- +/-10 V DC
- 12 bit
It converts one analog voltage or current signal into a digital value for a compatible S7-1200 CPU without adding a separate side-mounted module. It is used with a correctly configured TIA Portal channel, suitable transducer or signal conditioner, and shielded analog wiring in compact measurement, machine monitoring, and process-control applications.
Important Notice: Use the complete 6ES7231-4HA30-0XB0 code and verify the physical nameplate, project, accessories, and current Siemens documentation before installation or replacement.

Read and follow the exact Siemens documentation and host-equipment instructions before use. Verify 6ES7231-4HA30-0XB0 from the physical nameplate.
1
CPU support: Verify the exact S7-1200 CPU and signal-board slot compatibility
2
Input mode: Configure either +/-10 V or 0 to 20 mA before connecting the signal
3
Wiring: Check polarity, reference potential, shield termination, and loop supply
4
Protection: Keep the applied voltage or current within the Siemens channel limits
5
Commissioning: Validate raw value, engineering scaling, noise, open-circuit response, and alarms
