SDCS-PIN-51-COAT 3ADT220090R0006 ABB Measuring Card REV J for DCS800
Overview
SDCS-PIN-51-COAT is a rugged, plug-in interface board engineered for the DCS800 series of industrial DC drives. The board combines two mission-critical functions in a single, compact module:
• Field excitation control – delivers the precise DC current required by the motor’s shunt field, enabling accurate speed and torque regulation.
• COAT (Current Offset & Temperature) measurement – provides high-resolution feedback to the drive’s control logic so field current, armature current and thermal drift are continuously monitored and compensated.
By integrating both tasks, the SDCS-PIN-51-COAT reduces wiring complexity, shrinks panel space and improves overall system reliability.
Key Features
• Dual-channel design – supports both field supply and measurement on one board.
• Galvanic isolation – protects sensitive control electronics from power-stage noise.
• Wide operating envelope – rated for 0…180 V DC field voltage and up to 12 A continuous current; tolerates ambient temperatures from –20 °C to +60 °C.
• Fast signal conditioning – <1 ms update rate for real-time field regulation and current-loop stability.
• Hot-swap capability – board can be replaced without removing the drive from the line, minimizing downtime.
• DIN-rail & screw-terminal options – installs in minutes inside DCS800 power stack or in external enclosure.
