Product Performance

AI3351S2 adopts a triple modular redundant signal acquisition circuit and 24-bit high-precision A/D converter, with measurement error ≤0.1% over the full temperature range, ensuring accuracy and reliability of process parameter acquisition. Independent isolation design for each channel combined with differential input structure provides common mode rejection ratio ≥120dB, effectively resisting strong electromagnetic interference and ground loops in industrial sites.

Integrated with comprehensive self-diagnosis functions, it can real-time detect channel open circuit, short circuit, sensor faults and module power abnormalities, with fault diagnosis coverage ≥99.9% and fault response time ≤1ms, feeding back fault status via LED indicators (red-green dual-color per channel) and system bus. Supports online calibration and configuration, enabling parameter adjustment without module disassembly.

Seamlessly compatible with Tricon CX series controllers, data transmission delay ≤5ms, meeting the real-time requirements of safety interlocks, with mean time between failures (MTBF) ≥300,000 hours, complying with SIL 3 safety integrity level requirements.
