Radio Design Labs Time Delay Relays

Overview

Radio Design Labs ST-ACR1 is a Stick-On series line-level audio controlled relay that senses line-level signals and switches equipment using DPDT contacts. The unit provides adjustable input sensitivity from -30 to 0 dBu with a threshold LED and a DELAY control that sets relay release from 0.5 to 5 seconds. It accepts balanced or unbalanced inputs (10 k9;), features an open-collector slave output, and requires 24 to 33 Vdc at 50 mA.
