Siemens’ Industry Automation Division announced it has expanded the range of applications of its Siplus extreme control and communication products that are particularly suited to harsh environmental conditions. The devices are now also certified for use in toxic atmospheres according to ISA-S71.04 GX, for salt mist and dense dust.

The components were previously suitable for use in corrosive atmospheres according to ISA-S71.04 G1, G2 and G3 as well as in situations involving 100% humidity, dewing and ice formation. The Siplus extreme devices are for use in aggressive environmental conditions that would not be suitable for standard Simatic automation components.
