Cebek PM-15 sound activated relay switch board module. 1 second to 4 minute on-timer or latching mains rated relay output. Turns on in response to user-adjustable sound level. Microphone mounted on separate board with 10cm cable.
In Delay Timer mode, the relay turns on when triggered by sound and turns off after the user set delay time has elapsed. If sound is still present, there will be a short pause (about 1 second) before the relay is reactivated and a fresh delay countdown begins.
The Cebek PM-15 is less sensitive than our 3126 sound activated board so may be more suited to applications where a higher sound level is preferred to activate the relay.
Supplied fully assembled and tested so you only need to make the necessary connections.
