GE IS200SPIDG1ABA Power Supply Module

GE IS200SPIDG1ABA

The GE IS200SPIDG1ABA is a LAN Communications Card (SLCC) for the GE Mark V / Speedtronic turbine and drive control system. It is designed to provide communication functions between the host drive/control system and the associated LAN networks.

1. Product Overview

The G1 version of the SLCC is associated with DLAN and ARCNET communication circuitry and provides both isolated and non-isolated communication functions.

2. Technical Parameters

• LAN control processor (LCP): Integrated processor responsible for LAN communication functions.
• Memory: Two onboard/removable EPROM modules provide program memory for the LCP.
• Dual-port RAM: Provides the communication interface between the LCP and the connected drive control board.
• Network support: DLAN and ARCNET for the G1 configuration.
• Host interface: The 3PL connector interfaces with the drive control card, such as the IS200SPIDG1ABA.
• Display/diagnostics: The board can support an alphanumeric keypad/display for accessing control settings and diagnostic information.

Note: Some third-party listings provide conflicting specifications for voltage, Ethernet speed, dimensions and temperature range. Those figures should not be treated as authoritative for the IS200SPIDG1ABA without the GE documentation. The GEI-100162 manual is the safer reference for installation and electrical specifications.

3. Product Features

1. Dual-network communication — G1 configuration supports both DLAN and ARCNET.
2. Integrated LAN processing — LCP handles communication processing.
3. Dual-port RAM architecture — facilitates high-speed data exchange between the communication processor and drive control electronics.
4. Isolated and non-isolated interfaces — suitable for different industrial communication configurations.
5. Diagnostic capability — compatible with an alphanumeric keypad/display for system monitoring and troubleshooting.

4. Structural Composition

The  IS200SPIDG1ABA is a printed circuit board assembly incorporating:

• LAN Control Processor (LCP)
• EPROM program-memory modules
• Dual-port RAM
• DLAN/ARCNET communication circuitry
• Interface connectors
• Diagnostic/display interface
• Supporting communication and isolation circuitry

5. Application Fields

The board is primarily associated with GE Mark V Speedtronic control architectures, including:

• Gas turbine control
• Steam turbine control
• Turbine drive systems
• Excitation/control equipment
• Industrial drive systems
• Legacy GE turbine automation systems

Its primary role is communication rather than direct power control—it allows control boards and the wider Mark V system to exchange operational, control and diagnostic information.

6. Conclusion

The GE IS200SPIDG1ABA  is a specialized Mark V SLCC LAN communication board, with the G1 configuration supporting DLAN and ARCNET networks. Its LCP, EPROM memory and dual-port RAM architecture make it an important communication interface within compatible GE turbine/drive control systems. It is a legacy Mark V component, so replacement should be based on the exact board number and revision rather than assuming that visually similar SLCC variants are interchangeable.
