The **LCE-12-R** is an electronic component manufactured by **Patlite Corporation**. It belongs to the LCE series of LED Signal Towers, specifically designed for industrial machinery to provide visual status indications. Below is an explanation of its electronic specifications and parts. --- ### 1. Model Breakdown The model name "LCE-12-R" can be broken down to understand its core electronic configuration: | Part Segment | Meaning | Specification | | :--- | :--- | :--- | | **LCE** | Series Name | 40mm Diameter LED Signal Tower | | **1** | Tier Count | 1-tier (Single light module) | | **2** | Voltage | 24V AC/DC | | **R** | Color | Red LED | --- ### 2. Key Electronic Specifications The internal circuitry is designed for low power consumption and durability in industrial environments. * **Rated Voltage:** 24V AC/DC (Standard for industrial PLC control systems). * **Operating Voltage Range:** 21.6V to 26.4V DC / 21.6V to 26.4V AC. * **Current Consumption:** Approximately **30mA to 50mA** (Red LED tier). * **Light Source:** High-intensity LEDs (Light Emitting Diodes). * **Operating Temperature:** -15°C to +40°C. --- ### 3. Internal Components and Construction The LCE-12-R is composed of several critical electronic and mechanical parts: #### A. LED Array The core light source consists of multiple surface-mount LEDs arranged on a circular PCB. This array is designed for 360-degree visibility. #### B. Internal PCB (Circuit Board) The base contains a small PCB that acts as a voltage regulator and driver. - **Resistors/Diodes:** Used to drop the voltage to the level required by the LEDs and to prevent damage from reverse polarity (in DC mode). - **Wiring Interface:** Leads are color-coded for easy installation (typically Red for the light, and Yellow/Black for common, depending on the wiring logic). #### C. Wiring Logic (Open Collector) The unit is compatible with **NPN or PNP open collector** transistors. This allows a PLC (Programmable Logic Controller) to trigger the light directly without the need for additional mechanical relays. #### D. Physical Housing (Optical) - **Lens:** Made of heat-resistant and shock-resistant polycarbonate resin. The prism-cut design enhances light diffusion. - **Base:** Usually made of ABS resin for high vibration resistance. --- ### 4. Wiring Diagram Overview While specific lead colors can vary by manufacturing year, the standard logic is: ```yaml Red Wire: Connect to V+ (through switch/PLC) Yellow/Gray Wire: Common Line Internal Protection: Built-in surge suppression ``` ---
