RDL STLCR1H Logic Controlled Relay, Momentary

Radio Design Labs' 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.

Features:

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

Specifications:

• Control Inputs:
  • -SECONDARY terminalused as an input from remote push-button or switch turns on relay when thatswitch is on. Activation is by connecting this input to Ground. Input fromother equipment’s open-collector output turns relay on when open-collector ison.
  • NOTE: RDL switchingSTICK-ONs® have open-collector outputs suitablefor driving an ST-LCR1H.
  • 5V+ accepts 3.5to 12 Vdc to turn on relay. Relay is on only when this control signal isapplied.
  • 24V+ accepts 12 to 35 Vdc to turn on relay. Relay is ononly when this control signal is applied.
• Control Output: SECONDARY terminal open-collector @ 25 mA suitable to drive indicators or secondary LCRs
• Switching Contacts: Double-pole, double-throw
• Maximum Switching Power: 60 W (220 Vdc, 125 Vac, 2A)
• Power Requirement: GROUND-REFERENCED, 24 to 33 Vdc @ 50 mA*
  • *Assumes 20 mA max load at SECONDARY output
