basic components (Figures 1 and 2). 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 or in the control room. The intrinsically 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. Multi-channel modules and convenient commissioning and servicing tools mean that IS1 from R. STAHL is the perfectly economical solution. The international approvals allow use of the system worldwide.
