Description: Switch cabinets form part of installation engineering with impact on the total costs of machines and systems. Connecting single wires in switch cabinets places totally different demands on the connectivity of I/O components than applications in terminal boxes. Advanced field bus I/O station with a modular installation and removal system for use in switch cabinets is specially designed to cater to the basic requirements of modern switch-cabinet wiring. A number of different bus nodes for conventional field bus protocols and a wide range of I/O modules are the key to a large number of cost-effective solutions for processing analog and digital signals. The modules are quick and simple to install directly on the mounting rail without any tools. The bus nodes are expandable with any variety of I/O modules up to a total number of eight modules. The slim design and its high package density of 16, or even 32 I/O channels per module result in optimised space utilisation on the mounting rails. I/O signals are connected by means of spring-loaded terminals making the first-time installation very simple and time saving. The terminals are maintenance-free and assure reliable, durable, and safe connections. All modules are equipped with a continuous diagnostic system as standard. The status displays are easily assignable due to the transparent connecting terminals. This is a significant contributory factor to reducing unscheduled outages and plays a vital role in raising productivity.
