Operating across flexible input limits of 24-240 VAC (50\/60 Hz) and 24-48 VDC, this specialized timing unit initiates an adjustable 0.5 to 10 s single-shot duration upon receiving an incoming control trigger. Internal SPDT changeover contacts deliver precise circuit isolation and sequencing capability, while its EX rating permits installation in hazardous industrial areas.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cp\u003eThe catalog number structure for the Allen-Bradley 700-FS series defines functional features, timing ranges, coil control voltages, and special environmental certifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e700-FS\u003c\/strong\u003e: Base series designation for industrial high-performance IEC timing relays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eK\u003c\/strong\u003e: Functional mode code indicating One-Shot \/ Watchdog (pulse-controlled) timing action.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\u003c\/strong\u003e: Time scale range code specifying adjustable timing from 0.5 to 10 s.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC\u003c\/strong\u003e: Contact output configuration specifying 1 Changeover Contact (SPDT).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eU23\u003c\/strong\u003e: Wide-range control supply rating covering 24-240 VAC (50\/60 Hz) and 24-48 VDC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEX\u003c\/strong\u003e: Hazardous location protection certification code for ATEX\/IECEx hazardous areas.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHardware Specifications\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\u003e700-FSK3CU23-EX\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\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.10 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard 22.5 mm DIN-rail Enclosure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24-240 VAC \/ 24-48 VDC Input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTiming Function\u003c\/td\u003e\n\u003ctd\u003eOne-Shot \/ Watchdog (Pulse-Controlled)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdjustable Range\u003c\/td\u003e\n\u003ctd\u003e0.5 to 10 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact Configuration\u003c\/td\u003e\n\u003ctd\u003e1 SPDT (1 C\/O Contact)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVibration Resistance\u003c\/td\u003e\n\u003ctd\u003e10-500 Hz, 4 g per IEC 60068-2-6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN Rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eAllen-Bradley Industrial Control \u0026amp; Bus Architecture\u003c\/h3\u003e\n\u003cp\u003eAllen-Bradley control components within the 700-FS product line offer fast backplane bus communication velocity Licences and seamless connectivity across EtherNet\/IP deterministic networks. High I\/O density scaling allows dense mounting arrangements inside remote terminal cabinets without generating signal cross-talk or inductive feedback. Furthermore, firmware flash compatibility across Rockwell Automation platforms ensures that internal relay status monitoring interacts directly with CompactLogix and ControlLogix PLC racks without signal degradation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does a pulse-controlled One-Shot function differ from a standard On-Delay timing sequence?\u003c\/p\u003e\n\u003cp\u003eA: A One-Shot relay closes its output contact immediately upon receiving a control pulse and holds it closed for the preset duration (0.5 to 10 s) regardless of input signal persistence. An On-Delay relay waits for the timer to elapse before closing its contacts.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 700-FSK3CU23-EX be installed in high-vibration machinery control panels?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The hardware is tested and rated to IEC 60068-2-6 standards for vibration resistance up to 4 g over 10-500 Hz, preventing contact chatter and accidental relay tripping under heavy mechanical oscillation.\u003c\/p\u003e\n\u003cp\u003eQ: What is the recommended functional alternative if this specific EX model is unavailable?\u003c\/p\u003e\n\u003cp\u003eA: The functional replacement specified by Rockwell Automation is model 700-FSK6UU23-EX, which offers equivalent one-shot logic and control voltage ranges, though wiring terminal positions and physical depth dimensions may vary slightly.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the relay vertically onto a standard 35 mm DIN rail inside a rated panel enclosure. Ensure the rail latching mechanism fully locks into place to prevent movement during vibration exposure. Leave at least 10 mm of lateral spacing between adjacent heat-generating components to maintain proper convective cooling across the module housing.\u003c\/p\u003e\n\u003cp\u003eStrip control wiring to 6 mm and secure conductor leads into screw terminals using a calibrated torque screwdriver set to 0.5 to 0.8 Nm. Route AC supply conductors and low-voltage DC trigger lines through separate cable conduits to eliminate electromagnetic noise coupling. Connect the external shielding of control lines to a single-point low-impedance earth ground stud within the main cabinet enclosure before applying power.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43914617028707,"sku":"700-FSK3CU23-EX","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/924.jpg?v=1791619166","url":"https:\/\/www.autocontrolglobal.com\/products\/allen-bradley-700-fsk3cu23-ex-700-fs-one-shot-timing-relay","provider":"AutoControl Global","version":"1.0","type":"link"}
