Installation and Application Details

The GE installs inside the CNC control cabinet using four M3 screws. Connect the flat ribbon cable to the main backplane for system communication. Attach the RS-232 cable to the 9-pin SUB-D port for programming access. The GE A16B-2201-0480 requires configuration software for parameter setup. Replace the lithium battery every 3 to 5 years to prevent program loss. This circuit board suits milling machines, lathes, machining centers, and grinding machines. It also works perfectly for automated drilling, routing, and cutting equipment. Thus, the GE A16B-2201-0480 provides reliable CNC control for precision metalworking and woodworking applications.
