Product Function

Voting Unit: The ABB DSSS171 is primarily a voting unit. In this case, it is used to vote on the 24V DC power supply in a system with redundant power supplies to ensure power distribution reliability. Doing so helps avoid power failure conditions and optimally select the most stable and reliable power supply for maximum system uptime.

Signal Conditioning and Conversion: The ABB DSSS171 completes basic signal conditioning operations, including input signal filtering, amplification, and isolation. This not only protects the internal wiring from errors that may be caused by electrical noise or interference, but also improves the signal for better processing. For the reasons mentioned above, it also converts the analog signal to a digital format within the system for further processing and manipulation, and performs the same operations when converting the output signal.

Excellent system integration: This easy-to-integrate ABB DSSS171 is compatible with larger control systems, such as ABB's Advant master process control system. This allows smooth communication with other components via common communication interfaces, facilitating seamless information exchange and synchronization. This makes it possible to build complex and comprehensive control strategies to suit a variety of industrial processes and requirements.

Applications

Industrial Automation: The ABB DSSS171 is used in different industries such as manufacturing, chemicals, oil and gas, and power generation. The use of automated systems can reduce labor costs while increasing productivity; for example, in manufacturing plants, it can be integrated into production line control systems to ensure smooth operation of machines and equipment. In the chemical and oil and gas industries, it helps to supervise and manage important processes, including temperature, pressure and flow, for safety and efficiency3.

Process Control: Best suited for applications that require precise control of process variables. For example, in pharmaceutical processes, it can be used to accurately control temperature and pressure in reactors, helping to ensure the quality and consistency of the final product. In processing plants, it can control chemical flows and track quality parameters in raw material, intermediate and final product flows.

Power Distribution and Management: Its redundant power distribution capabilities make it a critical part of the power distribution system when reliability is critical. Equipment in data centers, telecommunications facilities, and other critical infrastructure applications enables uninterruptible power supply and protects sensitive equipment from power failures.
