IS1+ THE REMOTE I/O Expect the best for all hazardous areas

For 30 years, explosion-protected remote I/O systems from R. STAHL have been used for a wide range of process automation applications in Zone 1 and 2 as well as in Division 1 and 2. It is here that they have proven to be the most cost-effective solution with regards to procurement and installation (CAPEX) as well as during operation (OPEX). Thanks to their large range of functions and unique flexibility, remote I/O solutions from R. STAHL are suitable for virtually all tasks relating to process technology. • Savings in field wiring and associated project engineering. • No need to take up space...

SIMPLY THE BEST REMOTE I/O With the intrinsically safe IS1+ Remote I/O, R. STAHL has set standards on which the market has been based up to the present day. • xtension, modification, maintenance – in ongoing E operation in Zone 1 and 2 or Division 1 and 2. • Hot-swappable for all modules and fieldbus interface connections in Zone 1 and 2 or Division 1 and 2. • Extensive protocol support: PROFIBUS DP, Modbus TCP + RTU, PROFINET, EtherNet/IP. • Extended temperature range -40 °C to +75 °C. • Use of cost-effective Ex e GRP or stainless steel field enclosures – no Ex d or Ex p solutions required....
