Remote I/O system for mixed operations
Remote I/O system allows for a comfortable hot swap of all system components, including CPU and supply unit
R Stahl offers I/O modules specially designed for signals from hazardous areas zones 1 and 2 and from safe areas, thereby optimising its remote I/O system IS1 for mixed operation For example, this allows Ex nA and non-Ex signals as well as Ex nL signals to be connected to a module approved for zone 2

Isolators designed for intrinsically safe circuits
An innovative and future-leading series of modules for intrinsically safe circuits, an isolator series has two input channels; all standard analogue and digital signals are accommodated.
A mix of intrinsically safe and non-intrinsically safe signals can also be handled just as easily: I/O components for zone 1 and 2 signals can be installed on one bus rail.
Using a separating plate between intrinsically safe and non-intrinsically safe signals ensures the required 50 mm separation.
R Stahl's wide range of modules thus enables the design of customised, cost-efficient IS1 installations spanning different areas of a plant.
The module program for zone 2 includes analog HART input, analog HART output, digital NAMUR input, digital voltage input and digital relay output models.
The remote I/O system, which has been a market leader for zone 1/21 for a long time, also shows its strengths in zone 2: IS1 allows for a comfortable hot swap of all system components, including CPU and supply unit, in zones 1 and 2.
It also provides an efficient Profibus DP connection via copper cables or optical fibre and can be designed with full or line redundancy.
