Board Layout and Components
The PCB carries eight static RAM chips arranged in a single row. A lithium battery sits on the right side of the board. Moreover, 68 discrete components include address decoders and bus drivers. The memory chips retain data for six months without CNC power. Consequently, part programs remain safe during extended machine shutdowns.
Installation Process
You can mount GE A16B-1200-0220 into any GE CNC memory expansion slot. The 64-pin DIN connector mates directly with the CNC motherboard. Furthermore, a low battery LED warns operators when replacement becomes necessary. Locking clips secure the board firmly within the memory slot.
Performance Advantages
This board stores approximately 80 meters of punched tape equivalent. The 150 ns access time matches CNC processing speeds perfectly. Therefore, the CNC executes large part programs without waiting for data retrieval. The battery-backed design also eliminates frequent EPROM erasing and burning.
Safety and Compliance
GE A16B-1200-0220 meets CE and RoHS standards. The board discharges stored energy below 3V within two seconds. Hence, technicians face minimal electrical risk during battery replacement.
