The **LR5-302WEBW-RYG** is a specific model of the **Patlite LR5 Series** Signal Tower. This is a modular, 50mm diameter LED stack light designed for industrial automation and status signaling. Below is a detailed breakdown of its electronic components and technical specifications. --- ### 1. Model Code Breakdown Understanding the specific parts begins with decoding the model number: | Code | Specification | Description | | :--- | :--- | :--- | | **LR5** | Series | 50mm Diameter LED Signal Tower | | **3** | Tiers | 3 Stacked LED Modules | | **02** | Voltage | 24V DC Rated Voltage | | **WEB** | Mounting/Wiring | Direct Mount with Cable (W), Off-white body (E), Flashing/Buzzer (B) | | **W** | Lens Type | Multi-color or Cylindrical Lens | | **RYG** | Colors | Red, Amber (Yellow), Green | --- ### 2. Electronic Component Specifications #### A. Lighting Unit (LEDs) * **Technology:** High-intensity surface-mount LEDs. * **Optics:** A specialized "inner lens" design that refracts light 360 degrees, ensuring visibility from long distances and all angles. * **Current Consumption:** Typically **45mA** per LED module. #### B. Sound Module (Buzzer) * **Type:** Piezoelectric transducer. * **Sound Pressure:** 85dB at 1 meter. * **Control:** Integrated into the base; can be toggled via specific wire inputs. * **Current Consumption:** **40mA** when active. #### C. Control Electronics * **Input Logic:** Compatible with NPN and PNP (Open Collector) transistors. * **Flash Circuitry:** Internal oscillator for the "Flashing" function (approx. 60 flashes per minute). * **Protection:** IP65 rated (when mounted properly), meaning the electronics are sealed against dust and water jets. --- ### 3. Wiring and Electrical Interface The device uses a multi-core cable. Each wire color corresponds to a specific electronic function: | Wire Color | Function | Description | | :--- | :--- | :--- | | **Red** | Red LED Module | Signal to light the top tier | | **Orange** | Amber LED Module | Signal to light the middle tier | | **Green** | Green LED Module | Signal to light the bottom tier | | **Purple** | Buzzer | Activates the audible alarm | | **Blue** | Flashing | Common for activating flash mode | | **Yellow** | Common | Power return / Common line | --- ### 4. Key Physical/Technical Characteristics * **Operating Voltage:** 24V DC (allows for +/- 10% fluctuation). * **Connection Method:** Lead wires (discrete wire connection). * **Insulation Resistance:** 1MΩ or more at 500V DC. * **Ambient Temp Range:** -20°C to +50°C.
