Triconex DI3301 Key Features
Triple Signal Processing Architecture
The Triconex DI3301 utilizes independent three-channel signal conditioning circuitry and a patented "2oo3" voting mechanism to eliminate false signals, resulting in 10 times greater reliability than traditional DI modules.
Dynamic Self-Test Technology
The module features a built-in periodic pulse test function that verifies input circuit integrity without interrupting the process, achieving a diagnostic coverage rate of 99%, far exceeding the industry average.
Environmental Tolerance
Validated by cold start tests at -40°C and full-load operation at 70°C, it is particularly well-suited for the extreme operating conditions found in Middle Eastern desert oil fields and oil and gas fields within the Arctic Circle.
