220V relay board, power on, time delay, circuit module, D1B5

Feature Highlights: 1. Instant Power Delivery – Once connected to 220V, the output voltage is supplied to the load immediately. The load is automatically cut off when the set delay time ends. 2. Simple Direct Connection – Direct 220V input and output. Works easily with external power lines, loads, and control buttons. 3. High-Capacity Relay – Uses a quality original loose relay with a switching current up to 10A, suitable for loads up to 2200W. 4. Flexible Contact Options – Includes both normally open and normally closed contacts, allowing wiring according to your needs. 5. Adjustable Timing – Delay time can be continuously adjusted from 1 second to 60 seconds to match various application requirements. 6. Stable & Reliable Circuit – Built with an NE555 monostable circuit for accurate timing, and an RC step-down power supply with an X2 safety capacitor, a 3W high-power resistor, and a 470uF filter capacitor for steady operation. 7. Durable & Safe Design – FR-4 fiberglass board reduces leakage risk and withstands various environmental conditions and temperatures. 8. Easy Installation – Compact board size (65x38 mm) with 4 mounting holes for convenient integration into your projects.
