Power loss runs 1.7 W typ. Address space is 8 bytes. Supports both two-wire and four-wire voltage connections. ## Output specs and protection Voltage outputs are short-circuit protected per channel, electronic to chassis, with a max short-circuit current of 50 mA. Minimum load is 1 000 Ω. Resistive load response 0.1 ms; capacitive load 6 ms. Isolation tested at 707 V DC between channels and backplane bus. Output ranges cover the standard industrial signals: 0 to 10 V, 1 to 5 V, and -10 to +10 V. Accuracy ±0.15 % relative to output range. Shielded cable max 30 m. ## Diagnostics and configuration Parameterizable diagnostic alarm reports faults per channel. Group error SF (red) LED on the front. Substitute values can be set. Diagnostic information is readable via the bus. Short-circuit detection is per channel, but not active in the zero range — watch the dead band. No hardware interrupt, no wire-break detection. Reverse polarity protection is fitted against destruction. The module is isolated between channels and backplane.","metaTitle":"Siemens 6ES7145-4FF00-0AB0 Analog Output Module 4 AO Voltage","metaDescription":"Siemens S7-1200 analog output module 4 voltage channels, 0.7 ms conversion, 0 to 10 V / -10 to +10 V, 1 V to 5 V, per-channel short-circuit protection, diagnostic alarm.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLC I/O & Expansion Modules"],"specifications":{"Depth":"35 mm","Width":"45 mm","title":"6ES7145-4FF00-0AB0","Height":"130 mm","0 to 10 V":"Yes","1 V to 5 V":"Yes","Wire-break":"No","description":"SIMATIC DP, Electronic modules for ET 200 PRO 4 AO U High Feature, +-10 V; 0...10V; 1...5V, Channel diagnostics; incl. bus module, Connection module IO 6ES7194-4..00-0AA0 order separately","Short-circuit":"Yes; per channel, not in zero range","-10 V to +10 V":"Yes","Shielded, Max.":"30 m","Weight, approx.":"150 g","lifecycle_stage":"current","Diagnostic alarm":"Yes; Parameterizable","Power loss, typ.":"1.7 W","Rated value (DC)":"24 V","Number of outputs":"4","For Resistive Load":"0.1 ms","Hardware interrupt":"No","up to 55 °C, max.":"1 A","For Capacitive Load":"6 ms","Between The Channels":"No","Group error SF (red)":"Yes","Isolation tested with":"707 V DC (type test)","Number of analog outputs":"4","Short-circuit protection":"Yes; per module","With Voltage Outputs, Min.":"1 000 Ω","Reverse polarity protection":"Yes; against destruction","Conversion time (per channel)":"0.7 ms","Substitute values connectable":"Yes","from supply voltage 1L+, max.":"65 mA","Address space per module, max.":"8 byte","Cycle time (all channels) max.":"3 ms","Diagnostic information readable":"Yes","from backplane bus 3.3 V DC, max.":"10 mA","Voltages at the outputs towards MANA":"16 V; Permanent","Between The Channels And Backplane Bus":"Yes","For Voltage Output Two-Wire Connection":"Yes","For Voltage Output Four-Wire Connection":"Yes","Voltage output, short-circuit protection":"Yes; per channel, electronic to chassis","Voltage, relative to output range, (+/-)":"0.15 %","Voltage output, short-circuit current, max.":"50 mA","With Voltage Outputs, Capacitive Load, Max.":"1 µF","Linearity error (relative to output range), (+/-)":"0.1 %","Temperature error (relative to output range), (+/-)":"0.01 %/K","Resolution with overrange (bit including sign), max.":"15 bit; at -10 to +10 V; 14 bit at 1 to 5 V; 15 bit at 0 to 10 V","Output ripple (relative to output range, bandwidth 0 to 50 kHz), (+/-)":"0.02 %","Repeat accuracy in steady state at 25 °C (relative to output range), (+/-)":"0.05 %"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$193.04 – $567.72","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/3f149ebcec25e8ae9001bc920417e0de.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=447999&mlfb=6ES7145-4FF00-0AB0"},"ai":{"faq":[{"question":"Does the module have short-circuit protection?","answer":"Yes, per-channel electronic short-circuit protection, effective except in the zero range."},{"question":"What is the conversion time?","answer":"0.7 ms per channel, max cycle time 3 ms for all channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/6ES7145-4FF00-0AB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/6ES7145-4FF00-0AB0 when reusing this data.
