The part number **M2REB-RD2-R2/UL** refers to a high-quality industrial component, specifically an **Industrial Relay/Base assembly**, typically associated with manufacturers like **IDEC** or specialized industrial automation suppliers. Below is a breakdown of the electronic components and specifications for this part. ### 1. Component Overview The assembly generally consists of a **plug-in relay** and a **DIN-rail mountable socket (base)**. It is designed for switching electrical loads in control panels and automation systems. | Specification | Details | | :--- | :--- | | **Component Type** | Industrial Relay & Base Assembly | | **Configuration** | DPDT (2 Form C) - Double Pole Double Throw | | **Coil Voltage** | Typically 24V DC (Verify specific catalog for variation) | | **Contact Rating** | 10A (General Purpose) | | **Safety Standard** | UL Recognized (indicated by the /UL suffix) | | **Mounting** | 35mm DIN Rail or Surface Mount | --- ### 2. Functional Breakdown The part is divided into two primary electronic sections: #### A. The Relay (M2REB) * **Electromagnetic Coil:** When energized, it creates a magnetic field that pulls the armature to toggle the contacts. * **Contacts:** Silver alloy contacts designed to handle inductive and resistive loads without excessive pitting or welding. * **LED Indicator:** Usually includes a built-in LED to show the status of the coil (on/off). #### B. The Socket/Base (RD2-R2) * **Terminal Blocks:** Screw terminals for secure wiring of inputs and outputs. * **Protection Circuitry:** Often includes a suppression diode or MOV (Metal Oxide Varistor) to protect the driving PLC/Controller from "flyback" voltage spikes when the coil is de-energized. * **Mechanical Clip:** A spring-loaded or plastic lever that locks the relay into the base to prevent vibration-induced loosening. --- ### 3. Connection Pinout (Typical DPDT) For a standard DPDT relay configuration in this series, the terminal layout follows this logic: | Terminal No. | Function | | :--- | :--- | | **13, 14** | Coil (A1, A2) | | **9, 12** | Common (COM) | | **5, 8** | Normally Open (NO) | | **1, 4** | Normally Closed (NC) | --- ### 4. Technical Characteristics * **Response Time:** Approx. 15ms-20ms. * **Dielectric Strength:** 2,000V AC between coil and contacts. * **Electrical Life:** 100,000+ operations at full load. * **Mechanical Life:** 10,000,000+ operations. ---
