The **W2RS-613-R** is a specific model of a **Miniature Intermediate Power Relay**, typically manufactured by companies like **Wago** or **Dinkle** (often associated with interface modules). It is designed to bridge the gap between low-power control signals (like those from a PLC) and higher-power loads. --- ### 1. Technical Specifications The "613" designation usually refers to the internal relay configuration and voltage ratings. Below are the typical electronic specifications for this part: | Feature | Specification | | :--- | :--- | | **Relay Type** | Electromechanical Relay | | **Contact Configuration** | 1 Changeover (SPDT - Single Pole Double Throw) | | **Input (Coil) Voltage** | 24V DC (Common for this series) | | **Max Switching Voltage** | 250V AC / 30V DC | | **Rated Current** | 6A to 10A (Depending on specific load type) | | **Mounting Type** | DIN Rail (35mm) via Socket | | **Connection Technology** | Push-in or Screw Terminals | --- ### 2. Internal Electronic Components The device is more than just a mechanical switch; it contains several electronic safety and functional parts inside the housing: * **The Coil (Inductor):** When energized with 24V DC, it creates a magnetic field to pull the physical contacts together. * **The Armature/Contacts:** Silver Alloy (AgSnO2) is typically used for the contact points to ensure high conductivity and resistance to "welding" under load. * **Protection Diode (Flyback Diode):** Most "R" suffix models include an integrated freewheeling diode across the coil to protect the driving PLC/Controller from voltage spikes when the relay is turned off. * **LED Status Indicator:** A built-in green or red LED provides visual confirmation that the control circuit is active. --- ### 3. Wiring Diagram Logic The terminal numbering follows standard industrial relay patterns: ```text Input Side (Control): A1 (+) : Positive 24V DC A2 (-) : Negative / Ground Output Side (Load): 11 (COM) : Common Terminal 12 (NC) : Normally Closed 14 (NO) : Normally Open ``` --- ### 4. Key Applications * **Signal Isolation:** Protecting sensitive PLC outputs from high-voltage surges in the field. * **Current Amplification:** Using a small 20mA control signal to switch a 6A motor or heater. * **Voltage Conversion:** Controlling a 230V AC device using a 24V DC control system.
