Product Overview
The ABB CS31 is a pivotal component within ABB’s industrial automation portfolio, designed to revolutionize control and monitoring in diverse industrial settings. As a distributed automation system, the CS31 is engineered to handle complex tasks with high precision and reliability. It serves as an ideal solution for applications where modularity and cost – effectiveness are crucial factors.
This system features a central unit, housed in a compact enclosure that can be either screw – mounted or attached to a DIN rail, ensuring flexible installation options. It is complemented by easily detachable remote input/output (I/O) plug – in units, which are equally adaptable with screw or DIN rail mounting on their plug – in bases. The connection between the central unit and I/O units is established through a simple RS 485 – based twisted – pair arrangement, facilitating seamless data transfer. The ABB CS31 offers a host of features such as a decentralized architecture, which not only reduces wiring costs (in terms of design, materials, and commissioning time) but also enables a high degree of configurability of I/O units. With extensive diagnostic capabilities and a freely expandable network that can be connected during device operation, it ensures smooth operation and easy system growth. Additionally, its simple and transparent programming model allows all remote I/O channels to be treated as if they were being processed centrally, streamlining the control process.
