6ES7231-4HF32-0XB0 New Original Siemens S7-1200 Plc Programming Controller module

2. Key Selling Points

1. 4-Channel Analog Input – Meets Basic Signal Acquisition Needs:Provides 4 analog input channels for monitoring continuous signals like temperature, pressure, level, and flow—ideal for small process control systems.

2. Voltage & Current Input Support – High Compatibility:Each channel can be configured via DIP switch for either ±10 V voltage input or 0/4–20 mA current input, compatible with various transmitters and sensors.

3. 12-Bit High Resolution – Accurate Data Acquisition:Offers 12-bit resolution (unipolar), ensuring precise analog-to-digital conversion with a minimum resolution of 2.5 mV (voltage) or 5 μA (current).

4. Optical Isolation – Strong Noise Immunity:Features galvanic isolation between field side and CPU, effectively suppressing electrical noise and enhancing system reliability.

5. DIP Switch Configuration – Simple & Intuitive Setup:Input type (voltage or current) for each channel is set via DIP switches, eliminating the need for software configuration and simplifying commissioning.
