Powered by a 24 VDC nominal supply, this self-contained controller integrates 10 discrete I\/O channels, non-volatile EEPROM memory, and an isolated communication interface into a small-footprint enclosure designed for standalone machine automation and localized process control.\u003c\/p\u003e\n\u003ch3\u003ePower Architecture and Operational Constraints\u003c\/h3\u003e\n\u003cp\u003eThe unit operates on an input voltage range of 20.4 to 26.4 VDC with a power consumption of 5 Watts (10 Watts maximum rating) and an inrush current capability of 30 A for 4 ms. The internal 24 VDC power ground and chassis ground are connected internally, providing 1500 VAC isolation. Environmental tolerance spans 0 to 55 deg C (32 to 131 deg F) during horizontal DIN rail or panel mounting, reducing to 0 to 45 deg C (32 to 113 deg F) under vertical installation orientation.\u003c\/p\u003e\n\u003ch3\u003eI\/O Signal Characteristics and Switching Capabilities\u003c\/h3\u003e\n\u003cp\u003eThe controller incorporates 6 24 VDC discrete inputs with an operating voltage range of 14 to 30 VDC (nominal 8.0 mA at 24 VDC; maximum 12.0 mA at 30 VDC). The output section features 4 mechanical relay contact outputs supporting continuous currents of 2.5 A at 120\/240 VAC, 1.0 A at 24 VDC, and 2.0 A at 125 VDC. A Master Control Relay circuit provides standard emergency shutdown protection across output branches.\u003c\/p\u003e\n\u003ch3\u003eMemory Allocation and Execution Performance\u003c\/h3\u003e\n\u003cp\u003eExecution is handled by an embedded system processor utilizing 1K EEPROM memory allocated for 737 instruction words and 437 data words, supporting up to 40 software timers. Performance metrics include a program scan time of 2.0 ms per Kword and an I\/O scan time of 0.21 ms. Direct network connectivity and programming are established via a single RS-232 serial interface utilizing the DF1 protocol.\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\u003e1761-L10BWB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eMicroLogix 1000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eProgrammable Logic Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e20.4-26.4 VDC (24 VDC nominal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e5 W (10 W max)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInrush Current\u003c\/td\u003e\n\u003ctd\u003e30 A for 4 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Inputs\u003c\/td\u003e\n\u003ctd\u003e6 (24 VDC, 14-30 VDC range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Outputs\u003c\/td\u003e\n\u003ctd\u003e4 Contacts (2.5 A at 120\/240 VAC, 1.0 A at 24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory\u003c\/td\u003e\n\u003ctd\u003e1 K EEPROM (737 instruction words, 437 data words)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScan Performance\u003c\/td\u003e\n\u003ctd\u003e2.0 ms\/Kword program scan, 0.21 ms I\/O scan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003e1 x RS-232 (DF1 protocol)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C (Horizontal), 0 to 45 deg C (Vertical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4.72 x 1.57 x 3.15 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.50 lbs (0.68 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifecycle Status\u003c\/td\u003e\n\u003ctd\u003eDiscontinued \/ Obsolete\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 are the continuous current ratings for the relay outputs on the 1761-L10BWB?

A: Operating temperature is rated from 0 to 55 deg C (32 to 131 deg F) when mounted horizontally, but degrades to 0 to 45 deg C (32 to 113 deg F) when mounted vertically due to thermal dissipation constraints.\u003c\/p\u003e\n\u003cp\u003eQ: What memory capacity is available for logic execution in this controller? A: The onboard 1 K EEPROM provides dedicated memory for 737 instruction words, 437 data words, and up to 40 timers without requiring battery power retention.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53136386162968,"sku":"1761-L10BWB","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1761-L10BXB3_Cocoai.jpg?v=1793758734","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1761-l10bwb-micrologix-1000-controller","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
