The **M2VF-00-R2/CE** is a high-performance **Signal Conditioner** (specifically a V-Network Transmitter) manufactured by **M-System**. It is designed to convert a DC voltage or current input signal into a standard process signal while providing galvanic isolation. --- ### ## Technical Specifications The following table outlines the primary electronic characteristics of the M2VF-00-R2/CE model: | Parameter | Specification | | :--- | :--- | | **Model Type** | M2-Unit Series Signal Conditioner | | **Input Signal** | 0 – 10V DC (Configurable) | | **Output Signal** | 4 – 20mA DC | | **Power Input** | 100 – 240V AC (R2 designation) | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Dielectric Strength** | 2000V AC @ 1 minute | | **Accuracy** | ±0.1% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Construction** | Plug-in base socket mount | --- ### ### Key Electronic Components & Design 1. **Isolation Barrier (3-Way Isolation):** The device utilizes internal optoisolators or magnetic transformers to separate the input, output, and power circuits. This prevents ground loops and protects sensitive PLC/DCS equipment from high-voltage surges. 2. **R2 Power Module:** The "R2" suffix indicates a wide-range AC power supply. Internally, it uses a switching regulator to handle fluctuations between 100V and 240V AC, ensuring a stable internal DC voltage for the signal processing components. 3. **Adjustment Potentiometers:** The front panel features multi-turn trimmers for **ZERO** and **SPAN** adjustments. These allow for fine-tuning the calibration to account for line resistance or specific sensor offsets. 4. **CE Compliance (CE Suffix):** The "CE" marking indicates that the internal electronics are shielded and filtered to comply with European Electromagnetic Compatibility (EMC) standards and Low Voltage Directives. --- ### ### Terminal Configuration The device uses a standard 8-pin or 11-pin base. Below is a typical wiring logic for this series: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1 & 2** | Output (+) / (-) | Connected to the receiving instrument (e.g., PLC) | | **4 & 5** | Input (+) / (-) | Connected to the source signal (e.g., Sensor) | | **7 & 8** | Power U (+) / V (-) | AC Power supply connection | --- ### ### Application Use Case This part is typically used in industrial automation where a high-voltage DC signal needs to be converted into a current loop (4-20mA) for long-distance transmission without noise interference.
