{"product_id":"schneider-electric-tm251mese","title":"Schneider Electric TM251MESE Modicon M251 Dual Ethernet Programmable Logic Controller","description":"\u003cp\u003eThe Schneider Electric TM251MESE is a Modicon M251 programmable logic controller with two independent Ethernet ports (Ethernet 1 and Ethernet 2), supporting up to 7 local or 14 remote I\/O expansion modules. Powered by 24 V DC with a 50 A inrush current and 32.6-40.4 W consumption, it suits applications needing network segregation — one Ethernet port for machine control, the other for plant-level supervision.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference\u003c\/td\u003e\n\u003ctd\u003eTM251MESE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGTIN\u003c\/td\u003e\n\u003ctd\u003e3606480648878\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003eModicon M251\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eLogic controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage Limits\u003c\/td\u003e\n\u003ctd\u003e20.4-28.8 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInrush Current\u003c\/td\u003e\n\u003ctd\u003e50 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e32.6-40.4 W (max I\/O expansion)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax I\/O Expansion Modules\u003c\/td\u003e\n\u003ctd\u003e7 local \/ 14 remote\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Ports\u003c\/td\u003e\n\u003ctd\u003eUSB mini B, RS232\/RS485 serial (RJ45), Ethernet 1 10BASE-T\/100BASE-TX (2-port switch), Ethernet 2 10BASE-T\/100BASE-TX (1 port)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Connected Devices\u003c\/td\u003e\n\u003ctd\u003e16 EtherNet\/IP, 64 Modbus TCP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory\u003c\/td\u003e\n\u003ctd\u003e64 MB system RAM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Backup\u003c\/td\u003e\n\u003ctd\u003e128 MB built-in flash (user program backup)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Storage\u003c\/td\u003e\n\u003ctd\u003e≤16 GB SD card (optional)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003eBR2032 lithium, 4-year life\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackup Time\u003c\/td\u003e\n\u003ctd\u003e2 years at 25 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eTH35-15 \/ TH35-7.5 DIN rail, panel mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x D x H)\u003c\/td\u003e\n\u003ctd\u003e54 x 95 x 90 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e0.22 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Degree of Protection\u003c\/td\u003e\n\u003ctd\u003eIP20 (protective cover in place)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-10...55 °C (horizontal) \/ -10...35 °C (vertical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCE\u003c\/li\u003e\n\u003cli\u003ecULus\u003c\/li\u003e\n\u003cli\u003eUKCA\u003c\/li\u003e\n\u003cli\u003eDNV-GL\u003c\/li\u003e\n\u003cli\u003eABS\u003c\/li\u003e\n\u003cli\u003eLR\u003c\/li\u003e\n\u003cli\u003eANSI\/ISA 12-12-01\u003c\/li\u003e\n\u003cli\u003eCSA C22.2 No 142\u003c\/li\u003e\n\u003cli\u003eCSA C22.2 No 213\u003c\/li\u003e\n\u003cli\u003eIEC 61131-2:2007\u003c\/li\u003e\n\u003cli\u003eMarine specification\u003c\/li\u003e\n\u003cli\u003eUL 508\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eChoose the TM251MESE over a CANopen-equipped variant when the machine needs two separate Ethernet networks instead of a fieldbus — Ethernet 1 handles EtherNet\/IP and Modbus TCP device control while Ethernet 2 can be dedicated to plant supervision or a second protocol stack, avoiding network congestion on a single port. Its 7 local \/ 14 remote expansion-module ceiling matches the CANopen variant, so the choice comes down to fieldbus versus dual-Ethernet architecture.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54072474992923,"sku":"TM251MESE","price":834.79,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-tm251mese-m251-plc.jpg?v=1790802127","url":"https:\/\/stoklink.com\/products\/schneider-electric-tm251mese","provider":"Stoklink","version":"1.0","type":"link"}
