Product Overview
The GE DS200UCIAG1ACC MARK V Relay Board is an industrial relay interface board designed for use within GE turbine control and automation systems. As a member of the DS200 family, it provides discrete relay-based switching functions between control-system circuitry and external electrical equipment.
Relay boards are used when a control system needs to transmit discrete ON/OFF commands, status signals, alarm indications, or interlock conditions to external circuits. In turbine automation, these functions can be associated with auxiliary equipment, control devices, annunciation systems, and other discrete field interfaces.
The DS200UCIAG1ACC is intended to operate as part of a larger control-system architecture rather than as an independent controller. Its relay circuitry works together with processors, I/O modules, terminal interfaces, and associated turbine-control hardware.
The specified dimensions of the DS200UCIAG1ACC are 220 × 100 × 30 mm, with a specified weight of 0.18 kg.

Function and Working Principle
The primary function of the DS200UCIAG1ACC is to provide relay-based switching for discrete control signals.
In a typical control architecture, a processor or I/O module determines when a particular output should change state. The corresponding signal is routed to the relay interface, where the relay changes its electrical state and provides the required output to the external circuit.
A simplified signal path can be represented as:
Control Processor → I/O Logic → DS200UCIAG1ACC → Relay Circuit → Terminal Interface → Field Device
This arrangement allows low-level control-system logic to interface with external electrical equipment.
Depending on the application, relay outputs may be associated with:
- Equipment status
- Alarm indication
- Auxiliary control
- Interlocking
- Permissive signals
- Solenoid interfaces
- Discrete commands
- Control-system status
- External equipment enable signals
The exact function of individual relay circuits depends on the system configuration and wiring.
The DS200UCIAG1ACC therefore serves primarily as an electrical interface between control-system electronics and external discrete circuits.
Role in Industrial Control Systems
The DS200UCIAG1ACC can form part of a larger GE industrial control architecture where relay-based outputs are required.
A control system normally contains several functional levels. Processor boards execute control logic, I/O hardware processes signals, terminal boards provide field wiring connections, and relay boards provide electrical switching between the control electronics and external devices.
The DS200UCIAG1ACC can participate in this output interface layer.
It may work alongside:
- Control processor boards
- Digital I/O modules
- Terminal boards
- Relay interface hardware
- Turbine control equipment
- Alarm systems
- Interlock circuits
- Solenoid devices
- Auxiliary equipment
- Control cabinet wiring
Its relatively low weight of 0.18 kg also makes it a compact component compared with larger turbine-control boards.
Industrial Applications
The GE DS200UCIAG1ACC can be used in industrial automation and turbine-control environments where discrete relay interfaces are required.
Typical applications include:
- Gas turbine control systems
- Steam turbine control systems
- Power-generation automation
- Industrial turbine packages
- Auxiliary equipment control
- Discrete alarm systems
- Interlocking systems
- Equipment status interfaces
- Industrial control cabinets
- Legacy GE automation systems
Relay-based interfaces are particularly useful where external equipment does not communicate directly through a digital network and instead requires conventional electrical contacts.
For example, a relay output can provide an enable signal, alarm indication, equipment status, or command to another electrical control circuit.
Installation and System Integration
Proper installation is important because relay boards can directly interface with external control circuits.
Before replacing a DS200UCIAG1ACC, technicians should identify the original board position and document all wiring and connector assignments.
Recommended installation procedures include:
- Follow the approved equipment shutdown procedure.
- Isolate the appropriate control-system power.
- Verify the complete DS200UCIAG1ACC part number.
- Record the board revision information.
- Document existing cable and connector positions.
- Compare the replacement board with the original.
- Inspect the replacement PCB for physical damage.
- Check connectors and relay components.
- Install the board in the designated cabinet position.
- Reconnect all cables according to the original configuration.
- Verify terminal-board wiring.
- Check associated discrete circuits.
- Restore power according to approved procedures.
- Check system diagnostics.
- Verify relay operation.
- Confirm the expected field-device response.
- Perform functional testing before returning equipment to service.
ESD protection should be used when handling the PCB.
Because relay outputs can affect external equipment, correct wiring is essential. Technicians should verify the complete signal path and not rely only on physical dimensions or board appearance when determining compatibility.
Compatible System Components
The DS200UCIAG1ACC may operate with several components in a GE industrial control system.
| Component | Function |
|---|---|
| Control Processor | Executes programmed control logic |
| Digital I/O Hardware | Processes discrete control and status signals |
| Terminal Boards | Provide field wiring interfaces |
| Relay Interface Circuits | Support discrete electrical switching |
| Alarm Systems | Provide equipment and process status |
| Interlock Circuits | Implement permissive and control conditions |
| Solenoid Devices | Receive discrete commands |
| Auxiliary Equipment | Receives control signals |
| Control Cabinet | Houses control-system hardware |
| Field Wiring | Connects control hardware to external equipment |
The exact combination depends on the original equipment configuration.
Recommended Alternative Models
The following models may be considered when evaluating related GE relay and control-interface hardware:
| Model | Type | Key Feature | Application |
