Product Description:
The E4809-770-107-D Circuit Board from Okuma stands out as a proficient device that specifically meets requirements for industrial automation purposes with high capacities. The company leads the industry with efficient motors, boards and drives by applying innovative techniques to their manufacturing process.
The E4809-770-107-D circuit board functions as an interface module within CNC machines and appears in most such systems. One of the core elements includes two custom hybrid category integrated circuits such as ASICs that perform signaling process and machine control operations. The eight coaxial connectors running along the top edge of the module potentially use BNC or SMA connection types to transmit analog signals and accept encoder feedback. Besides eight coaxial connectors BNC or SMA types, the E4809 series CNC board uses at least two EPROM chips using 28-pin DIP types such as M27C256 or M27C512 to store firmware or machine-specific settings. The EPROM chips exhibit reliability and provide access times ranging from 90 to 120 nanoseconds while operating reliably in industrial environments. Standard TTL and CMOS logic Integrated Circuits perform digital logic operations to route data signals through the main setup.
The E4809-770-107-D circuit board has ceramic capacitors that are distributed throughout the board and rated around 0.1 micro-farad for decoupling purposes near IC. A crystal oscillator is also present which aids in providing clock pulses to timing-dependent circuits. It uses CE certification and follows standard safety rules and regulations. The layout suggests a double-sided design with a mix of surface-mount and through-hole components. It is mainly created for specialized use in precision equipment by providing reliable data handling and interfacing within a larger control architecture.
