Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 140DAO84220 is a Schneider Modicon Quantum automation platform AC discrete output module, order code 140DAO84220, delivering 16 isolated outputs arranged as 4 channels of 4 points each, rated for 20-56 V AC and 16 A switching current. It draws 1.85 W from the backplane and carries UL 508, CSA C22.2 No 142, and CE markings, with FM Class 1 Division 2 and cUL certifications for hazardous-location installations. Each of the four groups of four outputs is isolated from the others and from the backplane, allowing independent AC loads on different phases or circuits. The module switches AC voltages from 20 to 56 V AC at up to 16 A per output, with a dv/dt rating of 400 V/ms that defines the maximum rate of voltage rise the output triacs can commutate without false triggering — critical when driving inductive loads such as contactors, solenoids, or small motors. Internal protection consists of an RC snubber across each output and a 5 A fuse per group; the module signals a blown fuse or loss of field power via dedicated fault LEDs. Sixteen green LEDs indicate individual output status, one green LED shows bus communication active, and one red LED flags an external fault. Addressing requires one output word in the Quantum backplane. The absolute maximum output withstands 100 Vrms for one cycle AC, 63 Vrms for 10 seconds AC, and 111 Vrms for 1.3 seconds AC — transient ratings that inform coordination with upstream protective devices during fault clearing. ## Applications The isolated groups suit applications mixing loads on different phases or requiring galvanic separation between safety-related and standard outputs, such as valve manifolds, alarm annunciators, and motor starter coils. Within the Modicon Quantum range, the 140DAO84220 fills the niche for medium-current AC output groups — higher per-point current than the 140DAO84000C (which switches 1 mA signal-level loads) but fewer channels (4 groups vs. 16 individually isolated groups).","metaTitle":"Schneider 140DAO84220 Modicon Quantum AC Discrete Output Module","metaDescription":"Schneider Modicon Quantum 140DAO84220 AC discrete output module: 16 outputs, 4 channels, 20-56 V AC, 16 A switching, dv/dt 400 V/ms, UL 508, CE.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"DV/dt":"400 V/ms","Marking":"CE","Category":"US1PC2118155","Standards":"UL 508 CSA C22.2 No 142","Module format":"Standard","Response Time":"<= 0.5 ms at state 1 to state 0","Surge current":"45 A during 1 cycle per group 25 A during 2 cycles per group 30 A during 3 cycles per group","Protection Type":"Internal by RC filter Internal output protection by 5 A fuse","lifecycle_stage":"eol_hot","Fault indication":"Blown fuse Loss of field power","Local signalling":"1 LED (green) for bus communication is present (Active) 1 LED (red) for external fault detected (F) 16 LEDs (green) for input status","Range of Product":"Modicon Quantum automation platform","Supply frequency":"47...63 Hz","Group of channels":"4 groups of 4 channels","Power dissipation":"1.85 + (1.1 V x total module load current)","Relative Humidity":"95 % without condensation","Operating altitude":"<= 16404.2 ft (5000 m)","Maximum Voltage Drop":"1.5 V","Maximum load current":"16 A rms per module 4 A rms per group 4 A rms 20...56 V per output","Nbr. of units in pkg.":"1","Addressing requirement":"1 output word","Discrete output number":"16","Absolute maximum output":"100 Vrms 1 cycle AC 63 Vrms 10 s AC 111 Vrms 1.3 s AC","Bus current requirement":"350 mA","Discrete output voltage":"20...56 V AC","Product or Component Type":"AC discrete output modules","Electromagnetic compatibility":"Electrostatic discharge immunity test - test level: 4 kV (contact discharge) conforming to IEC 801-2 Electrostatic discharge immunity test - test level: 8 kV (air discharge) conforming to IEC 801-2 Susceptibility to electromagnetic fields - test level: 10 V/m (80...1000 MHz) conforming to IEC 801-3","Ambient Air Temperature for Storage":"-40...185 °F (-40...85 °C)","Ambient Air Temperature for Operation":"32...140 °F (0...60 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$994.79 – $1,987.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/e4761b7af2f2d8572c7a9a75d6df6f1d.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/140DAO84220/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/140DAO84220","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/140DAO84220 when reusing this data.
