6ES7231-5PF32-0XB0 New Original Siemens S7-1200 Plc Programming Controller module

2. Key Selling Points

1. 4-Channel RTD Input + 2-Channel Analog Output (AI/AQ):Integrates 4 RTD (Resistance Temperature Detector) inputs and 2 analog outputs (AQ), specifically designed for temperature monitoring and closed-loop control in heating, cooling, and thermal regulation applications.

2. Supports Multiple RTD Sensor Types:Input channels support common RTD sensors including Pt100, Pt1000, Ni100, Ni1000, allowing direct connection to industrial temperature probes—no external transmitter required.

3. High-Accuracy Temperature Measurement:Offers 15-bit effective resolution (including sign bit), with high measurement accuracy and typical error < ±0.3°C (sensor-dependent), suitable for precision temperature control.

4. 2 Analog Voltage/Current Outputs:Outputs support ±10 V voltage and 0–20 mA / 4–20 mA current signals, configurable to drive control elements such as control valves, actuators, or frequency references for drives.

5. Isochronous Mode Support:Enables microsecond-level time-synchronized sampling and output, ideal for multi-loop PID control and applications requiring strict timing consistency.
