E4809-032-504-B by Okuma

The Okuma E4809-032-504-B servo drive board, part of the E4809 CNC Boards series and manufactured by Okuma, is a robust Type rated for Voltage Rating operation across Phase systems. Engineered for industrial automation, it delivers reliable power for Power Output servomotors while supporting both Frequency input and Feedback Supported encoder loops. The board’s core logic is built around SN74LS04N hex inverters, SN74LS138N 3-to-8 line decoders, SN74LS32N OR gates, and SN74LS00N NAND gates, ensuring precise signal processing and address decoding. A TDK CP-3603 filter module is mounted alongside multiple radial electrolytic capacitors rated between 10–100 micro-farads for voltage smoothing and transient absorption. With integrated overcurrent, Protective Features, and Overvoltage safeguards, this unit is tailored to maintain operational integrity under variable loads.

Performance characteristics are optimized by a Cooling Method system that ensures thermal stability in continuous operation, complemented by built-in Overtemperature protection for enhanced safety. High-density edge connectors support versatile Communication Interface modes, including pulse, analog, or network protocols as detailed in the Okuma manual. The dual-layer fiberglass PCB uses silk-screened identifiers and segmented zones (A, B, C) for efficient signal tracing and maintenance. Fan-cooled airflow maintains a stable internal temperature, while the toroidal inductor near the power section reduces electromagnetic noise and stabilizes current delivery. Panel Mount design allows for seamless integration into OPUS 5000 CNC control cabinets, preserving board alignment and shielding.

Designed for industrial reliability, the E4809-032-504-B operates across an Operational Temperature range of 0–55°C and withstands harsh shop environments. Its encoder feedback support guarantees precise motion control, and the robust overvoltage and overcurrent protection features mitigate risk of downtime. High-density connectors on each side enable straightforward connectivity to adjacent modules in multiboard assemblies, simplifying system upgrades and field servicing. The combination of logical IC arrays, decoders, and capacitors ensures consistent performance for milling, turning, and grinding applications in automated manufacturing lines. As a core component of Okuma’s OPUS 5000 control system, this board underpins high-precision machining operations across diverse industrial automation settings.
