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 Ω, 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.
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 switchingSTICK‑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:
