Description
- High-impedance bridging input connects across any audio line
- Input may be connected to either balanced or unbalanced sources
- Multi-turn sensitivity adjustment permits precise threshold setting
- Multi-turn DELAY control adjusts relay release delay
- Band-pass filtering yields triggering on characteristic audio spectrum
- SLAVE terminal may also be used to trigger the control inputs on various other RDL Modules
- SLAVE terminal may be used with remote switch to manually override the control circuit and turn on the relay
- SLAVE open-collector terminal allows additional relays to be added for more contacts
- (RDL's ST-LCR1 or ST-LCR2)
