Main Functions

1. Provides field‑wiring termination and signal routing between Mark V / EX2000 control hardware and external field sensors, actuators and excitation‑system devices. Integrates surge‑suppression circuits to mitigate plant‑site electromagnetic interference.
2. COREBUS connectors transfer processed I/O signals to main controller boards. RS‑232 serial port supports local diagnostic connection for commissioning and troubleshooting. BNC connectors handle high‑speed analog measurement signals.
3. No dedicated on‑board LED array; signal health and fault conditions are monitored via main controller diagnostic menus and system alarm logs.

Installation & Wiring Requirements

1. Cut off full rack power supply before installation or replacement. Non‑hot‑swappable. ESD wrist‑strap protection is mandatory during board handling.
2. Secure DS200CTBAG1ADD to cabinet rack with mounting screws. Double‑check every field‑wiring terminal assignment matches original drawing. Fasten COREBUS headers, RS‑232 port and BNC signal connections.
3. All field wiring shall strictly follow Mark V / EX2000 system wiring drawings. Reliable protective‑earth connection for control cabinet is mandatory.
4. After replacement: Restore rack power supply. Verify controller I/O point status. Perform signal‑loop injection tests for critical excitation and turbine‑protection channels. Confirm interlock and protection‑logic responses.
5. Replacement note: Wrong terminal wiring will cause excitation mis‑operation or false turbine trips. Full‑system commissioning and protection‑logic verification test is mandatory before putting turbine‑generator control into service.
