Delay Timer Relay Switch Modules, Set of 6 NE555 DC 12V Adjustable 0-10 Seconds
Delay Timer Relay Switch Modules, Set of 6 NE555 DC 12V Adjustable 0-10 Seconds
This set of six delay timer relay switch modules is built around an NE555 chip. A high-precision potentiometer sets the timing, and turning it counterclockwise lengthens the delay within the 0-10 second range. Each module includes a high frequency filter capacitor for stable operation.
After 12V DC power is applied, the relay pulls in and changes state once the delay has elapsed, and it stays in that state while the module remains powered. Input power and relay pull-in indicator lights show the module status. The modules suit vehicle equipment delay circuits as well as electronics learning, product development and graduation design projects.
