The **LCE-1A-R/Q** refers to a high-quality, stackable signal tower light manufactured by **Patlite**. These devices are primarily used in industrial environments to provide visual status indications for machinery and automated processes. --- ### 1. Technical Specifications The LCE series is known for its compact design and high-visibility LED technology. Below are the key electronic and physical specifications: | Feature | Specification | | :--- | :--- | | **Model** | LCE-1A-R/Q | | **Voltage** | 24V AC/DC | | **Current Consumption** | Approx. 45mA - 55mA | | **Tier Count** | 1 Tier (Red LED) | | **Mounting Style** | Pole Mount / Direct Mount (depending on suffix) | | **Protection Rating** | IP54 (standard) | | **Lighting Source** | High-intensity LED | --- ### 2. Key Electronic Components The LCE-1A-R/Q is comprised of several critical electronic subsystems: #### A. LED Array (The "R" Suffix) The **"R"** stands for **Red**. - **Efficiency:** The light uses low-power LEDs that provide high brightness while maintaining a long service life (typically over 100,000 hours). - **Optics:** The lens features a "prism-cut" design that enhances light diffusion, ensuring the signal is visible from 360 degrees. #### B. Internal Circuitry - **Current Regulation:** Internal resistors and diodes protect the LEDs from voltage spikes and ensure consistent brightness across the 24V range. - **Wiring Logic:** The unit uses a standard wire-lead system where specific colors correspond to the tiers and the common line. #### C. Control Interface (The "Q" Suffix) The **"Q"** usually denotes the specific **Wiring/Connection type** (often M12 Quick Disconnect or specific lead wire configurations depending on the regional catalog). - **PLC Compatibility:** The device is designed for an **Open Collector** interface, meaning it can be driven directly by NPN or PNP outputs from a Programmable Logic Controller (PLC). --- ### 3. Wiring Diagram Overview While specific wire colors should always be verified with the included manual, the standard electronic interface follows this logic: ```yaml Red Wire: Red LED Module (Signal) Yellow Wire: (Usually N/A for 1-tier, or used for Buzzer in other models) Grey Wire: Common (usually COM + for PNP, COM - for NPN) ``` --- ### 4. Application Use-Case The **LCE-1A-R** is typically used as a **Stop** or **Error** indicator. Because it is a single-tier (1-tier) unit, it is most often used for: 1. **Critical Alarm:** To notify an operator that a machine has stopped. 2. **Safety Boundary:** To indicate that a zone is currently "Hot" or dangerous. 3. **Status Confirmation:** Integrated into an automated assembly line to show "Not Ready" status.
