Product Description:

The E4809-045-074-B is one of Okuma’s best-selling circuit boards, manufactured for automation and CNC applications. It features a large number of integrated circuits, nonlinear elements, and microprocessors for handling both analog and digital signals during operation. For most electrical devices and circuit boards, digital and analog processing blocks are usually integrated to generate appropriate output signals based on some inputs. For most circuit boards, the inputs can be both digital and analog or a mixture of both. In the context of automation systems, analog inputs can come from pressure valves, spindle motion, and other continuous signals. On the other hand, digital inputs can come from other modules or devices.

The E4809-045-074-B features a set of peripheral ports, perfect for connecting other modules or devices. The peripheral ports are then connected to the CNC board’s signal processing blocks, which allows the other circuit blocks to perform decoding. In the context of electronic devices, decoding blocks are usually employed to process a series of digital signals based on some communication protocol. Aside from the connection ports, the E4809-045-074-B also features a multi-pin contact. The multi-pin contact can be used to directly connect the whole CNC board to a compatible control panel or electrical module. Together with other CNC boards or control panels, the E4809-045-074-B can perform advanced signal processing and control functions.

Like all other circuit boards manufactured by Okuma Corporation, the E4809-045-074-B can be used safely within an ambient operating range of 0 to 45 degrees Celsius. Since the E4809-045-074-B is marketed as a CNC circuit board, it does not come with a chassis or cover. Assuming this CNC board will be used as a replacement for an existing CNC module or device, the original chassis of the product can be reused.
