The DAPC100 is a control board used in ABB high-performance drive systems, functioning as the main processor board with analog input capability. It manages motor speed/torque control loops by processing signals and issuing commands with high precision. The board is equipped with a 24 V DC powered microcontroller/DSP and includes 2 analog input channels (e.g. ±10 V or 0/4–20 mA for feedback signals) with 16-bit A/D conversion for accurate sensor readings. It also provides multiple fieldbus and device interfaces – including Ethernet, Modbus, PROFIBUS, CAN, and RS-485 – via its communication ports, allowing integration into broader control networks. The DAPC100 board has on-board memory for program and data storage and supports advanced features like real-time clock and non-volatile parameter memory. It mounts on a DIN-rail or panel and can operate from –20 °C up to +70 °C, suitable for control cabinets in harsh environments. With a rugged IP20 construction and conformal coating, it endures vibration and dust. In summary, the DAPC100 is the brains of an ABB drive/control system, combining drive control functions (like analog setpoint processing and device interfacing) on a single board, and enabling high-speed closed-loop control with fewer components needed to achieve Performance Level e (when used in safety-rated configurations).
