The **RXM2AB2BDPVS** is a specific industrial relay assembly within the Schneider Electric Harmony Relay range (formerly Zelio Relay). This part number typically refers to a pre-assembled combination of a miniature plug-in relay and its corresponding socket. --- ## 1. Component Breakdown The assembly is composed of two primary electronic/mechanical parts: | Component | Description | | :--- | :--- | | **Relay (RXM2AB2BD)** | A miniature intermediate power relay with a DC control coil. | | **Socket (RXZE2S111M)** | A screw-terminal base that allows for DIN-rail mounting and wiring. | | **Protection Module** | Usually includes a protection diode to suppress inductive voltage spikes. | --- ## 2. Technical Specifications The electronic performance is defined by the following parameters: ### Control Side (Input/Coil) * **Coil Voltage:** 24V DC. * **Control Type:** Direct Current (DC). * **Feature:** Integrated "Green LED" to indicate when the coil is energized. ### Switching Side (Output/Contacts) * **Contact Configuration:** 2 C/O (Changeover) or DPDT (Double Pole Double Throw). * **Rated Current ($I_{th}$):** 12A. * **Maximum Switching Voltage:** 250V AC / 28V DC. * **Contact Material:** Silver Alloy (AgNi) for improved conductivity and wear resistance. --- ## 3. Key Electronic Features * **Mechanical Indicator:** A small mechanical flag allows operators to see the contact state even if power is lost. * **Manual Test Button:** A lockable "Push-to-test" button allows manual overriding of the relay to test downstream circuits without energizing the coil. * **Voltage Surge Suppression:** Since this is a DC model, it often includes a diode across the coil to prevent "Back EMF" from damaging the PLC or controller driving the relay. --- ## 4. Pinout & Wiring Logic The 2 C/O configuration means there are two independent circuits being switched simultaneously. | Terminal Number | Function | | :--- | :--- | | **A1 / A2** | Coil Power (24V DC) | | **11 / 21** | Common (COM) | | **12 / 22** | Normally Closed (NC) | | **14 / 24** | Normally Open (NO) | --- ## 5. Applications * **PLC Interfacing:** Using a low-power 24V signal to switch high-power 120V/230V loads. * **Isolation:** Protecting sensitive electronic controllers from electrical noise and voltage spikes. * **Logic Multiplication:** Using one signal to trigger two separate electrical actions.
