Product Description:
The E4809-032-474-A circuit board controls all essential signals and processing operations using a central control unit to connect processors to input and output system parts. Okuma designed this board by applying its widely known vigorous flexible technology to handle multiple processes smoothly.
The E4809-032-474-A circuit board is categorized under main card 4-2 configuration. It integrates multiple low-power Schottky TTL logic ICs by including the HD74LS series such as 04P, 08P, 32P and 245P. These ICs are arranged for logic signal routing, bus driving and data gating functions. Address decoding is managed through 3-to-8 line decoder chips such as HD74LS138P which assist in memory access and logic control sequences. The board also contains octal bus transceivers to enable controlled bidirectional data flow across system buses. Onboard components include multiple ceramic capacitors rated at 0.1 micro-farad for decoupling noise from IC power lines, and an electrolytic capacitor marked 47 micro-farads for filtering lower-frequency voltage fluctuations. It has several resistor networks as 10K×8 arrayed and discrete resistors by aiding in signal stabilization and logic level control. It works with a 27-series EPROM having capacity between 32 KB and 256 KB.
The E4809-032-474-A circuit board involves a feature of electromagnetic interference suppression which is supported by a toroidal coil in the power section by working with capacitors to filter out noise. It is silkscreened and every component is PCB hole mounted by highlighting its compatibility with traditional soldering and maintenance methods. All sections are logically grouped by ensuring efficient control over machine operations within the CNC control unit. Connectors marked with CN-M-4-2-1 and CN-M-4-2-2 provide direct plug-in connections to other OPUS 5000 modules or the system backplane.
