IS1+ is extremely simple to use: A CPU & Power Module and
several input/output modules are snapped on to the BusRail (35 mm
DIN rail). The unique power supply concept, developed especially
for use in hazardous areas, makes system planning as simple as
for normal industrial I/O systems. Plug & play without separate
engineering tools.
A4
IS1+ is particularly flexible: Suitable for small and big signal
quantities with field stations installed in safe or explosive
atmospheres. An intrinsically safe fieldbus using copper-wire or
fibre-optic technology connects field stations in Zone 1 / Division 1
with the automation devices. The system is completely HART
transparent.

IS1+ is extremely economical: Modules with 8 or 16 inputs lower the
price per signal. DTM technology is used for full integration into
standard Asset Management and Engineering systems allowing
easy and fast commissioning, trouble shooting and maintenance.
