Powered by a wide 120 to 240 VAC supply, it integrates twenty-four 24 VDC inputs and sixteen electromechanical relay outputs alongside dual mini-DIN serial communication ports.\u003c\/p\u003e\n\u003ch3\u003eDual Communication Architecture\u003c\/h3\u003e\n\u003cp\u003eThis unit features two 8-pin mini-DIN circular serial ports on its chassis, permitting simultaneous communication tasks without requiring cable disconnection. The front primary serial port supports DF1, DH-485, Modbus RTU, and ASCII protocols for continuous connections to HMIs, SCADA systems, or programming workstations, while the second dedicated port allows online editing and testing.\u003c\/p\u003e\n\u003ch3\u003eEmbedded I\/O and Sensor Power\u003c\/h3\u003e\n\u003cp\u003eThe controller offers 24 digital DC inputs, divided into 20 standard inputs (channels 4 and higher) and 4 fast inputs (channels 0–3) capable of high-speed pulse tracking. The 16 relay output channels handle both AC (120–240 VAC) and DC (24–125 VDC) loads. An internal 24 VDC auxiliary power supply provides up to 400 mA to power connected sensors directly from the controller.\u003c\/p\u003e\n\u003cp\u003eThe 1762-L40BWAR provides a versatile \u003cstrong\u003e120\/240 VAC line-powered\u003c\/strong\u003e automation engine featuring \u003cstrong\u003edual serial ports\u003c\/strong\u003e and \u003cstrong\u003erelay output isolation\u003c\/strong\u003e for reliable small-scale industrial control.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1762-L40BWAR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMicroLogix 1200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Power\u003c\/td\u003e\n\u003ctd\u003e120 to 240 VAC (47–63 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Usage\u003c\/td\u003e\n\u003ctd\u003e82 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInrush Current\u003c\/td\u003e\n\u003ctd\u003e25 A for 8 ms (at 120 VAC) \/ 40 A for 4 ms (at 240 VAC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Inputs\u003c\/td\u003e\n\u003ctd\u003e24 total (20 standard 24 VDC sink\/source, 4 fast 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Outputs\u003c\/td\u003e\n\u003ctd\u003e16 relay outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Contact Rating\u003c\/td\u003e\n\u003ctd\u003e24–125 VDC, 120–240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Sensor Power Output\u003c\/td\u003e\n\u003ctd\u003e24 VDC at 400 mA (400 µF max load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Ports\u003c\/td\u003e\n\u003ctd\u003eTwo (2) 8-pin mini-DIN circular serial ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Protocols\u003c\/td\u003e\n\u003ctd\u003eDF1, DH-485, Modbus, ASCII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C (32 to 131 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.13 lbs (0.96 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the secondary programming port on the 1762-L40BWAR? A: The second 8-pin mini-DIN port allows engineers to perform online ladder edits, monitor test functions, and download program revisions simultaneously without disconnecting existing HMI or SCADA networks attached to the primary port.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 24 VDC sensor power supply be used to power the controller's output load circuits? A: No, the 24 VDC sensor supply has its common internally connected to chassis ground and is rated for a maximum of 400 mA; it must be reserved for input field sensors rather than output load switching.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53088210026776,"sku":"1762-L40BWAR","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1762-L24BWA2_Cocoai.jpg?v=1789437863","url":"https:\/\/www.innoplcsync.com\/products\/programmable-controller-allen-bradley-1762-l40bwar-micrologix-1200","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
