It runs the integrated Freeport, ASCII, and Modbus RTU master\/device protocol drivers, draws 200 mA max from the backplane 5 V DC bus, and dissipates 1.1 W typical.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e6ES7241-1AH32-0XB0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSIMATIC S7-1200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type Designation\u003c\/td\u003e\n\u003ctd\u003eCM 1241 RS 232\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface Type\u003c\/td\u003e\n\u003ctd\u003eRS 232C (V.24)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Interfaces\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoint-to-Point Cable Length, max.\u003c\/td\u003e\n\u003ctd\u003e10 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntegrated Protocols\u003c\/td\u003e\n\u003ctd\u003eFreeport, ASCII, Modbus RTU master, Modbus RTU device\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFreeport Telegram Length, max.\u003c\/td\u003e\n\u003ctd\u003e1 kbyte\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModbus RTU Master Address Range\u003c\/td\u003e\n\u003ctd\u003e1 to 49,999\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModbus RTU Master Devices, max.\u003c\/td\u003e\n\u003ctd\u003e247\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModbus RTU Device Address Range\u003c\/td\u003e\n\u003ctd\u003e1 to 49,999\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage, Rated (DC)\u003c\/td\u003e\n\u003ctd\u003e24 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage Range (DC)\u003c\/td\u003e\n\u003ctd\u003e20.4 V to 28.8 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption, max.\u003c\/td\u003e\n\u003ctd\u003e200 mA, from backplane bus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Loss, typ.\u003c\/td\u003e\n\u003ctd\u003e1.1 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDegree of Protection\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions, W x H x D\u003c\/td\u003e\n\u003ctd\u003e30 x 100 x 75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight, approx.\u003c\/td\u003e\n\u003ctd\u003e150 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCE mark\u003c\/li\u003e\n\u003cli\u003eCSA approval\u003c\/li\u003e\n\u003cli\u003eUL approval\u003c\/li\u003e\n\u003cli\u003ecULus\u003c\/li\u003e\n\u003cli\u003eFM approval\u003c\/li\u003e\n\u003cli\u003eRCM\u003c\/li\u003e\n\u003cli\u003eKC approval\u003c\/li\u003e\n\u003cli\u003eMarine approval\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003ePick the CM 1241 RS232 over the RS485 variant when the connected device -- a modem, barcode scanner, or legacy instrument -- only speaks single-ended RS 232C, since the two interfaces are not interchangeable at the connector or the electrical level. Its 10 m maximum cable length keeps it to point-to-point runs; multidrop or longer-distance links need the RS485 CM 1241 instead. Because Modbus RTU master and device modes are both built into the firmware, the same module can poll a third-party RS232 device as master in one project and answer as a Modbus slave in another without swapping hardware.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eConnecting an S7-1200 CPU to RS232 barcode scanners, weigh indicators, printers, or legacy PLCs and instruments over a Freeport or Modbus RTU serial link.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53960782676251,"sku":"6ES7241-1AH32-0XB0","price":178.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/siemens-6es7241-1ah32-0xb0-cm-1241-rs232-communication-module.png?v=1789663258","url":"https:\/\/stoklink.com\/products\/siemens-6es7241-1ah32-0xb0-cm-1241-rs232-module","provider":"Stoklink","version":"1.0","type":"link"}
