The **M2VF-5WZ-R2** is a high-performance **Signal Conditioner (Transducer)** from the M2 Series manufactured by **M-System**. Its primary electronic function is to take a variable frequency input (from sensors like flow meters or tachometers) and convert it into an isolated analog output. --- ### 1. Model Breakdown The model number specifies the internal electronic configuration: | Component | Code | Description | | :--- | :--- | :--- | | **Model** | **M2VF** | Frequency Transmitter (Plug-in type) | | **Input** | **5** | Dry contact or Open Collector | | **Output** | **W** | Dual Output (Selectable voltage/current) | | **Power Supply** | **R2** | 110V AC (Standard range 100 – 120V AC) | --- ### 2. Key Electronic Specifications The internal circuitry is designed for precision and electrical isolation between the input, output, and power source. * **Input Circuitry:** Designed to detect pulses. It supports dry contact, open collector, or voltage pulses. It typically includes a noise filter to prevent false triggering from electromagnetic interference (EMI). * **Conversion Method:** It uses a frequency-to-DC conversion algorithm. The device measures the time between pulses or pulse counts and translates that into a proportional linear analog signal. * **Isolation:** 2000V AC isolation. This protects sensitive PLC/DCS inputs from high-voltage surges or ground loops on the sensor side. * **Response Time:** Approximately 0.5 seconds (0 to 90%). --- ### 3. Connection Diagram (General) The unit uses a base socket (typically M2-series 8-pin or 11-pin) for wiring: ```mermaid graph LR A[Frequency Sensor] -->|Pulse Signal| B(M2VF-5WZ-R2) B -->|Isolated DC| C[PLC/Controller] D[110V AC Power] --> B ``` --- ### 4. Technical Features 1. **Dual Output (W):** This version provides two independent analog outputs. For example, Output 1 could be 4–20mA for a control loop, while Output 2 is 0–10V for a local display. 2. **Adjustability:** The front panel usually features **Zero** and **Span** adjustments (multi-turn potentiometers) to calibrate the electronic output to the specific frequency range of your sensor. 3. **Construction:** Housed in a flame-resistant black resin case, designed for DIN-rail mounting.
