Inputs resolve at up to 14 bit across ±10 V, ±5 V, ±2.5 V, 0-20 mA or 4-20 mA ranges; outputs cover ±10 V, 0-20 mA and 4-20 mA at up to 14 bit resolution. It runs from 24 V DC and reports wire-break and short-circuit diagnostics.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e6ES7233-4HF50-0XB0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSIMATIC S7-1200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type Designation\u003c\/td\u003e\n\u003ctd\u003eSM 1233, AI 4x14 bit\/AQ 4x14 bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC (20.4-28.8 V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Inputs\u003c\/td\u003e\n\u003ctd\u003e4, current or voltage differential\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Ranges\u003c\/td\u003e\n\u003ctd\u003e±10 V, ±5 V, ±2.5 V, 0-20 mA, 4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resolution\u003c\/td\u003e\n\u003ctd\u003eup to 14 bit (13 bit + sign)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd\u003e4, voltage or current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Ranges\u003c\/td\u003e\n\u003ctd\u003e±10 V, 0-20 mA, 4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Resolution\u003c\/td\u003e\n\u003ctd\u003e14 bit (voltage), 13 bit (current)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad Impedance, Voltage Out (min)\u003c\/td\u003e\n\u003ctd\u003e1000 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad Impedance, Current Out (max)\u003c\/td\u003e\n\u003ctd\u003e600 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCycle Time (all channels)\u003c\/td\u003e\n\u003ctd\u003e0.625 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Loss\u003c\/td\u003e\n\u003ctd\u003e4.7 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDegree of Protection\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmbient Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to 40°C (up to 60°C horizontal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e30 x 125 x 100 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e174 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCE\u003c\/li\u003e\n\u003cli\u003eUL\u003c\/li\u003e\n\u003cli\u003ecULus\u003c\/li\u003e\n\u003cli\u003eRCM\u003c\/li\u003e\n\u003cli\u003eKC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe 6ES7233-4HF50-0XB0 combines 4 inputs and 4 outputs on one 30 mm module, which saves backplane slots compared to running separate SM 1231 AI and SM 1232 AQ modules on the same S7-1200 station. Each input channel accepts voltage or current signals independently (±10 V down to ±2.5 V, or 4-20 mA\/0-20 mA), so the same module handles transmitters with different signal types without hardware changes. Voltage outputs into loads down to 1000 Ω and current outputs up to 600 Ω cover typical actuator and indicator wiring. Wire-break and short-circuit diagnostics report at the module level, which is useful for detecting field wiring faults without additional sensing hardware.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSuited to small-to-mid S7-1200 stations that need mixed analog I\/O for process values (pressure and temperature transmitters, flow) and proportional outputs (valve positioners, VFD speed references) — skid-mounted machinery, packaging lines, and utility monitoring panels where compact I\/O count matters more than channel isolation.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53960782545179,"sku":"6ES7233-4HF50-0XB0","price":484.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-6es7233-4hf50-0xb0-sm-1233-analog-io-module.png?v=1789663473","url":"https:\/\/stoklink.com\/products\/siemens-6es7233-4hf50-0xb0-sm-1233-analog-io-module","provider":"Stoklink","version":"1.0","type":"link"}
