The **LCE-1G-R/Q** is part of the LCE series manufactured by **Patlite**. These are signal tower lights (stack lights) commonly used in industrial automation to provide visual status indications for machinery. Below is a detailed breakdown of its electronic components and specifications. --- ### 1. Model Code Breakdown Understanding the specific part number helps identify the electrical configuration: | Component | Code | Meaning | | :--- | :--- | :--- | | **Series** | LCE | 40mm diameter signal tower | | **Tiers** | 1 | Single LED module | | **Mounting** | G | Pole mount with "L" bracket | | **Color** | R | Red LED lens | | **Wiring** | Q | M12 Quick Disconnect (EU standard) | --- ### 2. Core Electronic Components #### A. LED Module (Red) * **Illumination:** High-intensity LEDs arranged in a circular pattern for 360-degree visibility. * **Power Consumption:** Extremely low (approx. 0.7W to 1.2W), reducing the load on the PLC (Programmable Logic Controller) outputs. * **Heat Dissipation:** Designed with a vertical heat-sink arrangement within the lens to ensure long lifespan (rated up to 100,000 hours). #### B. Internal Circuitry * **Internal Rectifier:** Most models include a diode bridge to prevent damage from reverse polarity during installation. * **Current Limiting Resistors:** Integrated into the PCB to protect LEDs from voltage spikes. * **Control Method:** NPN/PNP Open Collector compatible. This allows the light to be driven directly by transistors in most industrial controllers. #### C. Connector (The "Q" Factor) * **Type:** M12 5-pin connector. * **Benefit:** This electronic interface allows for rapid replacement and standardized cabling, minimizing downtime compared to lead-wire versions. --- ### 3. Technical Specifications | Feature | Specification | | :--- | :--- | | **Rated Voltage** | 24V AC/DC | | **Current Consumption** | ~50mA | | **Operating Temp** | -15°C to +40°C | | **Protection Rating** | IP54 (Dust and Splash resistant) | | **Input Logic** | Bi-polar (Works with NPN or PNP) | --- ### 4. Wiring Logic Because this is a single-tier (Red) unit with a connector, the internal electronic wiring usually follows this pin-out logic: ```yaml Pin 1: Brown (Power Supply +24V) Pin 2: White (Not used/Buzzer if applicable) Pin 3: Blue (Common/Ground) Pin 4: Black (Signal Input for Red LED) Pin 5: Gray (Not used) ``` ---
