Product Details:
Accepts balanced or unbalanced input, and provides a DPDT relay output when the presence of an audio signal is detected. It is perfect when adding "audio-power-on" capability to existing equipment. Because the relay utilizes NO and NC contacts, it may also be used in "silence sensing" applications. Trigger threshold is adjustable from -30dBu~0dBu. Adjustable, 5~50 second, off delay sets the time required to for the relay to release when the audio drops below threshold. A 50mA open-collector output is also provided to drive a slave relay or indicator LED. |
|
Features:
•Contact rating: 2A, 250VAC
•Input impedance: 10Kohm
•Power requirement: 24~33VDC, 50mA, ground referenced
