GE A16B-1211-0920/06A – Graphic Module for CNC Display Systems

The GE A16B-1211-0920/06A generates on-screen graphics for CNC operator interfaces. This graphic module measures 250 mm in width and 200 mm in height. It has a depth of 30 mm, so it fits standard card cages easily. The unit weighs 0.48 kg, making installation in control cabinets straightforward.

Display Resolution and Graphics Capabilities

This graphic module produces a resolution of 640 by 480 pixels on CRT displays. The GE A16B-1211-0920/06A supports both monochrome and color output configurations. It generates text, lines, circles, and custom graphic patterns for machine status. The module includes 256 kB of video RAM for frame buffer storage. It refreshes the display at 60 Hz for flicker-free viewing.

Internal Architecture and Component Layout

The module contains three separate circuit boards stacked inside its metal housing. One board handles graphics generation, while another manages video output. The third board controls communication with the main CNC processor. The GE A16B-1211-0920/06A includes a dedicated graphics coprocessor for fast drawing. A 50-pin edge connector interfaces with the CNC backplane for data exchange.

Memory Configuration and Energy Storage

The graphic module stores 512 kB of firmware in EPROM for fixed functions. The GE A16B-1211-0920/06A provides 128 kB of dynamic RAM for temporary data storage. It stores 470 µF of capacitance across its power filtering circuits. This storage prevents display corruption during brief power interruptions. The module contains no battery, so graphics settings reset after power loss.

Interface Connections and Environmental Tolerance

You will find one 15-pin D-sub connector for analog video output to the monitor. The GE A16B-1211-0920/06A also includes a 9-pin connector for sync signals. It draws 500 mA at 5V DC and 200 mA at 12V DC. The module operates reliably from 5°C to 45°C ambient temperature. It tolerates humidity levels up to 85 percent without any condensation issues.

Below is a complete summary of its technical specifications.

The GE A16B-1211-0920/06A replaces older graphic modules in CNC systems. You do not need any special configuration after installing this module. This unit also supports custom font loading for international character sets. Consequently, it provides clear visual feedback for machine operators.
