ICS Triplex legacy product support

Whether you’re looking to maintain your system or planning to upgrade or modernize – we can help you keep your system functioning at its best.

Future-proofing your legacy systems

Process safety systems play an integral part in your plant. Regularly maintaining or upgrading legacy systems is key for optimizing the performance of your assets and the safety integrity of your system. At Sensia, we can support your ICS Triplex® legacy systems in many ways, including: spare parts, phone support, field support, product repairs, system modifications, upgrades and more. Plus, we can also help you upgrade or modernize in line with your business goals.

Support and maintenance

Upgrade options are available on most ICS Triplex legacy process safety systems – enabling customers to replace the processors only. This approach retains the installed I/O and field wiring, with the option to upgrade to meet operational requirements later. This valuable option offers enhanced capabilities, minimal downtime, and can be executed with the existing systems live in some cases.

For customers of the Plantguard systems and modules, we have a direct, factory-set replacement. Simply install the Alternative Trusted® Modules as you would a regular spare replacement. In doing this, you maintain full product support.

In addition, we can provide a range of support services, including: technical, product, and system support, product repairs, routine and special maintenance, system modifications, extensions, and upgrades.


A system upgrade can be simple when the originally installed legacy I/O and field installations are
retained. When you plan and prepare effectively, an upgrade can be done in a few hours instead of weeks or months.
