GE DS200SIOCG1AEA Instantaneous Overcurrent Card

الوصف

The GE DS200SIOCG1AEA is a highly specific I/O board designed for the GE Mark V Speedtronic Turbine Control System.¹ It functions primarily as an Instantaneous Overcurrent Card and serves as an I/O expansion module within the system’s ²$\text{VME}$ rack.³

Its key role is to provide a fast-acting protective function for critical turbine or drive equipment, in addition to managing control signals.

Core Function and System Integration

• Primary Function: To act as an Instantaneous Overcurrent Protection device. It continuously monitors current levels in a circuit. If the current exceeds a pre-set high threshold (the “instantaneous” level), the card is designed to quickly trigger an alarm or send a trip signal to the circuit breaker to interrupt the current flow, preventing immediate damage to expensive components.⁴

   

• System Integration: It is part of the DS200 Mark V Series and is a ⁵$\text{VME}$ standard board.⁶ It plugs directly into a $\text{VME}$ rack to communicate with the central turbine controller ($\text{SC}2000$ or $\text{UC}200\text{V}$) via the $\text{VME}$ bus.

   

• Connectivity: Unlike the ribbon-cable based $\text{SIOB}$ boards, the SIOC boards are typically equipped with wire terminal blocks (like $\text{TB}-1$ through $\text{TB}-5$) to allow direct screw-down wiring of signal wires, often up to 33 signals, directly to the board.
