The **M2VT-A1-R** is a specific model of a **Signal Conditioner (Transmitter)** manufactured by **M-System**. It is designed to convert a DC voltage or current input signal into a standard DC output signal, providing electrical isolation between the input, output, and power supply. --- ### 1. Model Code Breakdown The model name follows a specific nomenclature that defines its electronic capabilities: | Code Segment | Description | Specific Value for M2VT-A1-R | | :--- | :--- | :--- | | **M2VT** | Series Name | M2-Unit Series Signal Conditioner | | **A** | Input Type | 4 – 20 mA DC | | **1** | Output Type | 0 – 10 V DC | | **R** | Power Supply | 24V DC | --- ### 2. Key Technical Specifications The internal circuitry is designed for high precision and industrial-grade reliability. * **Isolation:** 3-way isolation (Input to Output to Power). * **Construction:** Plug-in base socket for easy maintenance. * **Response Time:** $\leq$ 0.5 seconds (0 – 90%). * **Accuracy:** $\pm$0.1% of span. * **Temperature Coefficient:** $\pm$0.015% per degree Celsius. --- ### 3. Electronic Components & Terminal Layout The device consists of an internal PCB housed in a flame-resistant resin case. Below is the typical pin configuration for the electronic interface: | Terminal | Function | Description | | :--- | :--- | :--- | | **1** | Output (+) | 0 – 10V Positive lead | | **2** | Output (-) | 0 – 10V Negative lead | | **3** | Power (U) | +24V DC Supply | | **4** | Power (V) | 0V (Ground) Supply | | **5** | Input (+) | 4 – 20mA Positive source | | **6** | Input (-) | 4 – 20mA Return | --- ### 4. Application Use Case The M2VT-A1-R is primarily used in industrial automation to solve impedance matching or ground loop problems. **Example Scenario:** A sensor outputs a **4-20mA** current loop, but a PLC or Motor Drive only accepts a **0-10V** voltage signal. The M2VT-A1-R acts as the electronic bridge, converting the signal while protecting the PLC from electrical noise or surges originating at the sensor. --- ### 5.
