Product Description:

This E4809-032-504-C circuit board is designed and produced by Okuma. The company is one of the largest electrical and electronics automation equipment manufacturers in the world. Okuma manufactures a lot of industrial products such as servo motors, drive controllers, amplifiers, and many more.

The E4809-032-504-C circuit board consumes a main card 6 that is a printed circuit board used in industrial systems. The board features several integrated circuits arranged in a grid. Components include TA7718P which is used for control functions and Philips 74LS244 buffers that help manage signal flow. Also, it contains some of the logic ICs such as the HD74LS32P OR gates and M5M51008BP SRAM chips used for short-term data handling. A TDK CP-3603 processes filtering operation and this E4809 series board contains a large ribbon cable connector that allows it to interface with other modules or systems. Some passive components are positioned for power filtering and signal stability. The layout is clean with printed silkscreen labels for easy identification and service. The Gold-plated mounting points on the corners are used for secure installation in a chassis.

The E4809-032-504-C circuit board’s green solder mask clearly reflects a standard industrial design. It operates using TTL logic which suggests a 5 V power requirement. This board is not designed for standalone use but rather as a part of the control structure in a CNC machine. The board can even work in high humidity levels that lie above 90% and without condensation. Its overall composition of various components and small mass of less than 1 kg suggest it is built with proper service, design and reliability.
