Analog Input Expansion Module for S7-200 SMART:Model AI08, an 8-channel analog input module in the SIMATIC S7-200 SMART series—designed to acquire standard analog signals from field sensors or instruments for precise monitoring of continuous process variables such as temperature, pressure, flow, and level.
High Accuracy & Resolution:Features a 12-bit A/D converter (resolution 1/4096), ensuring precise signal acquisition.Basic measurement error less than ±0.5%—suitable for high-precision process control applications.
Supports Open-Circuit & Range Error Diagnosis:Supports open-circuit (wire break) detection in current input mode.Detects out-of-range conditions (e.g., 0 mA or 22 mA)—diagnostic data can be accessed via STEP 7-Micro/WIN SMART software for remote troubleshooting.
Seamless Integration with STEP 7-Micro/WIN SMART:Automatically recognized in STEP 7-Micro/WIN SMART software—supports graphical hardware configuration, symbolic addressing, online monitoring, and parameterization—greatly improving engineering efficiency and system maintainability.
Powered via Backplane (No External Power Required):Receives operating power (5 V DC) from the CPU through the backplane bus—no external power supply needed, simplifying installation and reducing cabinet space.
