Product Description:
The extensive E4809-770-078-A serves as a flexible PC Board for applications requiring precise circuit control and efficiency. Okuma manufactures this product which produces high-quality electrical and electronic designs.
The E4809-770-078-A PC board represents a specialized memory interface board that spends most of its demands in industrial automation systems including CNC controllers alongside PLCs. The memory capability of each HM62256LP chip comes out to 32K x 8-bit which adds up to 512KB throughout all integrated circuits. These SRAM modules enable quick memory operations with 120-nanosecond typically measured access time that control systems require for real-time operations. The static RAM chips, four TC531001CP EPROMs constitute the board enabling 1 megabit (128K x 8) non-volatile storage. This keeps the relay logic tables intact during power interruptions since they remember the control parameters needed for system reloads during startup. The system uses both RAM and ROM devices to handle fast system operations and maintain a stable storage of configuration parameters. It has address bus lines together with control signals and 5V DC power input. It delivers dependable results under industrial conditions because of its strong ICs. The PCB maintains durability through its green solder mask and its gold-plated contacts for enhanced connectivity.
The E4809-770-078-A circuit board functions as a crucial part of legacy FANUC systems alongside similar architectures because it enables relay interfaces and controls input and output states while also functioning as a temporary instruction storage mechanism. The board functions with critical systems because it ensures high-class accuracy and protects data stability and integrity. The board unites volatile and non-volatile memory components that manage real-time data storage and relay state buffering and firmware execution needs. It contains sixteen static RAM (SRAM) chips for reliable working flow.
