IS1 remote I/O - 9224 IS1remote I/O

the market leader in Zone1,Division 1

R.STAHL has already marketed the second generation of an explosion protected Remote I/O System: the IS1.It features a simple structure, unique flexibility and tremendous efficiency and economy, and these aspects make it the most popular Remote I/O System for Zone 1 and Division 1. Any requirement can be met flexibly with IS1, regardless of whether the application requires only a few signals or very many signals or whether it necessitates installation in Zone 1, Zone 2, Division 1 and Division 2 or in the control room. The intrinsical- ly safe system structure with Ex i fieldbus, using either copper wires or fibre-optic cables, allows the system to be serviced and repaired even in hazardous areas. The system may be provided with a redundant structure if availability requirements are stringent. Many additions and enhancements have made R.STAHL’s Remote I/O IS1 even better and more effective in recent years. These add-ons have also optimised the sys- tem for mixed operation of Zone 1/Zone 2, Division 1/Division 2 and non-Ex signals. The intrinsically safe Profibus DP fieldbus interface is now also available in accordance with Profibus Standard RS 485-IS, and an automatic baud rate detection and repeater function has been introduced with the new Fieldbus Isolating Repeater. This provides line redundancy as a second redundancy option. HART integration has also been adapted optimally to various automation systems. The IS1 System has been classified SIL 1 for safety- related applications in accordance with IEC 61508 and a Plant Stop function has been integrated for SIL 2. All international approvals allow worldwide use. IS1 from R.STAHL – the simplest, technically perfect, efficient and economic solution. The easy way.
