Product Description:
The E4809-770-087-C circuit board belongs to the OPUS7000 MPM series from Okuma and is part of the control hardware installed in machine tool systems. Okuma develops high-class boards to solve various embedded and electronic industrial issues.
The E4809-770-087-C circuit board functions as a module within the CNC control architecture which is responsible for coordinating data signals, managing I/O pathways and interfacing with peripheral modules. It is structured with a set of logic ICs, timing components, memory units and connection ports distributed across a double-sided PCB layout. It includes multiple 74-series TTL logic ICs such as 74HC244, 74HC240A and ALS273 types used for line driving, buffering and latching data between sections. A series of 74HC04 inverters and ALS197 counters provide signal handling and counting functions within logic paths. Integrated circuit components are socket-mounted or directly soldered for fixed operation. Clock synchronization is provided by a 33.000 MHz crystal oscillator which maintains timing across logic gates and memory interfaces. A Hitachi DC9004L ROM chip is installed in a socket and holds interfacing instructions that define the board's role in data flow regulation. This PCB supports appropriate signal communication between machine control logic and motion elements which aids in enabling proper operation in an industrial automation environment.
The E4809-770-087-C circuit board’s component selection follows a standard 5 V logic voltage with a routing network. It serves as a control rack system by allowing signal coordination without active computation. Ceramic capacitors for noise decoupling on high-speed lines, passive resistors, and electrolytic capacitors for power smoothing are all part of the design. Data and control lines are transferred to additional modules or sensor interfaces using connectors designated XB2 through XB12. These consist of larger multi-pin rectangular headers and blue high-density D-sub type connections.
