IS1+ The Remote I/O

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.

CPU & Power modules

The CPU modules for the IS1+ system support the most common communication protocols, such as PROFIBUS DP, PROFINET, Modbus TCP and EtherNet/IP. Copper cables or fiber optic are used for communication, and system redundancy can also be added. The power module provides an intrinsically safe power supply and, like any other module, can be connected and disconnected in hazardous locations.
