Radio Design Labs' ST-LCR1 Logic Controlled Relay is part of the group of products in the STICK-ON series by Radio Design Labs. These products are designed for quick, convenient installation, and reliable operation with a variety of control input options.

Both the ST-LCR1 and ST-LCR2 provide identical dry-switching contacts, LED indicator showing relay activation, and input connections. The difference between the products is that the ST-LCR1 is momentary in operation. When an input control signal is provided, the relay closes; in the absence of an input control signal, the relay is released. The ST-LCR2 contains additional digital flip-flop circuitry, which provides alternate-action. When a momentary control pulse is received, the relay switches on and remains on. When the next momentary pulse is received, the relay returns to the released position.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

The ST-LCR1 is ideally suited to applications where switching contacts need to be added to nearly any type of control signal.

All this is available in the incredible convenience of the RDL STICK-ON Package. They mount right where you need them, or are available with optional rack mounting kit. ST-LCRs are your simple and economical switching solutions!

Control Inputs
Input from other equipment’s open-collector output turns the relay on when pulled to ground (RDL switching STICK-ONs have available open-collector outputs suitable for driving ST-LCR1 and ST-LCR2). Input from remote push-button or switch turn on the relay when that switch is on. Activation is by connecting this input to ground.

The 5 Vdc input accepts 3.5 Vdc to 12 Vdc to turn on the relay. The relay is only on when this control signal iapplied. The 24 Vdc input accepts 12 Vdc to 35 Vdc to activate the control circuit. The relay is only on when this control signal is applied.

Wherever a logic controlled relay is needed, RDL LCRs are the ideal choice. Use RDL LCRs with other RDL RACK-UP®, STICK-ON®, TX™, or FLAT-PAK™ series products as part of a complete audio/video system.
