It supports both Delay-On-Make and Delay-On-Break timing functions in a single encapsulated unit, with an adjustable timing range of 1 to 45 seconds. The microcontroller-based design eliminates moving parts, reducing the risk of arcing and mechanical wear over time. The fully encapsulated housing protects internal components against shock, vibration, and humidity. Licensed HVAC technicians and controls specialists install this relay as part of sequencing and load management strategies in heating and cooling systems.\u003c\/p\u003e\n\u003cp\u003eThe CT1S45 is suited for residential and light commercial HVAC applications where precise timing control is required during system startup or shutdown sequences. It supports interconnection with other CT-series modules, allowing multiple relays to be combined for sequencing multiple loads on or off in a defined order. This makes it practical for staged heating systems, multi-zone cooling setups, and any application where load staging improves system efficiency and reduces electrical stress at startup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDelay-On-Make and Delay-On-Break functions combined in one unit\u003c\/li\u003e\n  \u003cli\u003eAdjustable timing range of 1 to 45 seconds\u003c\/li\u003e\n  \u003cli\u003eFully solid-state and encapsulated construction with no moving parts\u003c\/li\u003e\n  \u003cli\u003eEncapsulated housing resists shock, vibration, and humidity\u003c\/li\u003e\n  \u003cli\u003eInterconnects with other CT-series modules for load sequencing\u003c\/li\u003e\n  \u003cli\u003eUL, CSA, and CE listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement time delay relay for 24-volt AC HVAC control circuits.

De-energize the control circuit and confirm power is off before removing or installing the relay. The surface-mount configuration should be secured to a stable panel or DIN rail surface per manufacturer guidance. Follow all applicable local codes and the National Electrical Code when wiring low-voltage control circuits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Voltage Rating\u003c\/strong\u003e: 24 volts AC, 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Current Rating\u003c\/strong\u003e: 0.75 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTiming Range\u003c\/strong\u003e: 1 to 45 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTiming Mode\u003c\/strong\u003e: Delay-On-Make \/ Delay-On-Break\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Type\u003c\/strong\u003e: AC Operated, Microcontroller\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Surface Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL, CSA, CE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED AIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CT1S45\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED AIR","offers":[{"title":"Default Title","offer_id":51284027212082,"sku":"CT1S45","price":53.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277534.jpg?v=1781066498","url":"https:\/\/voomisupply.com\/products\/allied-air-ct1s45-time-delay-relay-24v-0-75a-1-45-sec","provider":"Voomi Supply","version":"1.0","type":"link"}
