Module width is 60 mm on the backplane (overall housing 87 mm), depth 55 mm, height 110 mm. M12 connectors keep the gland plate clean — shielded runs up to 30 m. Two-wire, three-wire, and four-wire Pt100 connections are supported with a 10 MΩ input resistance that doesn't load the sensor. Supply draw from L+ is 40 mA max; the module dissipates 0.9 W typical — negligible for the bus coupler budget but worth noting if you're stacking a dozen of these on a segment. ## Diagnostics and accuracy Diagnostic alarm, limit value alarm (upper/lower, channel-selectable), hardware interrupt, and overflow/underflow detection are all present and parameterizable. Group error SF (red) LED gives a visual heads-up on the module face. Common-mode rejection is at least 60 dB, crosstalk between inputs stays below -45 dB, and linearity error holds within ±0.05 % of the input range. Resolution is 12 bits plus sign, with overrange to 17.5 %. Temperature drift is ±0.01 %/K of input range; overall accuracy for resistance measurement with Pt100 is ±1.2 % of input range — consistent with a clean industrial-grade RTD input that doesn't need constant re-calibration.","metaTitle":"Siemens 6ES7144-1JB31-0XB0 ET200S RTD Module, 2 AI Pt100","metaDescription":"Active-production Siemens 6ES7144-1JB31-0XB0 distributed I/O module for Pt100 RTD inputs, two analog inputs, M12 connectors, diagnostic alarms, parameterizable, 55 mm depth.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Analog Input Modules"],"specifications":{"Depth":"55 mm","Width":"87 mm; Width module 60 mm","Height":"110 mm","Pt 100":"Yes; Standard","Wire-break":"Yes; channel by channel","Shielded, Max.":"30 m","Parameterizable":"Yes","Weight, approx.":"250 g","lifecycle_stage":"current","Diagnostic alarm":"Yes","Power loss, typ.":"0.9 W","Limit value alarm":"Yes; upper limit, channel by channel/ lower limit channel by channel","Hardware interrupt":"Yes","Overflow/underflow":"Yes; channel by channel","Analog value display":"S7 Format / S5 Format","Diagnostics function":"Yes; Parameterizable","Group error SF (red)":"Yes","Integration time (ms)":"16,7 / 20 ms","Measurement principle":"integrating","Resistance thermometer":"Yes","Number of analog inputs":"2","Input resistance (Pt 100)":"10 MΩ","from supply voltage L+, max.":"40 mA","Common mode interference, min.":"60 dB","Cycle time (all channels) max.":"134 / 160","Between the inputs and MANA (UCM)":"2 V DC / 2 Vpp AC","Integration time, parameterizable":"Yes","Crosstalk between the inputs, min.":"45 dB","Potential separation analog inputs":"No","between MANA and M internally (UISO)":"0V AC; DC","Current, relative to input range, (+/-)":"1 %","Voltage, relative to input range, (+/-)":"1 %","Linearity error (relative to input range), (+/-)":"0.05 %","Temperature error (relative to input range), (+/-)":"0.01 %/K","For Resistance Measurement With Two-Wire Connection":"Yes","For Resistance Measurement With Four-Wire Connection":"Yes","Resolution with overrange (bit including sign), max.":"12 bit; + sign; overrange 17.5%","For Resistance Measurement With Three-Wire Connection":"Yes","Resistance thermometer, relative to input range, (+/-)":"1.2 %","Design of electrical connection for the inputs and outputs":"4/5-pin M12 circular connectors","Constant measurement current for resistance-type transmitter, typ.":"1.5 mA","Interference voltage suppression for interference frequency f1 in Hz":"50 / 60 Hz","Permissible Input Voltage For Voltage Input (Destruction Limit), Max.":"30 V","Repeat accuracy in steady state at 25 °C (relative to input range), (+/-)":"0.05 %","Series mode interference (peak value of interference < rated value of input range), min.":"40 dB"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$558.80","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/eaa2d09cb181f4f534f179bc0da588d0.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=309050&mlfb=6ES7144-1JB31-0XB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/6ES7144-1JB31-0XB0/alternatives.json"},"ai":{"faq":[{"question":"What is the module depth and width?","answer":"Depth 55 mm; the module width on the backplane is 60 mm (overall housing 87 mm)."},{"question":"What connector type does it use for field wiring?","answer":"4/5-pin M12 circular connectors.
