Reliable Power-Off Delay Timing for Industrial Control Sequences
The H3DT-HBL AC-DC24-48V is used where controlled delay after power removal is required to stabilize machine behavior or complete orderly shutdown steps. It helps engineers implement repeatable timing logic in panel-based automation systems without complex programming overhead. This timer is suitable for conveyor systems, auxiliary equipment sequencing, and interlock timing chains in both new and retrofit control cabinets.
Typical Applications
- Delaying fan or auxiliary stop after main power removal
- Sequencing conveyor stop timing to avoid jams
- Implementing orderly shutdown in machine interlock chains
- Timing off-delay for pneumatic or hydraulic support circuits
- Retrofitting relay-timer logic in legacy control panels
- Standardizing hardwired off-delay behavior across OEM builds
Buying Checklist
- Simple and reliable off-delay timing without complex PLC code
- Wide supply range supports mixed-panel design standards
- Improves sequence consistency during stop and shutdown events
- Practical for both new builds and maintenance replacements
- Useful component for robust panel-level control strategies

Frequently Asked Questions
What is power-off delay and when do I need it?
Power-off delay keeps output energized for set time AFTER power is removed. Applications: cooling fan run-on (prevent overheating), lubrication pump after shutdown, purge cycles, safe shutdown sequences.
How does timer operate without power?
Internal capacitor stores energy when powered. When power is removed, capacitor discharges through timing circuit, keeping relay energized for set delay. No battery required.
What's the maximum delay time?
0.5 to 10 seconds. For longer delays (minutes), use H3DK with battery backup or PLC with UPS. Power-off delay is typically for short safety/process delays.
Can I adjust the delay time?
Yes, front-panel potentiometer adjusts from 0.5 to 10 seconds. Use small screwdriver. Lock with seal if adjustment should be tamper-proof.
