CPM014 - Vox Controlled Relay Switch Module with Microphone

The CPM014 is a pre-built Vox Controlled Relay Switch Module with Microphone. This non-latching relay switch will switch the relay on in response to a user-adjustable audio input signal level . The relay turns off when the sound level falls below the trigger threshold.

Separate microphone board included. Adjustable trigger sensitivity. LED status indicator. Reverse polarity protection. Output to a 5A rated relay.

Operating voltage is 9-15V dc power supply (for example our CFE002 or PSU446).

All modules are supplied fully assembled and tested so you only need to make the necessary connections.
