High-Performance Control Core for ACS800 Drives
This power control board is a core component of the ABB ACS800 drive series. The RMIO-02C handles critical tasks like logic execution and I/O management for the entire drive system. It also features a dedicated DSP for precise speed and torque closed-loop control. Notably, this board uses fiber-optic communication for robust, noise-immune signal transmission. This makes it the preferred choice for high-power and multi-drive applications.
Comprehensive Technical Specifications
The RMIO-02C operates on a nominal 24V DC supply for its control circuitry. It provides a rich set of I/O, including 6 digital inputs and 3 relay outputs. For analog signals, it offers 2 inputs (0–10V / 4–20mA) and 2 outputs (0–10V). The board connects to an AINT fiber-optic driver board and supports an optional encoder interface. It also includes an expansion slot for fieldbus adapters like Profibus or Modbus. The module measures approximately 50mm x 120mm x 290mm and weighs around 0.18kg.

Integration and Application
This control board serves as the central intelligence for managing inverter operations. First, mount the RMIO-02C securely within the drive cabinet. Then, connect the fiber-optic cable to the corresponding AINT driver board. For external control, wire the digital and analog I/O to their respective terminals. Additionally, the board communicates with the CDP-312R control panel via a dedicated port. It is essential for applications such as fans, pumps, and conveyors in demanding sectors like mining, paper, and steel.
