Functional Features

• Signal Conversion: Can convert analog signals from field devices, such as temperature, pressure, and flow signals, into digital signals, which are transmitted to the control system to realize process monitoring and control.
• High Reliability: Adopts Triple Modular Redundancy (TMR) design to improve system availability and reliability, ensuring normal operation even in case of faults.
• Strong Anti-Interference Ability: Differential input design can reduce the impact of common-mode noise; meanwhile, it has low noise characteristics, which can minimize the impact of electrical noise on measurements.
• High Configurability: Supports multiple input types and configuration options; parameters such as input range, resolution, and sampling rate can be configured to meet different application requirements.
• Hot-Swap Function: Supports hot swapping, allowing online replacement of faulty modules without shutting down the system, facilitating maintenance.
