more about R. STAHL IS1+ remote I/O

Think today about tomorrow
For many years now, IS1 has been the system that is most often installed in explosive atmospheres all over the world. It is continuously improved and expanded by new functions, such as PROFIBUS redundancy, DTM support, integration of optical rings or modules with integrated solenoid valves. In combination with more than 30 years of expertise and know-how in system solutions by R. STAHL, almost every task can be solved.

With IS1 Ethernet, the first step towards the future was taken in 2009 – the first Remote I/O with communication via Industrial Ethernet in Zone 1. PROFIBUS International as well as Fieldbus Foundation™ are currently working on specifications and solutions for the application of their Ethernet protocols PROFINET and FF HSE in connection with Remote I/O – and in both working groups, R. STAHL is actively taking part with prototypes to jointly design the “Future Remote I/O”.

Besides support of modern protocols, a long-lived and flexible I/O level is required as well. Based on experience with thousands of globally installed IS1 systems, R. STAHL now presents the most up-to-date I/O modules with IS1+. The futureproof system solution for complex requirements in hazardous areas of today and tomorrow.

Multifunctional modules allow for a mixture of analogue inputs/outputs, digital inputs/outputs and resistance thermometers/thermocouples

Extended lifetime of up to 15 years with the new low-power technology

Increased temperature range from -40 to +75°C, as well as for extreme environmental conditions

Channel status LEDs for Zone 1 modules for easy commissioning and troubleshooting

Integrated diagnostics, inspired by NAMUR 107, gives warning of failures in due time and also give an optical alarm with a blue LED

Zone 2 installation and Zone 0/1 field devices – even more effective now with the new, cost-saving modules

100% compatibility with the previous modules – easy replacement and upgrading of existing installations
