Application Analysis
The CDJS18-A excels in applications requiring precise timing control. Its 1-10 minute adjustable delay range makes it ideal for motor sequencing in conveyor systems, where multiple motors need staggered start-up to prevent overload. In HVAC systems, it controls fan delays after burner ignition. For motor control applications, it provides soft-start functionality by delaying contactor engagement, reducing inrush current and mechanical stress on equipment.
Buying Considerations
When selecting the DELIXI CDJS18-A time relay for your application, consider these critical factors:
Voltage Compatibility: Ensure your control circuit matches the AC24V rating. For different voltage requirements, DELIXI offers variants up to AC380V.
Time Range Requirements: The 1-10 minute range suits most industrial applications. For shorter delays (seconds) or longer delays (hours), consider alternative models in the CDJS18 series.
Contact Rating: The 10A contact rating handles most industrial loads, but verify your load current doesn't exceed this specification.
Mounting Configuration: The 35mm DIN rail mounting is standard for industrial panels. Ensure adequate space and proper rail installation.
Environmental Conditions: The IP20 rating provides basic protection against dust and moisture. For harsh environments, consider additional enclosure protection.
Frequently Asked Questions
Q: What is the difference between CDJS18 and CDJS18-A models?
A: The CDJS18-A is specifically an on-delay timer with 1-10 minute range, while standard CDJS18 models may offer different timing functions like interval delay or off-delay with various time ranges.
Q: Can this time relay be used for DC applications?
A: No, the CDJS18-A AC24V is designed specifically for AC control circuits. For DC applications, you would need a DC-rated time relay with appropriate voltage specifications.
Q: How do I adjust the timing on the CDJS18-A?
A> Timing adjustment is typically done via a potentiometer or dial on the front of the unit. Turn the adjustment knob clockwise to increase delay time and counterclockwise to decrease it within the 1-10 minute range.
