Moisture, heat, dust, vapors, chemical fumes, cold, oil, grease, petrol, coolants, lubricants, caustics. All nasty beasties that can lead to micro corrosion that can cause distributed I/O signal corruption, neutral faults or even total failure of the system or plant. In conditions like these, premature device failures and costly repairs are practically a given if you don’t adequately protect your automation system.

Now Siemens has created a whole new line of automation products adapted for harsh environments called SIPLUS extreme. This new product line, which includes modules, CPUs, panels, housings and more, helps to protect your system from environmental hazards. SIPLUS products are suitable for industrial atmospheres in accordance with ISA S71.04 severity level G3, including simultaneous condensation. SIPLUS also meets standard EN 60721, which defines chemical active substances (-3C4), mechanical active substances (-3S4), biological active substances except fauna (-3B2), and determines the maximum pollution concentrations. With protection like this, it’s like putting all your automation equipment in a protective HAZMAT suit!

SIPLUS extreme products hum along under extreme temperature ranges, in contaminated and corrosive atmospheres, and under shock and vibration.
So what is the SIPLUS extreme product line? It's a family of I IA/DT products that have been specially designed and manufactured so these severe operating conditions will not affect performance. Special temperature-resistant components and circuit boards are coated with a conformal coating to make them corrosion resistant. Special mechanical reinforcements are made on the circuit boards so that the components of the SIPLUS solution can withstand vibration and shock.
 
Protection when operating in extended temperature ranges.
Temperature ranges from -40/-25 °C to +60/+70 °C (with medial load) are nowadays no longer uncommon in industry. Decentralized plant layouts have meant more and more equipment is in unheated or unprotected locales. SIPLUS extreme modules have been developed for use in this wide range of ambient temperatures. And, this means both cold start and continuous operation. This delivers a number of advantages to you:

• Enhanced reliability due to use of higher quality components
• Most products don’t require derating
• Cost reduction, as no cooling and heating equipment is necessary
• Reduced maintenance and service
• Inclusive protection during medial load and condensation

Protection when operating in corrosive atmospheres.
Extreme air pollution is common in chemical processing industry. Chlorous and sulphurous atmospheres are common in the paper recycling and sewage treatment industries. The conformal coating in SIPLUS extreme products means these harmful gases won’t have a chance at starting micro corrosion that can bring your system down.

Protection when operating in vibration and dirty, wet conditions.
Dust, dirt, high pressure water, steam, oil and lubricants easily work together to eat away at non-protected wiring, coatings, circuit boards, finishes, connectors and switches. Add vibration to this situation and you quickly accelerate the friction, grinding, grating and seepage that can chew away at components. And we all know when these units will go down…at the worst possible moment! Save the stress, downtime and expensive repairs by choosing SIPLUS. For example, Siemens ruggedized positioning motors are resistant to oil, grease, salt, water, alcohol, glycols, aliphatic and aromatic compounds. This makes them the perfect choice for process, machine tool, chemical or food applications.

Even panels and housings are practically hermetically sealed!
The SIPLUS line doesn’t stop at protecting the electronics. Control panels are encapsulated as well. This eliminates costly ventilation systems when operating in areas with high air contamination, such as sand, dust and sulfur. You’ll see improved operational reliability under the harshest conditions.

Where should you use SIPLUS extreme?
SIPLUS extreme should be used everywhere you need to protect your systems from environmental hazards, such as Oil & Gas, Water & Wastewater, Pulp & Paper, Metals & Mining, Transportation, Chemicals, Cement & Glass and the Shipbuilding industry. How can your application benefit from SIPLUS extreme?
