For equipment identificationpurposes, each coupling link has a blank labeling plate.The semiconductor couplers have a low power consumptionand are therefore particularly well suited for solid-state systems.I/O devices Electronic control Actuators110 V AC110 V AC230 V AC 24 V DC 24 V DC 230 V ACPushbuttonPositionswitchCouplinglinkInputApplication example: Motor controlOutputNSB0_00186CouplinglinkMotorcontactorM■ Technical specificationsType 3TX7 002, 3TX7 003 3TX7 004, 3TX7 005Dimensions (W x H x D)For width B see Selection and ordering dataHmm W x 60 x 62 W x 80 x 845DGeneral technical specificationsRated insulation voltage U i (pollution degree 3) V 300Protective separation 1) between coil and contactsacc. to IEC 60947-1, Appendix N• Solid or finely stranded mm 2 1 x (0.08 ... 2.5)• Finely stranded with end sleeve mm 2 1 x (0.25 ... 1.5)• Corresponding opening toolScrewdriver, size 3.0 mm x 0.5 mm (3RA29 08-1A)1) For 3TX7 00.-1FB02, no protective separation acc. to IEC 60947-1, Appendix N.VUp to 300 ACPermissible ambient temperature• During operation °C -25 ... +60• During storage °C -40 ... +80Degree of protection• Connections•EnclosureShort-circuit protection• Short-circuit test with fuse links of gG operational classwith short-circuit current I k = 1 kA acc. to IEC 60947-5-1Conductor cross-sections(For 3TX7 002, 3TX7 004)A 4IP20IP30Screw terminals• Solid mm 2 1 x (0.25 ... 4)• Finely stranded without end sleeve mm 2 1 x (0.5 ... 2.5)• Finely stranded with end sleeve mm 2 1 x (0.5 ... 2.5)• Terminal screwsM3- Corresponding opening tool Screwdriver, size 3.5 mm x 0.5 mm(For 3TX7 003, 3TX7 005)Spring-type terminalsWType 3TX7 002-,3TX7 003-Control side1AB001AB021BB00 1FB02 1CB00 2AB00 2AE00 1BF002BF022AF002AF05Operating range 0.8 ... 1.25 x U s 0.8 ... 1.1 x U sPower consumption•At U s = 24 V AC/DC W 0.75 1.2 0.75 --•At U s = 230 V AC/DC W -- -- -- 1.2Type 3TX7 004, 3TX7 005 Exception: 3TX7 005-...05Control sideOperating range•At U s = 24 V AC/DC0.7 ... 1.25 x U s•At U s = 110 V AC/DC and 230 V0.8 ... 1.1 x U s- Exception: 3TX7 005-1LN00 0.7 ... 1.25 x U sPower consumption•At U s = 24 V AC/DC W 0.5 --•At U s = 230 V AC VA -- 6•At U s = 230 V DC W -- 1Siemens IC 10 · 20125/39
