The ABB SCC-C 23070-0-102321100000 is a highly specialized and critical component within ABB’s Safety Control & Connectivity portfolio. This product is a redundant high-speed, deterministic communication module designed specifically for the ACS 800 and early ACS 6000 medium-voltage drive platforms. Its primary function is to facilitate safe, reliable, and high-speed data exchange between the drive’s main control system and its dedicated I/O units, often the Remote Input/Output (RIO) modules. The ABB SCC-C 23070-0-102321100000 module forms the backbone of the drive’s internal communication network, ensuring that critical process signals (start/stop commands, speed references, status feedback, alarms) are transmitted with maximum integrity and minimal latency. This is paramount for maintaining precise control and synchronization, especially in multi-drive applications where timing is essential.
As a dual-channel, redundant communication module, the ABB SCC-C 23070-0-102321100000 provides unparalleled system availability. Its redundant architecture means that in the event of a failure in one communication channel, the system can automatically and seamlessly switch to the backup channel without interrupting the drive’s operation, thereby preventing costly process shutdowns. The module is engineered for electromagnetic compatibility (EMC) and robustness in the electrically noisy environment typical of medium-voltage drive installations. For system integrators and end-users, the ABB SCC-C 23070-0-102321100000 represents more than just a communication card; it is the essential nervous system that guarantees the control integrity, diagnostic clarity, and overall reliability of the entire ACS 800/6000 drive system, particularly in mission-critical industrial processes.

Key Features and Advantages
The defining feature of the ABB SCC-C 23070-0-102321100000 is its built-in, high-availability redundant communication architecture. This dual-channel design is not merely for backup; it is a fault-tolerant system that ensures continuous data flow. If a fiber-optic cable is damaged, a connector becomes loose, or the primary channel on the module itself experiences a fault, the system instantly and automatically switches to the secondary channel.

This hot-standby functionality is transparent to the process, preventing unplanned downtime in applications where even a momentary interruption can be catastrophic, such as in rolling mills, extruders, or critical fan/pump systems.
Immunity and reliability in harsh environments are core to its design. By utilizing fiber-optic technology, the ABB SCC-C 23070-0-102321100000 provides complete galvanic isolation between the drive controller and the remote I/O units. This makes the communication link impervious to electromagnetic interference (EMI), radio frequency interference (RFI), and ground potential differences, which are common challenges in high-power industrial settings. This ensures signal integrity, eliminates communication errors caused by electrical noise, and contributes to the overall stability and accuracy of the drive’s control system.
The module also enhances system diagnostics and maintenance. Its status is continuously monitored by the drive’s control software. Detailed diagnostic information—such as channel activity, signal strength, and active/standby status—is readily available through the drive’s local control panel or over the plant network. This allows maintenance personnel to proactively identify issues (e.g., a deteriorating fiber link on the standby channel) and schedule corrective actions during planned maintenance windows, rather than reacting to a failure. The design of the ABB SCC-C 23070-0-102321100000 facilitates straightforward replacement if needed, supporting the drive’s long-term serviceability and lifecycle management.
Application Areas
The ABB SCC-C 23070-0-102321100000 is an indispensable component in any ACS 800 or compatible ACS 6000 medium-voltage drive system where reliability and control precision are non-negotiable. Its primary application is in heavy industries that rely on complex, multi-motor processes. In metals production, it is found in the main and auxiliary drives of hot and cold rolling mills, where precise speed and torque synchronization between multiple stands is critical for product quality. The module ensures that control commands and feedback from remote I/O units (measuring roll force, speed, temperature) are exchanged without delay or error, maintaining the tight control loops necessary for thin-gauge strip production.
In the mining and minerals sector, drives powering large grinding mills, conveyors, and slurry pumps utilize the ABB SCC-C 23070-0-102321100000 to maintain reliable communication over potentially long distances between the central drive cabinet and sensors/actuators located on the equipment. Similarly, in oil & gas, on compressor trains and large offshore pumps, the module’s robustness ensures control integrity in electrically noisy and safety-critical environments. For marine propulsion and dynamic positioning systems, the deterministic and fault-tolerant nature of this communication link is vital for vessel safety and maneuverability. Essentially, wherever an ACS 800 drive is deployed in a demanding, continuous-process, or high-availability application, the ABB SCC-C 23070-0-102321100000 module is working behind the scenes to guarantee control system cohesion and resilience.
