The **M2PHS2L-23-R2/CE** is a specific model within the series of industrial multi-stack LED signal towers (often called stack lights) manufactured by companies like **Menics**. These are used in automation and manufacturing to provide visual and audible status indications. --- ## 1. Breakdown of Specifications | Feature | Specification | | :--- | :--- | | **Model Series** | M2PH (Multi-stack LED Signal Tower) | | **Mounting Style** | Pole Mount (indicated by 'P') | | **Diameter** | 56mm (Standard for the M2 series) | | **Light Tiers** | 2 Tiers (indicated by '2' after the series) | | **Light Functions** | Steady and Flashing (indicated by 'S') | | **Input Voltage** | 24V AC/DC (indicated by '23') | | **Lens Colors** | Red and Green (indicated by 'R2' pattern) | | **Sound Option** | Includes an internal Buzzer/Electronic Alarm (indicated by 'L') | | **Certification** | CE (European Conformity) | --- ## 2. Key Electronic Components ### LED Array (Illumination) Each tier contains a high-intensity LED array. Unlike incandescent bulbs, these LEDs have a lifespan of approximately 50,000 hours and are resistant to vibrations found in industrial machinery. ### Integrated Control Circuit Inside the base of the unit, there is a control PCB (Printed Circuit Board) responsible for: * **Voltage Regulation:** Converting the 24V input into the correct current for the LEDs. * **Flash Generation:** A timing circuit (often using a 555 timer or a small microcontroller) that creates the "Flashing" effect when that specific wire is energized. * **Logic Isolation:** Preventing "ghosting" or backfeed between the different color tiers. ### Electronic Buzzer (The 'L' Component) The "L" designation indicates a built-in piezo-electronic buzzer. * **Decibel Level:** Typically 80~90 dB at 1 meter. * **Wiring:** It usually has a dedicated wire, allowing it to be synced with the Red light (for alarms) or used independently. ### Wiring Configuration The unit typically uses a color-coded lead wire system: ```text - Red Wire: Red Light Tier - Green Wire: Green Light Tier - Yellow/Orange: Buzzer Control - Blue/White: Common Line (Neutral/GND) - Gray: Flash Control (depending on specific sub-model wiring) ``` --- ## 3. Electrical Requirements | Parameter | Value | | :--- | :--- | | **Input Voltage** | 24V AC/DC (±10%) | | **Current Consumption** | ~50-100mA per tier | | **Buzzer Current** | ~30mA | | **Temperature Range** | -20°C to +50°C | | **Protection Rating** | IP65 (Dust tight/Water jets) |
