The **CL-300-RSC-E-2** is an industrial-grade **Column Light (Signal Tower)** manufactured by Patlite. It is part of the CL30 series, designed specifically for cleanroom environments and equipment status indication. Below is a detailed breakdown of its electronic components and technical specifications. --- ## 1. Electronic Specifications The "E-2" suffix typically denotes the wiring and color configuration (often representing a 2-tier or specific regional wiring standard). | Feature | Specification | | :--- | :--- | | **Rated Voltage** | 24V DC | | **Operating Voltage Range** | 24V DC ± 10% | | **Current Consumption** | ~40mA to 100mA (depending on active tiers) | | **Signal Input** | Dry contact or NPN/PNP Open Collector | | **Light Source** | High-intensity Multi-color LEDs | | **Protection Rating** | IP66, IP67, IP69K (High-pressure washdown) | --- ## 2. Key Electronic Components ### A. LED Engine (Light Emitting Diodes) Unlike traditional bulbs, this unit uses **Surface Mount Device (SMD) LEDs**. * **Efficiency:** Low power draw allows for control directly via PLC (Programmable Logic Controller) without the need for external relays. * **Multi-color capability:** The electronic board is designed to mix Red, Amber, and Green signals within a single tier or across the frosted lens. ### B. Internal Driver Circuitry The internal PCB includes: * **Reverse Polarity Protection:** Prevents damage if the 24V DC leads are accidentally swapped. * **Current Limiters:** Resistors or constant-current drivers ensure the LEDs maintain consistent brightness despite minor voltage fluctuations. * **Transistor Switching:** Internal electronic switches handle the logic for turning specific colors on or off based on the input wires. ### C. Wiring & Interface The unit uses a multi-core cable (typically 300mm to 1000mm length). * **Common Wire:** Usually a single wire for power return. * **Signal Wires:** Individual colored wires corresponding to the light segments. * **Compatibility:** Designed to interface directly with industrial automation controllers (PLCs). --- ## 3. Physical & Environmental Electronics * **Vibration Resistance:** The electronic components are potted or secured to withstand high-vibration industrial machinery (up to 19.6 m/s²). * **Heat Management:** The circular design acts as a passive heat sink for the LEDs, ensuring a long service life (approx. 100,000 hours). * **EMI/EMC Compliance:** Shielded to prevent electromagnetic interference with sensitive cleanroom sensors. --- ## 4. Wiring Diagram Concept *Note: Always refer to the specific manual for wire color coding, as it can vary by region.* ```text [ Power Supply 24V DC ] | +---- [ Red Wire ] -----> (Red LED Circuit) +---- [ Green Wire ] -----> (Green LED Circuit) +---- [ Amber Wire ] -----> (Amber LED Circuit) | [ Common / Ground ] <------------- (Return Path) ``` ---
