SIMATIC S7-1200SB 1231 Single-Channel Analog Input Board
1 AI · VOLTAGE OR CURRENT · DIFFERENTIAL 12-BIT INPUT
Siemens 6ES7231-4HA30-0XB0 SIMATIC S7-1200 SB 1231 Analog Input Board
A single-channel differential analog input signal board for voltage or current measurement at the S7-1200 CPU front.
PRODUCT CONTEXT
Product Profile
6ES7231-4HA30-0XB0 is the SB 1231 analog input signal board for SIMATIC S7-1200. It converts one differential voltage or current signal into a controller process value without adding a separate signal module.
Current measurement uses the documented terminal link between R and 0+, while voltage measurement follows a different input path. The chosen mode, sensor supply, polarity, shielding and scaling must remain in the channel record.

CUSTOMER QUESTIONS
FAQ
Q01
What should accompany a 6ES7231-4HA30-0XB0 enquiry?
Provide the CPU article number, complete board label, signal type, sensor supply, range, terminal map and quantity.
Q02
Can 6ES7231-4HA30-0XB0 measure an RTD or thermocouple directly?
No. Use the specified S7-1200 temperature-input board when those sensor types are required.
Q03
Why is the R-to-0+ link important for 6ES7231-4HA30-0XB0 current input?
It is part of the documented current-input terminal arrangement; omitting or misplacing it changes the measurement path.
Q04
What channel evidence should be retained before replacing 6ES7231-4HA30-0XB0?
Save scaling, filter, diagnostic state, polarity, conductor markers and stable reference readings.
Q05
What closes 6ES7231-4HA30-0XB0 commissioning?
Retain multi-point signal results, correct engineering scaling, stable diagnostics and completed process-response tests.
