R.STAHL IS1+ remote I/O system

The IS1+ remote I/O system from R.STAHL allows Ethernet communication in hazardous areas via Profinet, Modbus TCP and EtherNet/IP.

With transmission rates of 100 Mbps, its optical cables are suited to fast, explosion-protected data transmission for Zone 1, as well as utilising inherently safe fibre-optic technology to cross distances of up to 30 km. This type of protection ensures that potentially ignitable optical energy is limited to a non-ignitable level, even under error conditions.

For Zone 2 and distances of up to 100 m, Cat 5 copper cables with ‘EC’ protection can be used. Even in explosive atmospheres, all modules can be exchanged during operations and IS1+ stations can be easily expanded without disconnection.

The available I/O IS1+ modules feature up to 16 channels and are available with intrinsically safe, non-intrinsically safe and pneumatic interfaces as well as being used extensively with most major DCS/PCS/PLC systems. In addition to its Profinet connection and a comprehensive diagnosis function, Stahl IS1+ is suitable for predictive maintenance applications as well as plant asset management system implementation.
