SIPLUS extreme protects automation systems from environmental hazards

Moisture, heat, dust, vapours, chemical fumes, cold, oil, grease, petrol, coolants, lubricants, caustics. These are all problems facing system operators that can lead to micro corrosion and cause distributed I/O signal corruption, neutral faults or even total failure of the system or plant. In such conditions premature device failures and costly repairs can be a regular occurrence if an automation system isn’t adequately protected.



Siemens Industry Automation has developed a new line of automation products adapted for harsh environments called SIPLUS extreme. This new product line, which includes modules, CPUs, panels, housings helps to protect systems from commonly found environmental hazards.



SIPLUS products are suitable for industrial atmospheres in accordance with ISA S71.04 severity level GX, 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. SIPLUS extreme products hum along under extreme temperature ranges, in contaminated and corrosive atmospheres, and under shock and vibration.



The SIPLUS extreme product family has been specially designed and manufactured so that 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. In addition, mechanical reinforcements are made on the circuit boards so that components of the SIPLUS solution can withstand more extreme 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 frequently seen in industry. Decentralised 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 with a number of operational efficiency advantages:



• 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 now commonplace in chemical processing industry. Chlorous and sulphurous atmospheres are seen in the paper recycling and sewage treatment industries. The conformal coating in SIPLUS extreme products means that harmful gases won’t have a chance at starting micro corrosion that attack systems.



Protection when operating in vibration and dirty, wet conditions.



Dust, dirt, high pressure water, steam, oil and lubricants often work together to eat away at non-protected wiring, coatings, circuit boards, finishes, connectors and switches. Add vibration to this situation and it can accelerate the friction, grinding, grating and seepage that effect components performance. The Siemens ruggedized positioning motors are resistant to oil, grease, salt, water, alcohol, glycols, aliphatic and aromatic compounds. This makes them an ideal choice for process, machine tool, chemical or food applications.



Control panels are encapsulated as well. This eliminates costly ventilation systems when operating in areas with high air contamination, such as sand, dust and sulphur delivering improved operational reliability under the harshest conditions..



The SIPLUS extreme range offers users a number of benefits, including:



.



• High security of investment due to industry-specific modified standard products



• Higher productivity due to minimized downtimes



• Energy-saving and maintenance-free operation, as no air-conditioning or heating is necessary



• Integrated automation on the basis of TIA (Total Integrated Automation) for the implementation of customer specific solutions



• Familiar configuration and tools



• Standard documentation and software (Mall, CA01, Internet)



• Retention of familiar sales channels



• Based on innovative Siemens standard products



• Long-term availability assured, even for spare parts



• Full warranty of SIPLUS extreme products, identical to Siemens standard products
