Choose the Audio Relay with the Correct Release Time

The ST-VOX1 Voice Operated Relay can be actuated by an unbalanced mic or line level source. It is primarily used in intercom and talkback applications where a fast contact release time (adjustable 70 to 260 ms) is desired. In applications where longer release times are desired we suggest the use of ST-ACR Series Audio Controlled Relays . The ST-ACR1 and ST-ACR1M have adjustable release times of ½ to 5 seconds. The ST-ACR2 release time is adjustable from 5 to 50 seconds.
