The **RXM2AB1BD** is a specific model of an electromechanical plug-in relay from the **Zelio Relay RXM** range, manufactured by Schneider Electric. It is widely used in industrial control systems for switching electrical loads. --- ### 1. Key Technical Specifications The part number "RXM2AB1BD" encodes its specific characteristics: | Feature | Specification | | :--- | :--- | | **Series** | Zelio Relay RXM | | **Contact Composition** | 2 C/O (Changeover / DPDT) | | **Control Circuit Voltage** | 24 V DC | | **Rated Current (Ie)** | 12 A | | **Status LED** | Included (Indicates if the coil is energized) | | **Control Type** | Lockable test button | --- ### 2. Physical and Internal Components The device consists of several critical electronic and mechanical parts: * **The Coil:** An electromagnetic copper winding that creates a magnetic field when 24V DC is applied. * **The Contacts:** Silver Alloy (AgNi) contacts that open or close the circuit. The "2 C/O" means it can control two separate circuits simultaneously. * **The LED Indicator:** A small light-emitting diode integrated into the housing to provide visual feedback on the power status of the coil. * **Mechanical Flag:** A mechanical indicator that shows the position of the contacts (even if power is off). * **Test Button:** A manual override (usually green for DC models) that allows technicians to test the circuit without energizing the coil. --- ### 3. Connection and Mounting This relay is typically used with a **plug-in socket** rather than being soldered directly. ```markdown Typical Compatible Sockets: - RXZE2M114 (Screw connector) - RXZE2S108M (Bus jumper compatible) ``` --- ### 4. Electrical Performance Data | Parameter | Value | | :--- | :--- | | **Rated Insulation Voltage** | 250 V (IEC) | | **Mechanical Durability** | 10,000,000 cycles | | **Electrical Durability** | 100,000 cycles (resistive load) | | **Operating Time** | 20 ms (between coil de-energization and NC contact closing) | | **Average Coil Consumption** | 0.9 W | ---
