On air compressor systems, time delay relays serve several important functions: they prevent short-cycling on motor restart, allow pressure to equalize across the system before the motor re-engages, and protect the motor from the thermal stress of rapid successive starts. The TD100''s broad voltage range makes it compatible with both single-phase 120V shop setups and 240V compressors without needing a separate part for each voltage.\u003c\/p\u003e\n\u003cp\u003eShort-cycling — where the compressor motor starts, shuts off as the pressure switch trips, and immediately restarts because pressure dropped again — is one of the fastest ways to burn out a motor. A properly set time delay ensures the motor does not restart until enough time has passed for the motor windings to cool and the pressure to stabilize. For 5 HP and larger motors, a 30–60 second restart delay is common practice. The TD100''s 1-to-1023-second range gives you enough adjustment room to handle small single-phase motors through large industrial units.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Range:\u003c\/strong\u003e 18 to 240 volts — covers 120V single-phase and 240V single or three-phase compressor applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelay Range:\u003c\/strong\u003e 1 to 1,023 seconds (approximately 17 minutes maximum) — wide enough for any compressor restart delay application\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Timing:\u003c\/strong\u003e Set the delay at installation to match your motor size and system requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectronic Design:\u003c\/strong\u003e More consistent and reliable than mechanical or pneumatic time delay devices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Protection:\u003c\/strong\u003e Prevents short-cycling that causes premature motor winding failure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressor System Compatible:\u003c\/strong\u003e Works with Cast Air compressor electrical panels and controls\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e TD100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 18–240 Volt AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelay Range:\u003c\/strong\u003e 1–1,023 seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Electronic time delay relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air (Castair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e 2.35\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTypical Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAdding restart delay protection to any Cast Air compressor to prevent short-cycling after the pressure switch trips\u003c\/li\u003e\n\u003cli\u003eMotor protection on 5 HP and larger compressors where rapid restart creates thermal stress on windings\u003c\/li\u003e\n\u003cli\u003eFacilities where the compressed air demand causes the pressure to drop and recover quickly — the TD100 ensures the motor gets adequate cool-down time between starts\u003c\/li\u003e\n\u003cli\u003eReplacing a failed time delay relay in an existing compressor control panel\u003c\/li\u003e\n\u003cli\u003eNew panel builds where time delay relay is specified\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Buy From OEM Diagnostic Tools?\u003c\/h3\u003e\n\u003cp\u003eThe TD100''s wide voltage and timing range makes it a versatile component for many compressor electrical configurations.
