The **RXM2AB2F7** is a professional-grade miniature relay part of the **Zelio Relay** range manufactured by **Schneider Electric**. It is widely used in industrial control systems for switching electrical loads. --- ## 1. Technical Specifications The part number itself defines the core characteristics of the device. Below is a breakdown of its technical profile: | Feature | Specification | | :--- | :--- | | **Product Type** | Miniature Plug-in Relay | | **Coil Voltage** | 120 V AC | | **Contact Configuration** | 2 C/O (DPDT - Double Pole Double Throw) | | **Rated Current ($I_n$)** | 12 A | | **Control Type** | Lockable test button | | **Status LED** | Included (indicates coil energization) | | **Pin Shape** | Flat (Faston type) | --- ## 2. Key Components and Features The RXM2AB2F7 consists of several critical electronic and mechanical sub-parts: ### A. The Coil (Electromagnet) * **Operating Voltage:** 120V AC, 50/60 Hz. * **Function:** When energized, it creates a magnetic field that moves the armature to switch the contacts. * **Power Consumption:** Typically around 1.2 VA. ### B. The Contact System * **Material:** Silver Alloy (AgNi). This provides a balance between conductivity and resistance to "pitting" or welding under load. * **Capacity:** It can handle up to 12A at 250V AC or 28V DC (Resistive load). ### C. Human-Machine Interface (HMI) * **Mechanical Indicator:** A small orange flag that shows if the relay is mechanically engaged. * **LED Indicator:** A green LED that confirms electrical power is reaching the coil. * **Test Button:** A turquoise button that allows manual forced activation of the contacts for troubleshooting. --- ## 3. Wiring and Pin Layout The relay uses a standard pinout designed to fit into an **RXZE** series socket (e.g., RXZE2M114). | Pin Numbers | Function | | :--- | :--- | | **13 - 14** | Coil Terminals (A1 - A2) | | **9 - 12** | Common (C) | | **1 - 4** | Normally Closed (NC) | | **5 - 8** | Normally Open (NO) | --- ## 4. Applications Because of its compact size and high switching capacity, it is commonly used for: * **PLC Output Buffering:** Protecting PLC outputs from high-current loads. * **Isolation:** Separating control circuits from power circuits. * **Logic Interlocking:** Simple hard-wired logic in motor control centers.
