6ES7331-7NF00-0AB0 New Original Siemens S7-300 Plc Programming Controller module

2. Key Selling Points

1. 8-Channel Multifunction Analog Input – Highly Integrated:Supports voltage, current, thermocouples (TC), and RTD inputs in one module, enabling simultaneous acquisition of diverse field signals (e.g., temperature, pressure, flow), reducing module variety and saving rack space.

2. High Resolution & Accuracy:Resolution up to 15-bit plus sign (16-bit), with basic accuracy as low as ±0.3%, ensuring precise measurement for demanding process control applications.

3. Individually Configurable Per Channel:Each of the 8 channels can be independently set to voltage, current, or temperature input, supporting standard RTDs (Pt100, Ni100, Cu10) and thermocouples (J, K, T, E, R, S, B, L, U, N).

4. Built-in Cold Junction Compensation (CJC) for Accurate TC Measurement:Automatically compensates ambient temperature effects on thermocouple readings, ensuring high measurement accuracy.

5. Supports 2-, 3-, and 4-Wire RTD Connections:Allows selection of wiring mode to eliminate lead resistance errors; 4-wire connection enables highest accuracy in temperature measurement.
