TELI CS3500 Series Technical Notes

The TELI CS3500 series represents a distributed control system (DCS) platform deployed across heavy industrial sectors including petrochemical refineries, chemical processing plants, and power generation facilities. Its modular backplane architecture allows for high-density I/O integration within a standardized rack form factor, making it a long-term infrastructure choice for facilities requiring deterministic process control. The CS3500 platform has been installed in continuous-process environments where system uptime requirements exceed 99.9%, and where module-level replacement — rather than full system overhaul — is the standard maintenance protocol.

CS3500 Full Catalog & Functionalities (SKU List)

The following SKUs represent verified components within the TELI CS3500 series, organized by functional category. Each module is independently replaceable within the CS3500 rack system.
