It includes C-bus capability for connecting expansion racks. Weighing approximately 600 g, this module draws a maximum of 140 mA from the 5 V DC backplane bus and supports cable lengths up to 5 meters between the first and last interface module.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Configuration\u003c\/h2\u003e\n\u003cp\u003eThis module operates as the sending interface in a central coupling configuration, paired with a receiving IM 461-0 module in the expansion rack. The maximum cable length between the first and last interface module is 5 meters. A termination plug (6ES7461-0AA0-7AA0) is required for proper bus termination. The module fits into UR1, UR2, and CR2 central racks and provides two front connectors for expansion strand connections.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n  \u003ctbody\u003e\n    \u003ctr style=\"background-color: #f2f2f2;\"\u003e\n      \u003cth style=\"padding: 8px; border: 1px solid #ddd; text-align: left;\"\u003eParameter\u003c\/th\u003e\n      \u003cth style=\"padding: 8px; border: 1px solid #ddd; text-align: left;\"\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eManufacturer\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eSiemens\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003ePart Number\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e6ES7460-0AA01-0AB0\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eProduct Type\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eSend IM 460-0 Interface Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eSeries\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eSIMATIC S7-400\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eFunction\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eCentral coupling without PS transfer, with C-bus\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eInput Current (Backplane 5V DC)\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eMax 140 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003ePower Loss (Max)\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e700 mW\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eMax Cable Length\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e5 m (between first and last interface module)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eTermination Plug\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e6ES7461-0AA0-7AA0\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eDimensions (W x H x D)\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003e25 x 290 x 280 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"padding: 8px; border: 1px solid #ddd;\"\u003eApprox. 600 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eInstallation Guide\u003c\/h2\u003e\n\u003cp\u003eInsert the Send IM 460-0 into a compatible S7-400 central rack slot (UR1, UR2, or CR2).

The integrated C-bus supports communication between the central controller and expansion racks. The 5-meter cable limit ensures signal integrity for short-distance coupling. Low power consumption of 140 mA and 700 mW power loss minimize thermal load in the control cabinet. The compact 25 mm width preserves rack space for additional I\/O modules.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: What is the function of the 6ES7460-0AA01-0AB0?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA1:\u003c\/strong\u003e This is a Send IM 460-0 interface module for central coupling without power supply transfer, equipped with C-bus for connecting S7-400 expansion racks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What termination plug is required for this module?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA2:\u003c\/strong\u003e The module requires termination plug 6ES7461-0AA0-7AA0 for proper bus termination at the final receiving module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What is the maximum cable length supported?\u003c\/strong\u003e\u003cbr\u003e\n\u003cstrong\u003eA3:\u003c\/strong\u003e The maximum cable length between the first and last interface module is 5 meters.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":67877330813060,"sku":"6ES7460-0AA01-0AB0","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/6ES7460-0AA01-0AB0.jpg?v=1794396495","url":"https:\/\/www.etowonauto.com\/tr\/products\/6es7460-0aa01-0ab0-central-coupling-module-siemens","provider":"Etowon Auto","version":"1.0","type":"link"}
