GE A16B-2200-0853 PLC Board | 20MHz, 80 I/O, 12-Bit ADC

Core Processing Capabilities

The GE A16B-2200-0853 executes machine control logic for industrial automation. This PLC control board serves as the central processor in Fanuc CNC systems. It manages axis motion, spindle control, and auxiliary functions. Consequently, the module ensures precise coordination of machining operations.

Physical Dimensions and Board Construction

This PLC control board measures 265 mm in total length. Its width reaches 200 mm for a full-size PCB form factor. The board thickness stands at 22 mm including all component heights. You will find 876 discrete components on this six-layer substrate. These include a main CPU, memory ICs, and interface controllers. The GE A16B-2200-0853 weighs approximately 580 grams for secure mounting.

Processor and Memory Configuration

The GE A16B-2200-0853 houses a 16-bit microprocessor running at 20 MHz. This CPU executes ladder logic and sequence control programs. The board contains 1 MB of flash memory for firmware storage. It also includes 512 KB of static RAM for runtime data. A replaceable lithium battery preserves the RAM contents during power loss. This battery provides a typical retention period of three years.

Input and Output Interface Summary

This PLC control board provides 48 digital input channels for field devices. It also offers 32 digital output channels for actuator control. Furthermore, the module includes 8 analog input channels with 12-bit resolution. The board uses four 36-pin connectors for all field wiring interfaces. A dedicated 20-pin header serves the hand-held pendant connection.

Communication Ports and Networking

The GE A16B-2200-0853 offers one RS-232 port for programming and debugging. It also provides one RS-422 port for high-speed device communication. Furthermore, the module includes a proprietary CNC bus interface for axis control. Six status LEDs indicate processor health, communication, and program execution. A 9-pin D-sub connector serves the main programming interface.

Energy Storage and Power Requirements

The GE A16B-2200-0853 draws 650 mA from a 5 V DC logic supply. It also requires 120 mA from a separate 24 V DC I/O supply. The board incorporates eight 100 µF tantalum capacitors for power decoupling. Total stored energy reaches approximately 0.06 joules at nominal voltage. The module dissipates 4.5 W of heat during normal operation.
