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.

• Switching of Speaker Lines
• Control from Switch or Logic Circuits
• DPDT Switching Contacts
• Open-Collector Switching
• 8 Amp Relay Contacts

• 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.
