The TRICONEX 3704E analog input module features 64 general-purpose input channels, a 75ms update rate, 12-bit resolution, and an accuracy of 0.25% of the FSR (0-60℃). It employs a triple redundancy (TMR) design, with three independent CPUs operating in parallel, supporting hot-swapping. A single point of failure does not affect system safety, resulting in an extremely long mean time between failures (MTBF). Specifically designed for industrial automation and safety instrumented systems (SIS), it supports a triple modular redundancy (TMR) architecture and meets SIL3 safety standards. Primarily used for acquiring analog signals such as temperature, pressure, and flow rate and converting them to digital signals, it is widely applied in high-risk industries such as petrochemicals, power, and nuclear energy.
