Physical Construction and Component Layout

This A16B-2201-0811 PC board measures 7.8 inches in length. Its width reaches 5.6 inches with a thickness of 1.3 inches. The total weight comes to approximately 0.98 pounds. Manufacturers populated this four-layer PCB with 146 discrete components. These components include logic gates, buffers, oscillators, and decoupling capacitors. The board uses a solder mask for corrosion protection.

Interface Connectors and Signal Routing

A16B-2201-0811 features three ribbon cable connectors for external links. Two 50-pin connectors handle high-speed data transfer between boards. One 34-pin connector manages slower status and control signals. Gold-plated contacts resist oxidation for reliable long-term connections. All signal traces follow a controlled impedance design. Consequently, signal reflections remain minimal even at higher clock speeds.

Memory Resources and Processing Support

The PC board includes 256KB of flash memory for firmware storage. An additional 64KB of static RAM handles temporary data buffering. CMOS logic families keep overall power consumption relatively low. The board draws 320 milliamps from the 5V DC supply. Voltage tolerance stays within ±5% for stable digital operation. For energy storage, the board integrates four 47µF tantalum capacitors. Three 220µF electrolytic capacitors provide bulk charge for sudden current demands.

Application Use and System Integration

You will find this board inside GE Series 16 CNC control racks. It serves as a communication or auxiliary logic board. The A16B-2201-0811 operates reliably from 0°C to 55°C ambient. Many machine tools use this PC board for peripheral device handling. For example, it manages operator panel interfaces or pendant connections. Therefore, this board provides reliable signal distribution for legacy GE automation systems.
