The AC 31 control system is built on a modular architecture, offering both high programmability and flexible adaptability. The Model 90 in this series serves as the core product and is particularly suited for distributed control system architectures.
▌Extensive Application Compatibility
The system covers applications ranging from 14 to over 1000 I/O points. It is suitable for small equipment with basic automation functions and can also be expanded to large facilities spanning hundreds of meters or even kilometers. With a unified component system, AC 31 provides solutions for applications of various scales, including distributed control in workshops, plant areas, or entire machines.
▌Efficient Wiring Solution
In modern control systems, the increasing number of external devices such as contactors, relays, circuit breakers, sensors, push buttons, and intelligent preprocessing units has significantly raised wiring complexity. The AC 31 system uses a single twisted pair for global communication, reducing control cable usage by up to 80%, effectively simplifying installation and improving reliability.
▌Comprehensive Diagnostic Capabilities
The system offers full diagnostic functionality, enabling accurate detection, localization, and display of abnormalities in input and output signals, such as discontinuities, overloads, or short circuits. Meanwhile, the status of the CPU and system bus is continuously monitored to ensure stable operation.
▌Significant Cost Efficiency
AC 31 not only achieves savings in wiring but also substantially reduces labor and material costs during system planning and installation, delivering notable time and economic benefits to users.
▌Flexible Expansion and Adjustment
The Series 90 modules feature plug-and-play connectors, allowing users to replace modules directly without rewiring, greatly facilitating system modification and expansion.
Note: This product series was formerly named ABB Procontic CS31.
