## Schneider Electric RXM2AB1F7: Product Overview The **RXM2AB1F7** is a miniature plug-in electromechanical relay from the **Zelio Relay (Harmony)** range by Schneider Electric. It is widely used in industrial automation for switching electrical loads and providing electrical isolation between control circuits and power circuits. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | Miniature Plug-in Relay | | **Contact Composition** | 2 C/O (Double Pole Double Throw - DPDT) | | **Control Circuit Voltage** | 120 V AC | | **Thermal Current (Ith)** | 12 A (at -40…55 °C) | | **Rated Operational Current** | 12 A at 250 V AC / 28 V DC | | **Status LED** | Included (Indicates coil energization) | | **Control Type** | Lockable test button | | **Shape of Pin** | Flat (Plug-in style) | --- ### 2. Major Electronic & Mechanical Components The RXM2AB1F7 consists of several critical internal parts that facilitate its operation: * **Electromagnetic Coil:** Wound for **120V AC**. When energized, it creates a magnetic field that pulls the armature. * **Armature & Spring:** The armature moves when the magnetic field is present. A return spring ensures the contacts revert to their original state (NC) once power is removed. * **Contacts (AgNi):** Silver Nickel alloy contacts provide high durability and resistance to electrical arcing. * **Mechanical Indicator:** A small mechanical flag that shows whether the relay is active. * **Lockable Test Button:** A blue button (for AC coils) that allows manual overriding of the contacts for testing without powering the coil. * **LED Indicator:** A built-in light-emitting diode that glows when the coil is energized, aiding in troubleshooting. --- ### 3. Wiring and Contact Arrangement The relay features a **2 C/O (Change-Over)** configuration, meaning it has two independent sets of contacts. Each set contains: 1. **Common (COM)** 2. **Normally Closed (NC)** 3. **Normally Open (NO)** #### Connection Diagram Logic * **Coil Terminals (A1, A2):** Connected to the 120V AC control source. * **Contact Terminals:** Used to break or complete the circuit for the load (e.g., motors, lights, or solenoids). --- ### 4. Mounting and Compatibility This relay is typically used with a **RXZE** series socket (base). It allows for easy DIN rail mounting and simplifies replacement without needing to rewire the entire circuit.
