6ES7231-5QA30-0XB0 New Original Siemens S7-1200 Plc Programming Controller module

2. Key Selling Points

1. 4-Channel Analog Input – Meets Multi-Signal Acquisition Needs:Provides 4 independent analog input channels, capable of simultaneously acquiring continuous field signals such as temperature, pressure, flow, and level.

2. Supports Multiple Voltage & Current Signals – High Compatibility:Each channel can be configured for ±10V, 0–10V, ±20mA, 0–20mA, or 4–20mA inputs, compatible with various transmitters (e.g., PT100, pressure sensors, flow meters).

3. High Resolution – Ensures Measurement Accuracy:Offers 12-bit resolution for voltage and 11-bit + sign bit for current, enabling precise detection of small signal changes and improved control accuracy.

4. Plug-and-Play Installation – Easy Setup:Mounts directly to the right of the CPU, powered via backplane bus, no external power required. DIN-rail mounted with screw terminals for reliable installation.

5. Software Filtering Function – Enhances Signal Stability:Supports digital filtering settings (e.g., sampling count, averaging) in STEP 7-Micro/WIN SMART software, effectively suppressing noise and improving signal reliability.
