R. STAHL presents IS1+ − the future remote I/O system

Multi-functional, more diagnostics options, increased availability:

Introducing IS1+, a key innovation for the leading explosion-protected remote I/O system IS1. IS1+ now provides various additional features to address current and future requirements.

In recent years, IS1 has maintained technology leadership in hazardous areas through many innovative new functions, including Fast Ethernet connection, PROFIBUS redundancy, DTM support, integration of optical rings and modules with integrated magnetic valves. While it surpasses these features already at its market introduction, IS1+ also places high priority on protecting previous investments in existing plants and machinery. The new I/O modules are fully backward compatible to their predecessors, allowing users to exchange or upgrade legacy devices without any changes to project planning and wiring.

New mixed modules enable efficient solutions even at a low signal density and reduce the number of module types by 50%, which minimises expenses for spare parts storage. The IS1+ module range includes an eight channel analog I/O module with HART, a 16 channel digital I/O module and an eight channel temperature module for resistance thermometers and thermocouples. The signals can be individually parameterised for each channel.
