3. Key Features
3.1 Integrated I/O & Control Capability
Combining 16 DI, 8 DO, and 4 AI channels in a single module, the DC-TAIL51 eliminates the need for separate I/O and control units, simplifying system architecture. With support for up to 1000 ladder logic rungs, it executes complex discrete control tasks like sequential valve operations and interlock protection without additional controllers.
3.2 SIL 2 Safety Compliance
Certified for SIL 2 operation, the module integrates built-in fault detection (FDT) and self-diagnostic functions, ensuring ≥99.5% fault coverage. It supports redundant power input and communication paths, preventing system failures in safety-critical applications like chemical reactor temperature control and emergency shutdown systems.
3.3 Fast Response & Real-Time Control
With a discrete I/O response time of ≤10 ms and analog I/O response time of ≤50 ms, the module ensures real-time monitoring and control of process variables. This fast response enables rapid intervention in abnormal process conditions, reducing the risk of production accidents and quality deviations.
3.4 Robust Anti-Interference Performance
Featuring high-voltage galvanic isolation (1000 V DC channel-to-ground) and enhanced EMC performance, the module resists interference from industrial electrical noise, voltage surges, and radio frequency signals. Its rugged design ensures stable operation in harsh petrochemical and oil & gas environments with heavy electrical equipment.
