Featuring 4 normally open contacts and a coil rated at 110\/120V AC, this relay is designed for easy integration on standard 35mm DIN rails. It is a favored choice among panel builders and OEMs due to its compact form, screw terminal connections, and a 10 AMP rating. Its compatibility with top-mounted auxiliary contact blocks allows expansion up to 8 contacts in any combination, supporting complex control schemes as requirements grow. The 700-K40E-D is UL and IEC certified, supporting long operational lifespans (rated for up to 300,000 cycles), which helps reduce maintenance and equipment downtime.\n\n\u003ch2\u003eKey Features of Allen Bradley 700-K40E-D\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e4 normally open base contacts for versatile switching applications\u003c\/li\u003e\n  \u003cli\u003eRated at 10 AMPS for both AC-12 and AC-6 utilization categories\u003c\/li\u003e\n  \u003cli\u003e110V AC (50Hz) \/ 120V AC (60Hz) coil for global voltage compatibility\u003c\/li\u003e\n  \u003cli\u003eScrew terminals enable secure wiring and rapid installation\u003c\/li\u003e\n  \u003cli\u003eDIN rail or base mounting for flexible panel layouts\u003c\/li\u003e\n  \u003cli\u003eExpandable up to 8 poles with auxiliary blocks\u003c\/li\u003e\n  \u003cli\u003eUL, CE, CUL, and IEC certifications ensure compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 700-K40E-D\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eCoil Voltage: 110V AC (50Hz) \/ 120V AC (60Hz)\u003c\/li\u003e\n  \u003cli\u003eContact Configuration: 4 NO (normally open)\u003c\/li\u003e\n  \u003cli\u003eContact Rating: 10A (AC-12, AC-6 utilization categories)\u003c\/li\u003e\n  \u003cli\u003eTerminals: Screw clamp\u003c\/li\u003e\n  \u003cli\u003eMounting: DIN rail (35mm) or direct base\u003c\/li\u003e\n  \u003cli\u003eMax Auxiliary Contacts: 4 additional (up to 8 total contacts)\u003c\/li\u003e\n  \u003cli\u003eCertifications: UL, CE, CUL, IEC\u003c\/li\u003e\n  \u003cli\u003eOperating Cycles: Up to 300,000\u003c\/li\u003e\n  \u003cli\u003eCountry of Origin: Switzerland\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\nAllen Bradley 700-K40E-D relays are widely used for industrial automation, machinery control, and panel building where reliable and repeatable switching is critical. They serve as interface relays between PLC outputs and field devices, enabling the control of motors, lights, solenoids, and contactors. The ability to expand contact sets makes them suitable for custom wiring schemes and signaling applications found in conveyor systems, HVAC controls, material handling, and packaging equipment. Their compact footprint is valuable in dense panels where space optimization is required, and strong certifications mean safe deployment in facilities with rigorous compliance demands. Maintenance teams benefit from the straightforward DIN rail installation and long operational life, reducing overall lifecycle costs in demanding production environments.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/examples-of-industrial-automation-control-systems\" target=\"_blank\"\u003eExamples of Industrial Automation and Control Systems\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-194e-sy\" target=\"_blank\"\u003eAllen Bradley 194E-SY Disconnect Switch for Panel Protection\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1321-3r18-b\" target=\"_blank\"\u003eAllen Bradley 1321-3R18-B Resistor Assembly for Control Panels\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870784176427,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_a15a9d95-68c1-4f68-95a0-319e48ada695.png?v=1723532133","url":"https:\/\/leadtime.ca\/products\/allen-bradley-700-k40e-d","provider":"LEADTIME","version":"1.0","type":"link"}
