elements. The board's built-in connectors make it easy to connect to CNC controllers and other devices.

In order to store firmware and process buffer memory, the E4809-045-106-D PC board makes use of ICs labeled OKUMA (OCL512, OCL513, OCL512 GRC). The HD74LS166AP shift registers convert data from serial to parallel, which allows for efficient feedback processing and command execution. In order to facilitate CNC operations in real time, the 41264 DRAM memory chip offers temporary data storage. The control timing and synchronization are supported by many 74LS series logic ICs that act as data latches, buffers, and bus controllers. Direct connection to the CNC controller backplane is possible with the help of the gold-plated edge connector. Motors, sensors, or other peripherals can be connected externally with the high-density DB-style connector. Electrolytic capacitors and filtering components minimize voltage fluctuations and noise, ensuring power control. Oscillators and timing crystals on the board ensure precise timing signals for logic operations.

Stable performance is guaranteed by the E4809-045-106-D PC board's high-quality construction. The board functions well in conditions when the relative humidity is up to 95%. Installation is possible at heights of up to 1000 meters above sea level, according to its design. Data handling, synchronization, and the execution of machine commands are all supported by its specialized integrated circuits and logic circuits. Computer numerical control (CNC) machining systems are dependable because they combine dedicated memory, logic circuits, and precise timing mechanisms. In terms of performance, the PC board satisfies the requirements of industrial automation.
