Please use theFX3U Series programmable logic controllers while installed inconductive shielded control boxes. Please secure the control box lidto the control box (for conduction). Installation within a control boxgreatly affects the safety of the system and aids in shielding noisefrom the programmable logic controller.Caution for Analog Products in useThe analog special adapters have been found to be compliant to theEuropean standards in the aforesaid manual and directive. However,for the very best performance from what are in fact delicatemeasuring and controlled output device Mitsubishi Electric would liketo make the following points;As analog devices are sensitive by nature, their use should beconsidered carefully. For users of proprietary cables (integral withsensors or actuators), these users should follow thosemanufacturers installation requirements.Mitsubishi Electric recommend that shielded cables should be used.If NO other EMC protection is provided, then users may experiencetemporary induced errors not exceeding 10%/-10% in very heavyindustrial areas.However, Mitsubishi Electric suggest that if adequate EMCprecautions are followed with general good EMC practice for theusers complete control system, users should expect normal errorsas specified in this manual.- Sensitive analog cable should not be laid in the same trunkingor cable conduit as high voltage cabling. Where possible usersshould run analog cables separately.- Good cable shielding should be used. When terminating theshield at Earth - ensure that no earth loops are accidentallycreated.- When reading analog values, EMC induced errors can besmoothed out by averaging the readings. This can be achievedeither through functions on the analog special adapter/block orthrough a users program in the FX3U Series PLC main unit.Manual nameFX3U SeriesUser's Manual- HardwareEditionManual X13X14X15X16X17X20X21X22X23X24X25X26X270 1 2 3 4 5 6 7 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 60 1 2 3 4 5 6 7 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 17RUNRUNOUT0 1 2 3 4 5 6 7 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 0Y22Y24Y26COM5COM4 ROR0 1 2 3 4 5 6 7 20 21 22 23 24 25 26 27100 111 122 133 144 155 166 177 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 M5COM4 Y15Y17Y21Y23Y25Y27RNo.1.1.1OutlinePart BATTFX3U-48MR/ESOUTFX3U-48MERROR0 1 2 3 4 5 6 7 20 21 22 23 24 25 26 27100 111 122 133 144 155 166 177 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 17Y4Y6COM2Y5Y7Y10Y12COM3Y11Y13NameProtective terminal covers (FX3U- M / -A is excluded)Power supply, Input (X) terminalsTerminal block mounting screws(FX3U-16M terminal block cannot be installed/removed)Terminal namesOutput (Y) terminals1.2X270 1 2 3 4 5 6 7 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 17POWERExternal dimensions and weight2- 4.5-diam mounting holes (FX3U-16M , FX3U-32M )4- 4.5-diam mounting holes (FX3U-48M , FX3U-64M ,FX3U-80M ,FX3U-128M )FX3U-16M and FX3U-32M do not have the (*)-marked mounting holes.Y14Y16Y20Y22Y24Y26COM5COM4 X20X21X22X23X24X25X26X270 1 2 3 4 5 6 7 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 17POWERRUNNo.BATTNameFX3U-48MR/ESOUTFX3U-48MTop coverBattery coverExplains FX3U Series PLCspecification details for I/O,wiring, installation, andmaintenance.FX3U/FX3UCSeriesProgrammingManual- Basic & AppliedInstruction EditionJY997D16601MODEL CODE:09R517Describes PLCprogramming for basic/applied instructions STL/SFC programming anddevices.FX Series User’sManual - DataCommunicationEditionJY997D16901MODEL CODE:09R715Explains N:N link, parallellink, computer link, noprotocol communication byRS instructions/FX2N232IF.FX3U / FX3UCSeriesUser's Manual- Analog ControlEditionJY997D16701MODEL CODE:09R619Describes specifications foranalog control andprogramming methods forFX3U / FX3UC Series PLC.JY997D16801MODEL CODE:09R620Explains the specificationsfor positioning control ofFX3U / FX3UC Series andprogramming proceduresHow to obtain manualsFor the necessary product manuals or documents, consult with theMitsubishi Electric dealer from where you purchase your product.LRUNJY997D16501MODEL CODE:09R516FX3U / FX3UCSeriesUser's Manual- PositioningControl EditionCheck if the following product and items are included in the package:ProductManualDust proof sheet(1 sheet)Y0Y2COM1Y1Y3Associated manualsFX3U Series PLC (main unit) comes with this document (hardwaremanual).For a detailed explanation of the FX3U Series hardware andinformation on instructions for PLC programming and specialextension unit/block, refer to the relevant documents.With terminal cover openIncorporated Items80(3.15")90(3.55")Requirement for Compliance with LVD 22Y24Y26COM5COM4 Y15Y17Y21Y23Y25Y27*RSpecial adapter connecting hooks (2 places)Expansion board dummy coverRUN/STOP switchPeripheral device connecting connectorERROR0 1 2 3 4 5 6 7 20 21 22 23 24 25 26 27100 111 122 133 144 155 166 177 20 21 22 23 24 25 26 2710 11 12 13 14 15 16 17Y4Y6COM2Y5Y7DIN rail mounting hooks22(0.87")W1WModel nameW:mm (inches)9(0.36")86(3.39")Mounting hole pitchesW1:mm (inches)Direct mountinghole pitchesMASS(Weight):kg (lbs)Model name (abbreviation)Input display LEDs (Red)FX3U-16M130 (5.12”)103 (4.06”)0.6 (1.32lbs)Terminal block coversFX3U-32M150 (5.91”)123 (4.85”)0.65 (1.43lbs)0.85 (1.87lbs)Extension device connecting connector coverFX3U-48M182 (7.17”)155 (6.11”)Operation status display LEDsFX3U-64M220 (8.67”)193 (7.6”)1.00 (2.2lbs)POWERGreen On while power is on the PLC.FX3U-80M285 (11.23”)258 (10.16”)1.20 (2.64lbs)RUNGreen On while the PLC is running.FX3U-128M350 (13.78”)323 (12.72”)1.80 (3.96lbs)BATTERRORRedLights when the battery voltage drops.RedFlashing when a program error occurs.RedLights when a CPU error occurs.Output display LEDs (Red)*1*1 FX3U-128Mdoes not have DC power supply.Installation 35-mm-wide DIN rail or Direct (screw) mounting (M4)

3.Power supply/input/output specificationsand examples of external wiringAs for the details of the power supply wiring and input/output wiring,refer to FX3U Series User's Manual - Hardware Edition.DESIGNPRECAUTIONS Make sure to have the following safety circuits outside of thePLC to ensure safe system operation even during externalpower supply problems or PLC failure.Otherwise, malfunctions may cause serious accidents.1) Most importantly, have the following: an emergency stopcircuit, a protection circuit, an interlock circuit for oppositemovements (such as normal vs. reverse rotation), and aninterlock circuit (to prevent damage to the equipment at theupper and lower positioning limits).2) Note that when the PLC CPU detects an error, such as awatchdog timer error, during self-diagnosis, all outputs areturned off. Also, when an error that cannot be detected bythe PLC CPU occurs in an input/output control block,output control may be disabled.External circuits and mechanisms should be designed toensure safe machinery operation in such a case.3) Note that when an error occurs in a relay, triac or transistoroutput device, the output could be held either on or off.For output signals that may lead to serious accidents,external circuits and mechanisms should be designed toensure safe machinery operation in such a case. Connect the AC power supply to the dedicated terminalsspecified in this manual.If an AC power supply is connected to a DC input/outputterminal or DC power supply terminal, the PLC will burn out. Do not wire vacant terminals externally.Doing so may damage the product. Use class D grounding (grounding resistance of 100Ω or less)with a wire of 2mm2 or thicker on the grounding terminal of theFX3U Series main unit.However, do not connect the ground terminal at the same pointas a heavy electrical system. When drilling screw holes or wiring, make sure cutting or wiredebris does not enter the ventilation slits.Failure to do so may cause fire, equipment failures ormalfunctions.Notes Input/output wiring 50 to 100 m (164’1” to 328’1”) long willcause almost no problems of noise, but, generally, the wiringlength should be less than 20 m (65’7”) to ensure the safety. Extension cables are easily affected by noise. Lay the cablesat a distance of at least 30 to 50 mm (1.19” to 1.97”) away fromthe PLC output and other power lines.3.1Wiring3.1.1DESIGNPRECAUTIONS Do not bundle the control line together with or lay it close to themain circuit or power line. As a guideline, lay the control line atleast 100mm (3.94") or more away from the main circuit orpower line.Noise may cause malfunctions. Install module so that excessive force will not be applied to thebuilt-in programming connectors, power connectors or I/Oconnectors.Failure to do so may result in wire damage/breakage or PLCfailure.Notes Simultaneously turn on and off the power supplies of the mainunit and extension devices. Even if the power supply causes an instantaneous power failurefor less than 10 ms, the PLC can continue to operate. If a long-time power failure or an abnormal voltage drop occurs,the PLC stops, and output is turned off. When the powersupply is restored, it will automatically restart (when the RUNinput is on).WIRINGPRECAUTIONS Cut off all phases of the power supply externally beforeinstallation or wiring work in order to avoid damage to theproduct or electric shock.3.2WIRINGPRECAUTIONSPower supply specificationsThe specifications for the power supply of the main unit areshown in the following table.SpecificationItemAC power typeSupply voltageφ3.2 (0.13")6.2 mm (0.24")or less24 V DCAllowable supply voltagerange85 - 264V AC16.8-28.8V DC*6Rated frequency50/60HzAllowable instantaneouspower failure timeOperation can becontinued uponoccurrence ofinstantaneouspower failure for10 ms or less. *4PowerfuseFX3U-16M32MtoFX3U-48M128M *5to6.2 mm (0.24")or less’[ŽqTerminal When two wires are connected to one terminalφ3.2 (0.13")6.2 mm (0.24")or lessTerminal Solderlessscrewterminal6.3 mm(0.25")or moreφ3.2 (0.13")6.2 mm (0.24")or lessTerminal6.3 mm(0.25")or moreRemoval and installation of quick-release terminalblockUnscrew the terminal block mounting screw [both rightand left screws] evenly, and remove the terminal block.Installation Place the terminal block in the specified position, andtighten the terminal block mounting screw evenly [bothright and left screws].Tightening torque 0.4 to 0.5 N m* Pay attention so that the center of the terminal blockis not lifted.250V AC3.15A250V AC5AOperation can becontinued uponoccurrence ofinstantaneouspower failure for 5ms or V DCservicepowersupply*2*5FX3U-48M128M *5to5V DC built-in powersupply*3100 to 240V ACBreakerPower onPLPLC65W 400 mA or less 600 mA or less MCFuse*MC*Class D groundingRefer to section 3.3for details.DCpowersupplyDCACPower supply for loads connectedto PLC output terminals3.2.3Example of external wiring (DC power type)24V DC power is supplied to the main unit.
