The ST-LCR1H provides dry-switching contacts for high power switching, an LED indicator showing relay activation, and input connections. Switching contacts are suited to switching many 8 ohm, 70.7 V or 100 V speaker lines.
The relay closes when an input signal is applied. The relay releases when the input signal is removed. The ST-LCR1H is ideally suited to applications where high power switching contacts need to be added to nearly any type of control signal. The relay may be activated from any of 3 input signals: 5 Vdc, 24 Vdc, or open-collector.
Use the ST-LCR1H individually, or combine it with other RDL® products as part of a complete audio/video system.

Width:
3 in
Control Inputs:
SLAVE terminal used as an input from remote push-button or switch turns on relay when that switch is on. Activation is by connecting this input to Ground. Input from other equipment’s open-collector output turns relay on when open-collector is on. Note: RDL switching STICK-ONs® have open-collector outputs suitable for driving an ST-LCR1H. 5V+ accepts 3.5 to 12 Vdc to turn on relay. Relay is on only when this control signal is applied. 24V+ accepts 12 to 35 Vdc to turn on relay. Relay is on only when this control signal is applied.
Control Output:
SLAVE terminal open-collector @ 25 mA suitable to drive indicators or slave LCRs
Switching Contacts:
Double-pole, double-throw
Maximum Switching Power:
60 W (220 Vdc, 125 Vac, 2A)
