Product Description:
The E4809-015-167-B is a CMOS memory board manufactured by Okuma and is intended for industrial automation. This module is a non-volatile storage option for CNC machines and control units. It keeps data even when the power goes out. It has backup power and SRAM chips to keep important system parameters and software data.
The E4809-015-167-B memory board contains Hitachi's HM628128 SRAM processors. Each unit is configured as 128K x 8 bits and contains 128 KB of memory. The board has many chips arranged so that it can hold enough part programs and tool data. A pack of four UM-3 AA batteries provides backup power for the SRAM, so data is kept even when there is no external source. For safe program storage, the board has EPROMs like the HN27C301 and HN27C256. These EPROMs are known for being stable, so they can be used for a long time in commercial settings. Using both through-hole and DIP (Dual In-line Package) ICs makes the board last longer and be easier to maintain, which is especially important in demanding systems like CNCs. Headers and jumper links will be used to make it easy and open for system lines and peripheral parts to communicate with each other. Overall, the board's design puts a lot of weight on data security, long-term dependability, and smooth operation in CNC settings. This makes sure that it works well and can be maintained for a long time.
The E4809-015-167-B memory board functions by utilizing CMOS technology, which consumes minimal power. It is compatible with the majority of CNC control systems and is capable of operating within a broad temperature range. With its battery-backed SRAM setup, the board makes sure that data stays safe over time.
