GE DS200ADMAH1AAC analog module sub-board

The DS200ADMAH1AAC is an analog-to-digital module sub-board by General Electric (GE), belonging to the Mark V series, primarily used in industrial automation and control systems. The following is a detailed introduction:

Main FunctionsSignal Conversion

It can convert analog signals into digital signals for processing and analysis. Meanwhile, it also converts digital control signals into analog output signals for precise control of external devices.

Signal Processing

Buffers, filters, and converts analog and digital I/O signals sent to and from the board to ensure signal stability and accuracy, enabling better system recognition and processing.

Provision of I/O Points

In addition to the driver's own input/output points, the board provides an additional 8 digital input and output points for users to meet more control requirements.

System Interface Implementation

Equipped with integrated programmable logic devices, it achieves communication between the sub-board and the DPSC (Digital Signal Processing Card) processor bus through logic control in the form of static RAM, enabling better collaboration with the entire system.

Status Indication

Features LED status indicators that provide diagnostic and board status information, facilitating users to promptly understand the module's operating status for maintenance and fault troubleshooting.
