GE IS200EROCH2A IS200EROCH2ABC | Exciter Options Card

Enhanced Functionality for GE EX2100 Regulators

The GE IS200EROCH2A IS200EROCH2ABC adds extra I/O capabilities to the exciter regulator. This options card belongs to the Mark VI series from General Electric. It plugs directly into the main regulator board. Therefore, it expands control features without replacing the entire chassis.

Compact Dimensions and Lightweight Build

This options card measures 10 cm in width, 8 cm in height, and 1.5 cm in depth. The GE IS200EROCH2A IS200EROCH2ABC weighs approximately 0.09 kg, which makes it extremely portable. Its small form factor fits into any dedicated option slot. Consequently, you can install it in seconds without special tools.

Connector Layout and Component Configuration

The GE IS200EROCH2A IS200EROCH2ABC features one 40-pin expansion connector for regulator interface. It also provides two 10-pin auxiliary ports for external signals. This card contains four opto-isolator chips for input protection. Additionally, it includes two small energy storage capacitors for stable logic operation.

This storage prevents voltage drops during simultaneous output switching. Furthermore, the opto-isolators provide 2.5 kV isolation between field and logic sides.

Role Within the EX2100 Excitation System

You will typically find the GE IS200EROCH2A IS200EROCH2ABC mounted on the main regulator board. It adds eight digital inputs and six digital outputs to the base configuration. Moreover, this card supports both sinking and sourcing output types. Its expanded I/O allows you to monitor additional field devices.

Installation and Configuration Steps

Use the GE IS200EROCH2A IS200EROCH2ABC as a direct upgrade for standard regulator boards. Always power down the exciter rack before inserting this card. The 40-pin connector aligns with a single orientation key. This design prevents incorrect insertion during maintenance. Simply push the card firmly until the retaining clips engage.
