ODOT CT Series Technical Notes

The ODOT CT Series represents a standardized family of distributed I/O modules engineered for deployment in heavy industrial environments including chemical processing plants, petroleum refineries, power generation facilities, and water treatment infrastructure. Built around a compact DIN-rail form factor with a proprietary backplane bus architecture, CT Series modules are designed for deterministic real-time data acquisition and control output. The series has achieved significant installed base across Asia-Pacific industrial automation projects, particularly in process industries requiring IEC 61131-3 compliant control architectures. CT Series modules interface natively with ODOT's CM Series communication adapters and are compatible with major PLC platforms via EtherNet/IP, PROFIBUS-DP, and Modbus TCP gateways.
