Product Description

The ABB SDCS-PIN-H11A is a sophisticated Printed Circuit Board (PCB) that serves as a Power Interface Board within high-power DC drive converter units. Its primary function is to provide the critical interface and isolation required between the main power circuit of the drive (the thyristor power section) and the low-voltage control unit (the SDCS-CON board).

It handles essential functions such as:

• Voltage Measurement: Routing signals for the drive’s input and output voltage measurement.

• Signal Isolation: Providing electrical isolation for voltage and current signals to protect the sensitive control electronics.

• Power Distribution: Distributing auxiliary power supplies to the control and I/O boards within the drive system.

• Overvoltage Protection (OVP): The “A” revision, SDCS-PIN-H11A, often replaces the older SDCS-PIN-H11 and the separate SDCS-OVP-H11 board, integrating enhanced protection features directly onto the interface board.

Product Parameters

Product Advantages

• Enhanced Reliability: The SDCS-PIN-H11A is a revised version that often incorporates design improvements and integrated features for better stability and longevity compared to its predecessors.

• Critical Isolation: Provides robust electrical isolation of high-voltage signals, crucial for protecting the sensitive programmable control electronics (SDCS-CON) from power disturbances.

• System Integration: Designed to be a seamlessly integrated component of ABB’s high-performance DC drive families, ensuring compatibility and simplified maintenance.

• Space Optimization: Integrating the overvoltage protection (OVP) function into the main interface board helps reduce the overall footprint inside the drive cabinet.

Precautions

• Electrostatic Discharge (ESD): As a sensitive PCB, it must be handled only with proper ESD protection (e.g., grounded wrist straps) to prevent damage.

• High Voltage Risk: This board deals directly with connections to the main power circuit of the DC drive. Dangerous high voltages can be present even when the motor is stopped. Mains power must be disconnected and locked out before any installation or maintenance.

• Compatibility: Ensure the revision code (‘A’) is compatible with the specific model and firmware of your ABB DC drive (e.g., a DCT880 frame size T6 may require this specific revision).

• Professional Installation: Installation and replacement should only be performed by qualified personnel familiar with ABB drive systems and electrical safety protocols.

Product Applications

The SDCS-PIN-H11A is essential for the operation of high-power DC drive systems in various heavy industrial applications:

• DC Motor Control: Part of the control loop for regulating the speed and torque of large DC motors.

• Rolling Mills: Used in the metal industry for precise control of steel and aluminum rolling processes.

• Mining and Conveying: Controlling high-power conveyor systems and other heavy-duty rotating machinery.

• Cranes and Hoists: Providing reliable power and control for lifting and moving heavy loads.
