The **M2VF-4FW-R2/N** is a specific model of an **Ultra-Slim Signal Conditioner (Isolator)** manufactured by **M-System**. It is designed to convert a standard DC input signal into two isolated DC output signals while maintaining a very slim profile for space-saving on DIN rails. --- ### 1. Model Breakdown The model number specifies the electrical characteristics and configuration: | Code Segment | Description | Specific Value | | :--- | :--- | :--- | | **M2VF** | Model Series | Ultra-Slim Signal Conditioner | | **4** | Input Signal | 0 – 10V DC | | **FW** | Output Signal | Dual Output (Output 1 & 2: 4 – 20mA DC) | | **R2** | Power Input | 24V DC | | **N** | Options | None (Standard) | --- ### 2. Key Technical Specifications These parts are engineered for high-precision industrial automation environments. * **Input Impedance:** 1 M$\Omega$ minimum. * **Output Load Resistance:** * Output 1: Max 550 $\Omega$. * Output 2: Max 550 $\Omega$. * **Response Time:** $\leq$ 0.5 seconds (0 – 90%). * **Isolation:** 4-way isolation (Input to Output 1 to Output 2 to Power). * **Isolation Resistance:** 100 M$\Omega$ at 500V DC. * **Dielectric Strength:** 2000V AC @ 1 minute (Input to Output to Power). --- ### 3. Functional Block Diagram (Internal Parts) The electronic architecture generally consists of the following stages: 1. **Input Conditioning:** High-impedance buffer stage to prevent loading the source sensor or PLC. 2. **Modulator/Isolator:** Uses an internal transformer or optocoupler to provide galvanic isolation. This prevents ground loops and protects sensitive equipment from high-voltage surges. 3. **Dual Output Driver:** Independent circuits that convert the isolated signal into two 4-20mA current loops. 4. **Power Supply Unit (PSU):** An internal DC/DC converter that takes the 24V DC input and creates isolated voltages for the input and output stages. --- ### 4. Installation and Physical Features * **Housing:** Flame-resistant resin (Black). * **Mounting:** DIN Rail (Standard 35mm). * **Wiring:** M3 screw terminals (torque 0.8 N·m). * **LED Indicators:** Power LED (Green) turns on when the 24V DC power is supplied correctly. --- ### 5. Application Example You would use this part if you have a sensor providing a **0-10V** signal, but you need to send that information to two different devices (for example, a **Local Display** and a **Remote PLC**) using **4-20mA** signals to ensure long-distance transmission without interference.
