6ES7531-7NF10-0AB0 New Original Siemens S7-1500 Plc Programming Controller module

2. Key Selling Points

1. High-Performance Analog Input Module for S7-1500 Series: Model AI 8xU/I/RTD/TC ST, a multifunctional analog input module in the SIMATIC S7-1500 PLC system—supports voltage, current, RTD, and thermocouple signals, ideal for complex process control applications.

2. High Accuracy & Resolution: Uses 16-bit A/D conversion with effective resolution up to 15 bits + sign, and basic accuracy as low as ±0.3%, ensuring precise and stable signal acquisition.

3. Direct Temperature Measurement Support: Connects RTDs (Pt100/Pt1000) and thermocouples directly without external transmitters—enabling high-precision temperature measurement while saving cost and panel space.

4. Per-Channel Configuration: Each channel can be individually set for signal type, range, filter frequency, and temperature unit (°C/°F)—offering maximum flexibility for diverse sensors and processes.

5. Galvanic Isolation: All analog input channels are electrically isolated from the backplane bus—reducing noise interference and enhancing system stability in industrial environments.
