IS200EXHSG3AEC GE EX2100, Exciter High-Speed Relay Driver Board

Description:

The IS200EXHSG3AEC is an Exciter High-Speed Relay Driver Board  of the GE Industrial Systems, specifically designed as part of the EX2100 Excitation Control series. The EX2100 series is one of General Electric's most popular turbine management systems, featuring a Triple Modular Redundant (TMR) design for enhanced reliability. This system is responsible for producing the excitation current required to control AC terminal voltage and reactive volt-amperes in both new and retrofit steam turbines, as well as gas and hydro turbine generators.

The IS200EXHSG3AEC serves as a Static Exciter High-Speed Terminal board within the EX2100 system. It includes several key hardware components:

- A solid-state relay driver
- Seven relays
- Integrated circuits
- Transistors
- Capacitors
- Resistors made from metal film and carbon composite materials

Additionally, the board features three D-shell vertical pin connectors and eight plug connectors of various sizes. It also has several wire jumpers pre-installed by the manufacturer for initial voltage testing.

Upon visual inspection, the PCB edges are drilled, with some of these drillings ringed with a conductive material. Two corners of the board are clipped away, and there are four small notches on the front edge for mounting purposes within the drive assembly.

Despite some initial mystery surrounding its release, the IS200EXHSG3AEC is clearly labeled to aid in understanding its functionality and compatibility. For instance, the sizable relays on the base board follow the industry-standard "K" relay nomenclature, each labeled with a specific relay code such as K53B_C and K53A_M1. In addition to relays, the board uses over fifty capacitors for energy storage and more than one hundred resistors.

All hardware components are securely protected behind a traditional layer of normal-style PCB coating, which provides a solid base protective layer suitable for specialized automated needs. However, it should be noted that this coating is not as exhaustive as special conformal-style PCB coatings.

For further information on the functionality or proper installation of the IS200EXHSG3AEC, refer to GE Industrial Systems manuals or user guides that should have accompanied the original product. It is crucial to review warnings and handling procedures in these publications before unboxing and using the new part.
