The **W2RS-024-R** is a specific model of a **Miniature Industrial Power Relay**, commonly used in automation, control panels, and PLC interfacing. Below is a detailed breakdown of its electronic specifications and internal parts. --- ### 1. General Specifications The W2RS series is typically characterized by its slim profile and high-density mounting capability. | Feature | Specification | | :--- | :--- | | **Model** | W2RS-024-R | | **Coil Voltage** | 24V DC | | **Contact Arrangement** | 2C (DPDT - Double Pole Double Throw) | | **Mounting Type** | DIN Rail / Socket Mount | | **Terminal Type** | Screw or Push-in (depending on base) | --- ### 2. Internal Electronic Components The device consists of several critical components that allow it to function as an electrically operated switch: #### A. The Electromagnetic Coil * **Voltage:** 24V DC. * **Function:** When current flows through this copper coil, it creates a magnetic field that pulls the armature down, changing the state of the contacts. * **Power Consumption:** Designed for low power consumption to allow direct control from PLC outputs. #### B. Contact System (2C / DPDT) * **Material:** Usually Silver Alloy (AgNi or AgSnO2) for high conductivity and resistance to arcing. * **Configuration:** 2 Change-over contacts. This means it can control two separate circuits simultaneously. * **Rating:** Typically rated for 5A to 8A at 250V AC / 30V DC. #### C. Protection & Indicator Circuits Most "R" suffix models in this series include: * **LED Indicator:** A small Green or Red LED wired in parallel with the coil to provide visual status of whether the relay is energized. * **Freewheeling Diode (Flyback Diode):** Integrated to protect the driving circuit (like a PLC) from back-EMF spikes when the coil is de-energized. --- ### 3. Physical Layout and Construction 1. **Transparent Housing:** Allows for visual inspection of contact wear or carbon buildup without disassembling the unit. 2. **Manual Test Button:** (Optional on some variants) A small lever to manually toggle the contacts for troubleshooting. 3. **Gold Plating:** Some "R" variants feature gold-clad contacts for switching very low-level signals (dry circuits) to prevent oxidation. --- ### 4. Typical Wiring Diagram The W2RS-024-R follows standard industrial pinouts: ```text Coil Terminals: (+) Pin 14 (-) Pin 13 Contact Terminals (DPDT): Common: 9, 12 Normally Closed (NC): 1, 4 Normally Open (NO): 5, 8 ``` ---
