The **M2VF-BFW-R** is a specific model within the **M2VF series** of signal conditioners manufactured by **M-System**. This device is a high-speed, ultra-slim signal transmitter (isolator) designed to convert a DC input signal into a standard DC output signal while providing electrical isolation. --- ### 1. Model Breakdown (M2VF-BFW-R) | Code Segment | Description | Specific Value | | :--- | :--- | :--- | | **M2VF** | Series Name | Ultra-slim Signal Conditioner | | **B** | Input Signal | 2 – 10 V DC | | **F** | Output Signal | 4 – 20 mA DC | | **W** | Output Configuration | Dual Output (Independent) | | **R** | Power Input | 24V DC | --- ### 2. Key Electronic Specifications The internal circuitry is designed for high-density mounting and high-speed response. Below are the technical parameters: * **Isolation Structure:** 3-way isolation (Input to Output to Power). * **Response Time:** Approximately $\leq 2$ ms (0 – 90%). * **Accuracy:** $\pm 0.1\%$ of span. * **Temperature Coefficient:** $\pm 0.015\% / ^\circ\text{C}$. * **Insulation Resistance:** $\geq 100\text{ M}\Omega$ with 500V DC. * **Dielectric Strength:** 2000V AC @ 1 minute (Input to Output to Power to Ground). --- ### 3. Connection Diagram (General Layout) The device utilizes a plug-in socket base for easy maintenance. ```text [Input Terminals] (4) + Input (2-10V) (5) - Input [Output Terminals] (1) + Output 1 (4-20mA) (2) - Output 1 (3) + Output 2 (4-20mA) (6) - Output 2 [Power Terminals] (7) + 24V DC (8) - 0V DC ``` --- ### 4. Features & Usage 1. **High-Speed Processing:** Unlike standard transmitters that take 100ms+, the M2VF series is optimized for applications requiring rapid feedback loops. 2. **Dual Output:** The "W" in the code signifies that the device can take one input voltage and provide two isolated 4-20mA current signals. 3. **Space Saving:** The housing is typically only 5.9mm or 12.5mm wide (depending on specific housing revision), allowing for high-density DIN rail mounting. 4. **Zero/Span Adjustment:** Front-facing potentiometers allow for fine-tuning the output signals without removing the wiring.
