The **M2XR2-4V2-R/CE** is a high-performance, plug-in type signal conditioner (transmitter) manufactured by **M-System**. It is specifically designed to accept a DC input signal and provide two independent, isolated DC output signals. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Model Code Breakdown Understanding the specific suffix of the model reveals its configuration: | Component | Code | Specification | | :--- | :--- | :--- | | **Model** | **M2XR2** | Dual-output signal conditioner (Plug-in) | | **Input** | **4** | 0 – 10V DC | | **Output 1** | **V** | High-speed response | | **Output 2** | **2** | 1 – 5V DC | | **Power Input** | **R** | 24V DC | | **Standards** | **CE** | CE marking compliant | --- ### 2. Key Electronic Specifications The internal electronics are designed for industrial precision and signal integrity. * **Input Impedance:** Typically $\ge 1$ M$\Omega$ for voltage inputs to minimize loading effects on the source. * **Response Time:** The "V" version indicates a **High-speed response**, usually $\le 500$ μs (0 – 90%). Standard versions are typically around 0.5 seconds. * **Isolation Structure:** 4-way isolation. The Input, Output 1, Output 2, and Power are all galvanically isolated from one another. * **Isolation Resistance:** $\ge 100$ M$\Omega$ with 500V DC. * **Dielectric Strength:** 2000V AC @ 1 minute (Input to Output to Power to Ground). --- ### 3. Performance Characteristics This device is often used in critical control loops where signal splitting is required without interference. | Feature | Specification | | :--- | :--- | | **Accuracy** | $\pm 0.1\%$ of span | | **Temperature Coefficient** | $\pm 0.015\%$ per $^\circ C$ | | **Power Consumption** | Approx. 3W | | **Operational Temp** | -5 to +55 $^\circ C$ | | **Mounting** | Surface or DIN rail (uses a socket base) | --- ### 4. Circuit Diagram Representation Internally, the signal flows through several stages to ensure linearity and protection: ```mermaid graph LR Input[0-10V DC Input] --> ISO1[Isolation Barrier] ISO1 --> Amp[Signal Processing] Amp --> Out1[Output 1: High Speed] Amp --> Out2[Output 2: 1-5V DC] Power[24V DC] --> Reg[Voltage Regulator] Reg --> ISO1 ``` --- ### 5. Application Context Because this model features **High-speed response (V)**, it is specifically utilized in: * **Motion Control:** Synchronizing two different drives that require immediate signal updates. * **Data Acquisition:** Sending a signal to a PLC and a high-speed recorder simultaneously. * **Safety Interlocks:** Where a delay in signal transmission could result in equipment damage.
