AI815 3BSE052604R1 Analog input module
The AI815 3BSE052604R1 is an analog input module produced by ABB. ABB’s AC 800M series process control systems feature eight separate analog input channels that receive and convert analog signals (such as current or voltage signals) from field sensors to digital signals for easy processing and analysis in the control system.
In addition, the module also supports a variety of signal types, such as 0-20 mA, 4-20 mA, 0-10V and 0-5V, with high-precision analog signal conversion capabilities and electrical isolation between channels, improving system reliability and safety.
AI815 3BSE052604R1 is mainly used in industrial automation systems. As an analog input module produced by ABB, it is able to receive and convert analog signals (such as voltage, current, temperature, etc.) from field sensors to digital signals for processing and monitoring by computers or control systems. Therefore, it has a wide range of applications in industrial automation, power system monitoring, and various occasions requiring current measurement.
