The **RXM2AB2P7PVM** is a specific part number belonging to the **Zelio Relay** family by Schneider Electric (formerly Telemecanique). It is a miniature plug-in relay designed for industrial automation control systems. --- ## 1. Technical Specifications The following table breaks down the primary electrical and physical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Relay Type** | Miniature Plug-in Relay | | **Contact Composition** | 2 C/O (DPDT - Double Pole Double Throw) | | **Control Circuit Voltage** | 230 V AC | | **Thermal Current (Ith)** | 12 A at -40…55 °C | | **Status LED** | Yes (Built-in for visual diagnostics) | | **Control Type** | Lockable test button | | **Contact Material** | AgNi (Silver Nickel) | | **Switching Capacity** | 3000 VA / 336 W | --- ## 2. Component Breakdown ### A. The Control Circuit (Coil) The **230V AC coil** is the input side of the relay. When power is applied to the coil terminals (usually A1 and A2), an electromagnetic field is generated. This pulls the internal armature to switch the contact positions. ### B. The Contact System (2 C/O) This relay features two sets of Change-Over (C/O) contacts. Each set consists of: * **Common (C)** * **Normally Open (NO)** * **Normally Closed (NC)** Having two poles allows you to control two independent circuits simultaneously or create complex logic interlocking. ### C. Maintenance Features * **Mechanical Indicator:** A small orange flag that moves when the relay is energized. * **Lockable Test Button:** Allows technicians to manually force the contacts to change state for troubleshooting without needing to energize the coil. * **LED Pilot Light:** Illuminates when the coil is receiving the 230V AC signal. --- ## 3. Terminal Mapping (Common Layout) | Terminal Pin | Function | | :--- | :--- | | **13 - 14 (A1-A2)** | Coil Input (230V AC) | | **9 - 12** | Common Terminals (Pole 1 & 2) | | **5 - 8** | Normally Open (NO) Contacts | | **1 - 4** | Normally Closed (NC) Contacts | --- ## 4. Usage Environment This relay is typically mounted on a **DIN Rail socket** (such as the RXZE series). It is widely used in: * Motor control centers (MCC). * PLC output isolation (protecting PLC outputs from high-current loads). * Lighting control systems. * HVAC sequencing.
