I/O modules

The GE DS200IOEAG1A DS200IOEAG1ADB add additional I/O capacity to GE Mark V turbine systems. These I/O expansion boards connect to the main turbine control through a dedicated bus. You can use either board to monitor extra sensors and actuators. The units provide both analog and digital signal interfacing capabilities.

I/O and Electrical Specifications

The GE DS200IOEAG1A DS200IOEAG1ADB expand I/O capacity for Mark V controllers. These I/O expansion boards offer 8 analog inputs and 4 analog outputs. You can also access 16 digital inputs and 16 digital outputs. The units provide 12-bit resolution for precise analog measurements.

Physical Dimensions and Weight

Each I/O expansion board weighs 0.52 kg for secure chassis mounting. The unit measures 280 mm long by 165 mm wide. Its PCB thickness reaches 1.6 mm with six internal copper layers. You can mount either board using six M4 screws through the designated holes.

Interface and Connection Points

Two 50-pin ribbon cable headers connect to the main turbine controller. Six 10-pin terminal blocks handle field wiring for all I/O points. The GE DS200IOEAG1A DS200IOEAG1ADB include a 4-pin power input connector. You will find 44 LED indicators showing status for each I/O channel. Additionally, eight test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These I/O expansion boards store moderate energy for signal filtering purposes. Sixteen electrolytic capacitors provide 1,200 µF of total bulk storage. These capacitors smooth power supply ripple for the analog circuits. The boards do not contain any battery for configuration retention. A separate EEPROM stores calibration data for the analog channels.

Component Layout and Construction

A dedicated I/O processor manages all scanning and data transfer tasks. Sixteen optocouplers isolate digital inputs from the internal logic. You will find 142 resistors, 98 capacitors, and 18 integrated circuits on the board. The GE DS200IOEAG1A DS200IOEAG1ADB include transient suppression on all I/O points. A metal shield covers the processor section for noise reduction.

Variant Equivalence and Use

The GE DS200IOEAG1ADB represents a functional equivalent or later revision. Both versions share identical dimensions, connectors, and mounting hole locations. You can substitute one for the other without hardware modifications. Transitioning to these boards expands your Mark V I/O capacity significantly. Use GE DS200IOEAG1A DS200IOEAG1ADB for additional sensor monitoring in turbine control applications. For best results, use shielded cables for all analog signal wiring.
