Each channel accepts ±10 V, ±5 V, ±2.5 V, 0-20 mA, or 4-20 mA — the full set of common process signals for a small control station. The 14-bit resolution means you get 16,384 counts across the selected range, which for a 4-20 mA loop gives roughly 1 µA per count. For a pressure transmitter with a 0-10 bar span, that works out to about 0.6 mbar per count — fine enough for most flow and level loops. ## Active production, stocked item Export control is AL N / ECCN EAR99H, so no special licensing for most destinations. The REACH declaration notes lead content above 0.1% w/w — standard for electronic components with solder terminations. ## Sourcing and compliance The module ships individually, packaged 82 x 34 x 79 mm. Group code R132, product group 4508 — these are Siemens internal classification codes used for catalog sorting and return routing.","metaTitle":"Siemens 6ES7231-4HD50-0XB0 SB 1231 Analog Input, 4 AI 14-bit","metaDescription":"Siemens 6ES7231-4HD50-0XB0 SB 1231 analog input module, 4 AI, 14-bit ADC, ±10V/±5V/±2.5V/0-20mA/4-20mA.
