AUTOMATICALLY THE BEST SOLUTION:
IS1+ REMOTE I/O

REMOTE I/O SYSTEMS feature IMPRESSIVE FLEXIBILITY

The complexity of machines and advanced systems have increased. Sub-processes need to be seemingly integrated. Rapid and reliable transmission of signals and data is essential. In this evolving market, R. STAHL provides sophisticated technology for automation applications in explosive atmospheres: E.g. Zone 1 and Zone 2 remote I/O systems. These are highly modular and versatile. The adaptable system integrates to the users needs. Many modules with intrinsically and non-intrinsically I/O are available to fit all needs. Suitable for incredibly demanding applications and harsh environments. Process data, like temperatures, flow and levels, are consistently and quickly transmitted from Zone 1 or Zone 2 to control systems. Remote I/O systems can also efficiently operate actuators, such as solenoid valves and positioners in hazardous areas.

Explosion protected Remote I/O systems from R. STAHL are suitable for diverse functions and the harshest of industrial environments. They are a preferred solution for virtually all tasks in the process industry. This linked graphic of built-in features illustrates the advantages of remote I/O technology installed in hazardous areas for control compared to conventional "point to point" installations.

No bulky switch and distributor cabinets in the control room.
Savings in material and working time for field wiring.
Extensive functions for simplifying commissioning on-site and remotely.
Integrated diagnostics provide an early warning of failures and avoid system downtimes.
Fully compatible with conventional and HART-enabled field devices and hardware.
Extensive network capabilities, including ethernet and fieldbus.
Variety of modules for versatility.

For procurement and installation (CAPEX) and operation (OPEX) there is no more cost-effective solution.

The benchmark in process automation: IS1+ Remote I/O

Continuous development ensures that the Remote I/O System IS1+ is, and remains, the market leading solution. International certificates for explosion protection and ship building is a statement of confidence. The IS1+ System is used over the world in Zone 1, Zone 2, Division 1, and Division 2 areas.

Other advantages of the IS1+ include:

Typically 25% cost savings compared to conventional installations.
Easier installation, quicker commissioning and shorter maintenance times.
Can be used in extreme environments of -40 °C to +75 °C and are thus also suitable for offshore systems and LNG tankers.
Long service life of at least 15 years even under harsh environmental conditions.
Detailed diagnostics ensure safe operation and enable predictive maintenance.
Energy savings of up to 40% compared to conventional installations.
Can be combined with other products and technologies regardless of the manufacturer and process control system or controllers.
Flexible and easy to use in virtually any automation system or network.

IS1+ is thus the ideal solution for your automation tasks and control coordinator in the process industry.

IS1+ REMOTE I/O SYSTEM IS AN EXCEPTIONAL MULTI-PROTOCOL SOLUTION

The IS1+ Remote I/O System contains support for Ethernet-based network communication protocols and connectivity (PROFINET, Modbus TCP, EtherNet/IP but also PROFIBUS DP and Modbus RTU). For each, HART transmission and FDT/DTM support is, naturally, included. The required protocols can be easily set up by the users themselves. Storage is then reduced for industrial applications with different automation systems. This multi-protocol functionality allows for flexible migration and thus simplifies modernisation.

Ideal for extending or building installations, the IS1+ Remote I/O Systems is suitable for control and applications in hazardous areas or harsh industrial environments. R. STAHL's IS1+ is found throughout the world in the petrochemical, pharmaceutical, machine building, food & beverage and oil & gas industries. It is also perfect for areas where space is constrained and weight matters, such as on FPSO and LNG tankers. Many I/O-modules allow the system to adapt for different environments and situations.

THE BENEFIT FOR YOU: IS1+ COMPONENTS

The IS1+ Remote I/O System offers a large selection of components and modules for a range of purposes in automation and process control systems. Multi-functional modules are available with analog or digital inputs/outputs and for all temperature sensors. Additionally, field enclosures, FO Switches, and Device Type Managers (DTM) and power supplies can be provided for specific automation tasks.
