GE IS200EXHSG3A IS200EXHSG3AEC Mark VI Exciter Terminal Card

The GE IS200EXHSG3A card terminates field wiring for exciter control signals. This exciter terminal card also carries the revision code IS200EXHSG3AEC . It connects the excitation system to the Mark VI controller. The card provides organized termination points for reliable field wiring.

Technical Specifications of GE IS200EXHSG3A IS200EXHSG3AEC

Component Count and Board Construction

This GE IS200EXHSG3A card contains over 110 discrete components on its surface. You will find multiple suppression diodes for inductive loads. Furthermore, the card includes fuse holders for output channel protection. The assembly also features LED indicators for each signal path.

Interfaces, Energy Storage, and Signal Routing

The IS200EXHSG3AEC revision provides screw terminal blocks for all field connections. Moreover, the card uses capacitors for minimal noise filtering. These capacitors store very little energy for transient suppression. Each terminal point includes a dedicated test point for troubleshooting.

Functional Logic and Application Context

This Mark VI card routes discrete signals between the exciter and I/O modules. It accepts feedback from field current and voltage sensors. The GE IS200EXHSG3A also delivers output signals to thyristor firing circuits. Additionally, it provides common bus bars for shared power distribution. Consequently, the card simplifies exciter wiring and reduces installation errors.

Installation and Environmental Limits

You must isolate the 24 V DC supply before servicing this terminal card. The operating temperature range spans -30°C to +65°C . Furthermore, the card withstands 5 g vibration without connection loosening. Always verify the IS200EXHSG3AEC labeling against your wiring diagram before connection.
