Combining an internal 120\/240 VAC line power supply, central processor, and fixed I\/O layout in a single housing, the unit features 24 VDC sourcing inputs alongside 16 DC sinking outputs. Its integrated architecture simplifies panel wiring and provides reliable control without requiring a separate backplane chassis.\u003c\/p\u003e\n\u003ch3\u003eIntegrated I\/O and Control Capabilities\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1747-L40L\u003c\/strong\u003e incorporates 40 embedded I\/O channels. The input section consists of 24 24 VDC sourcing input points, which interface with sinking field devices. The output section provides 16 24 VDC sinking transistor outputs, enabling rapid switching and solid-state actuation for low-power DC loads.\u003c\/p\u003e\n\u003ch3\u003ePower Line and Hardware Architecture\u003c\/h3\u003e\n\u003cp\u003eEquipped with an internal AC power supply, the controller accepts a line voltage input of 120\/240 VAC. The fixed hardware design houses the power conversion circuit, memory structure, processor engine, and terminal blocks within a unified, panel-mounted enclosure, eliminating the need for modular chassis assemblies.\u003c\/p\u003e\n\u003ch3\u003eTechnical Parameters\u003c\/h3\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\u003e1747-L40L\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\u003eController Type\u003c\/td\u003e\n\u003ctd\u003eSLC 500 Fixed Hardware Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Embedded I\/O\u003c\/td\u003e\n\u003ctd\u003e40 points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Points\u003c\/td\u003e\n\u003ctd\u003e24 points, 24 VDC Sourcing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Points\u003c\/td\u003e\n\u003ctd\u003e16 points, 24 VDC Transistor Sinking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine Operating Voltage\u003c\/td\u003e\n\u003ctd\u003e120\/240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Indicator\u003c\/td\u003e\n\u003ctd\u003eDiscontinued by Manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3.22 lbs\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 input type is integrated into the 1747-L40L controller?A: The controller features 24 VDC sourcing inputs, which require connection to sinking sensor or switch outputs.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 1747-L40L require a separate rack chassis or power supply?
