Overview
The ABB SDCS-FEX-2 (3ADT306311P2103) is a critical field excitation board in ABB’s DCS 500 and DCS 600 DC drive platforms. It precisely regulates field current supplied to DC motor windings, enabling stable torque output and accurate speed control. Typically installed inside the armature converter module—adjacent to the SDCS-POW-1 power supply board—it plays a central role in motor performance and protection.
Moreover, this board supports high-voltage and high-current field excitation, making it a reliable solution for heavy industrial applications including steel rolling mills, paper production lines, and large conveyor systems. Its compact yet rugged design ensures dependable long-term operation in harsh environments.
In addition, seamless integration with ABB drive control modules helps reduce commissioning effort and simplifies maintenance procedures. Engineers leverage it to ensure consistent drive response and safeguard the field circuit from overloads or faults.
