Product Overview
The GE IS200SSCAH2AGD is a Simplex Serial Communication Input/Output (SSCA) terminal board designed for the Mark VI control system. It provides up to six serial communication channels, each configurable for RS-232C, RS-422, or RS-485 signals, making it a versatile interface for gas and steam turbine automation.
This board works with the PSCA I/O pack, which connects to the controller via Ethernet and plugs into the board's DC-37 pin connector. The IS200SSCAH2AGD is a reliable, surface-mount technology board built for demanding industrial environments.

Applications
The IS200SSCAH2AGD is ideal for turbine control retrofits and upgrades. It handles serial communication between the Mark VI controller and field devices such as vibration monitors, excitation systems, and remote I/O panels. Its multi-protocol capability allows seamless integration into legacy and modern systems.
In a typical retrofit, the IS200SSCAH2AGD replaces older communication boards, providing reliable data transfer while reducing wiring complexity. The board's compact size (15.9 cm x 10.2 cm) fits into existing cabinets with minimal modifications.
Installation & Setup
Mount the IS200SSCAH2AGD on a DIN rail using the sheet metal carrier and plastic insulator mount, or bolt it directly to a cabinet panel. The board features a 48-terminal right-angle header that accepts standard pluggable terminal blocks.
Use #18 AWG shielded twisted pair wiring for optimal signal integrity. Connect the shield ground to one of the SCOM terminals (37-48). For RS-422/RS-485, set the termination resistors using jumpers JP1A-JP6A (lines A/B) and JP1B-JP6B (lines C/D).
Compatibility & Integration
The IS200SSCAH2AGD is designed for the GE Mark VI Speedtronic system. It works with the PSCA I/O pack, which communicates over Ethernet. The board supports RS-232C, RS-422, and RS-485, making it compatible with a wide range of serial devices.
Maintenance & Reliability
Regular inspection of the terminal connections and jumpers ensures reliable operation. The surface-mount technology and robust design contribute to long service life. The ID device allows the PSCA I/O pack to verify board identity, reducing the risk of hardware incompatibility faults.
Selection Guide
When selecting a replacement board, verify the exact part number IS200SSCAH2AGD to ensure compatibility with your Mark VI system. Check the board's revision and connectors. PLC Source PRO offers this board in stock, ready for immediate shipment, backed by our commitment to quality and reliability.
