GE A16B-2200-0171/05A PC Board – 40 MHz, 2 MB Flash

The GE A16B-2200-0171/05A handles process control functions within CNC systems. This printed circuit board measures 280 mm in width and 200 mm in height. It has a depth of 25 mm, so it fits standard card cages easily. The unit weighs 0.55 kg, making handling during replacement simple.

Processor Architecture and Processing Functions

This PC board contains a 32-bit processor running at 40 MHz. The GE A16B-2200-0171/05A executes PID algorithms for closed-loop process control. It handles up to 8 analog input channels and 4 analog output channels. The board manages spindle speed control and feed rate regulation tasks. A dedicated math coprocessor handles floating-point calculations quickly.

Memory Configuration and Data Storage

The board includes 2 MB of flash memory for firmware and user parameters. The GE A16B-2200-0171/05A also provides 1 MB of SRAM for real-time data storage. A lithium battery preserves SRAM contents during power-off conditions. The battery lasts for approximately 5 years under normal operating conditions. The board stores 220 µF of capacitance for power supply filtering.

Internal Components and Interface Connections

The board contains four major integrated circuits and numerous passive components. The GE A16B-2200-0171/05A includes a 50-pin edge connector for backplane interface. Two 20-pin ribbon cable headers connect to external I/O modules. A 9-pin D-sub connector provides serial communication for diagnostics. LED indicators show power, run, and fault status clearly.

Power Requirements and Environmental Tolerance

The GE A16B-2200-0171/05A draws 500 mA at 5V DC from the backplane supply. It also draws 200 mA at 12V DC for analog circuits. The board operates reliably from 5°C to 45°C ambient temperature. It tolerates humidity levels up to 85 percent without any condensation issues. The unit withstands vibration up to 1g from 10 to 55 Hz.
