It supports TCP/IP, NTP for network time synchronisation, and SNMP v1 for basic network management—carrying an MIB for structured device interrogation. This module sits on the S7-300 DIN rail, occupying two slot widths (125 mm high, 80 mm wide, 120 mm deep). It draws 0.2 A from the backplane 5 V supply and requires an additional external 24 V DC connection via the 2-pole pluggable terminal block. Power dissipation is 5.8 W, and the module is rated IP20 with an operating range of 0 to 40 °C for vertical installation. Storage and transport tolerances extend from -40 to +70 °C.","metaTitle":"Siemens 6GK7343-1EX20-0XE0 CP, RJ45, NTP, SNMP v1","metaDescription":"Active S7-300 double-width CP, 10/100 Mbps RJ45, NTP and SNMP v1 support, 5.8W power loss, sourced to RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLC Communication Modules"],"specifications":{"DCP":"No","NTP":"Yes","LLDP":"No","Depth":"120 mm","Width":"80 mm","Height":"125 mm","TCP/IP":"Yes","at 5 V":"5 %","Maximum":"16","SNMP v1":"Yes","at 24 V":"5 %","Required":"STEP 7 V5.2 or higher","Module Format":"Compact module S7-300 double width","During Storage":"-40 ... +70 °C","Supply Voltage":"5 V","power loss [W]":"5.8 W","lifecycle_stage":"current","During Transport":"-40 ... +70 °C","For Power Supply":"2-pole plugable terminal block","protection class IP":"IP20","At The 1st Interface":"10 ... 100 Mbit/s","S7-300 rail mounting":"Yes","Security Information":"Siemens provides products and solutions with industrial security functions that support the secure operation of plants, solutions, machines, equipment and/or networks. They are important components in a holistic industrial security concept. With this in mind, Siemens’ products and solutions undergo continuous development. Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action(e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept. Third-party products that may be in use should also be considered. For more information about industrial security, visit http://www.siemens.com/industrialsecurity.
