ABB SINT4130C Printed Circuit Board (Revision G, SINT-41X0 Series)

The ABB SINT4130C is a printed circuit board assembly designed for use in ABB industrial drives, power converters, or control systems. It is part of the SINT‑41X0 family, and this revision G board incorporates upgraded components for improved reliability. Depending on the application, this PCB may function as a gate driver card (for IGBTs), an interface board for analog/digital signals, or a communication link between the main control unit and power stage. SINT4130C boards are typically found in ABB medium‑voltage drives (ACS 2000/5000 series) or DC drive (DCS) systems. The board features high‑temperature laminates, gold‑plated connectors, and conformal coating for harsh industrial environments.

Typical Specifications

Functional Description

In a typical ABB drive, the SINT4130C receives low‑voltage control signals from the main controller (e.g., AMC board) and converts them into high‑power gate pulses for the IGBT modules. It also monitors IGBT saturation voltage (desaturation) for short‑circuit protection and provides feedback signals for current and voltage measurements. The board includes power supply conditioning circuits to generate isolated auxiliary voltages for the gate drivers. Revision G may incorporate improved thermal management and faster fault handling circuits. In some configurations, it may also serve as a communication interface board between the drive’s internal CAN bus and fieldbus modules.

Connector and Pinout Information

The board typically has multiple connectors:

• X1: Power supply input (24V DC, 5V, ±15V) via 2‑ or 4‑pin header

• X2: IGBT gate output and monitoring (to the power stack via ribbon cable)

• X3: Fiber optic interface for command and status (to main control board)

• X4: Analog current/voltage sense inputs (from CTs and PTs)

Exact pin assignments are proprietary to ABB and documented in service manuals.

Revision Differences

The “Rev G” suffix indicates the seventh major revision. Later revisions typically fix known issues (e.g., increased immunity to electromagnetic interference, revised component layout for better heat dissipation, updated firmware for gate drive timing). When replacing a SINT4130 board, it is critical to match the revision as a minimum, and to confirm that the board is compatible with the drive’s firmware version.

Applications

This board is used in ABB industrial drives ranging from 10 kW to several MW, including:

• ACS 800 series (gate driver card)

• ACS 2000 medium voltage drives (interface to power cell)

• DCS 800 DC drives (thyristor firing board)

It is also found as a spare part for drive repair and maintenance.

Installation and Handling

The SINT4130C is an ESD‑sensitive device. Always use a grounded wrist strap when handling. Before installation, inspect the board for cracked solder joints or damaged components. Align the board with the card guides in the drive’s power module, push evenly until the connectors seat fully, and secure with the front panel screws. After replacement, perform a functional test of the drive without the motor attached (if possible), monitoring the gate drive waveforms with an oscilloscope.

Conclusion

The ABB SINT4130C Rev G is a reliable control board for ABB industrial drives, providing essential gate drive, monitoring, and interface functions for heavy‑duty power electronics applications.
