It accepts voltage signals (±10 V) and current signals (0–20 mA \/ 4–20 mA) with 14‑bit or 16‑bit resolution depending on signal type and an accuracy of ±0.1%. Powered by 24 V DC and communicating on the S7-1200 backplane bus, it mounts on a DIN rail and offers IP20 protection. Diagnostic features include channel diagnostics and status indicators, and the operating temperature range is -20°C to +60°C. It is commonly used for system expansion, replacement, and precise analog signal acquisition of parameters such as temperature, pressure, and flow in industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":50558456529198,"sku":"New","price":410.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/6ES7_231-4HD32-0XB0.webp?v=1751530009","url":"https:\/\/plgautomation.com\/products\/siemens-6es7-231-4hd32-0xb0-analog-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
