Overview
This is a bundle consisting of two parts both from Radio Design Labs, an ST-LCR1 Relay Module and a PS-24A power supply.
The ST-LCR1 provides double-pole, double-throw dry switching contacts and LED indicator for relay closure. It provides momentary operation and is ideally suited where additional switching contacts are needed to be added to nearly any type of control signal. It is used in telephone applications for controlling external page zones. Included are double sided tape and adhesive velcro mounting options.
- A DPDT switching relay
- Control from switch, button, or logic circuits
- Works as slave relay to add more contacts
The PS-24A is a 24 VDC power supply, 400 mA.

Specifications - ST-LCR1
- The SLAVE Input from a remote push-button or switch turns on the relay when that switch is closed. Activation is by connecting this input to Ground.
- The 5 volt input accepts 3.5 to 12 Vdc to turn on the relay. The relay is on only when this control signal is applied.
- The 24 volt input accepts 12 to 35 Vdc to turn on the relay. The relay is on only when this control signal is applied.
- Outputs: Open-collector @ 100 mA suitable to drive indicators or (slave) LCRs.
