It provides a timing range of 10 to 180 seconds, making it well suited for sequenced startup routines and timed switching operations where a brief delay between signal input and contact switching is required. The relay features a normally closed (NC) contact form and installs via subbase mount, allowing for clean wiring and straightforward field replacement without disturbing existing terminations. Licensed electricians and HVAC controls technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe PRTB10 is used in commercial and light industrial control panels where pneumatic timing logic governs equipment sequencing. Typical applications include staged HVAC equipment startup, compressor delay-on-start circuits, and fan or pump sequencing systems. Its subbase mounting style is common in relay panel assemblies where modular replacement is a priority. The 2-pin configuration keeps integration straightforward in standard control wiring layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOn-delay timing range of 10 to 180 seconds for flexible sequencing control\u003c\/li\u003e\n  \u003cli\u003eNormally closed (NC) contact form provides fail-safe default state\u003c\/li\u003e\n  \u003cli\u003eSubbase mount design allows relay body replacement without rewiring\u003c\/li\u003e\n  \u003cli\u003e2-pin contact configuration for straightforward panel integration\u003c\/li\u003e\n  \u003cli\u003ePneumatic timing mechanism operates independently of electronic signal fluctuations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for pneumatic time delay relay applications using subbase-mount relay sockets in commercial and industrial control panel assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC controls technician in accordance with applicable NEC requirements. De-energize the control circuit and verify zero voltage at the subbase terminals before removing or seating the relay body. Confirm the subbase socket pin configuration matches the PRTB10 2-pin layout before applying power. Do not exceed the rated timing range when configuring the delay adjustment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Pneumatic Time Delay Relay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTiming Mode\u003c\/strong\u003e: On Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Timing\u003c\/strong\u003e: 10 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Timing\u003c\/strong\u003e: 180 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: NC (Normally Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pins\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Subbase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 39122331\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PRTB10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544174690610,"sku":"PRTB10","price":371.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ff0e961786a4b62be38ed2806e73ea8.jpg?v=1785925216","url":"https:\/\/voomisupply.com\/products\/parker-prtb10-pneumatic-time-delay-relay-subbase-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
