Product Description
The SDCS-FIS-3A is engineered specifically for use in ABB’s DCS drive systems. It manages the interface between the drive’s control board and the field circuits (such as field windings or excitation supplies). By converting, isolating and conditioning both analog and digital signals, the module ensures the control system receives clean, reliable feedback from the field side and sends accurate commands back.
In application it supports galvanic isolation to protect control electronics from the high-voltage field side. It supports a wide range of field currents and voltages, making it suitable for many armature / field converter modules. The board is built for industrial durability, designed to withstand vibrations, elevated temperatures, and harsh ambient conditions typical in steel mills, heavy manufacturing or mining operations.
By using this board, drive systems achieve enhanced feedback accuracy (improving torque and speed regulation), reduced signal interference and improved overall stability of the DC motor and drive loop.
