The **M2VF2-B5W-R2/X1** is a specific model of a **Signal Conditioner (Transducer)** manufactured by **M-System**. It is designed to convert an AC voltage input into two isolated DC output signals. --- ### 1. Technical Specifications Below are the primary electronic characteristics for this specific configuration: | Feature | Specification | | :--- | :--- | | **Model Series** | M2VF2 (AC Voltage Transmitter) | | **Input Type** | AC Voltage (e.g., 0–110V, 0–220V) | | **Output 1** | DC Voltage or Current (Standard 4–20mA or 1–5V) | | **Output 2** | DC Voltage or Current (Dual output capability) | | **Power Input** | 24V DC (Indicated by code "R2") | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Mounting** | DIN Rail Mounting | --- ### 2. Breakdown of the Model Code To understand the electronic parts, we must decode the suffix: * **M2VF2**: The base unit for an AC Voltage Transmitter (RMS sensing or Mean-value sensing). * **B**: **Input Code**. Usually represents a specific AC range (e.g., 0–110V AC). * **5W**: **Output Code**. Represents Dual Output (Output 1: 4–20mA / Output 2: 1–5V DC typically, though specific codes vary by data sheet). * **R2**: **Power Supply**. Indicates **24V DC** power requirement. * **X1**: **Special Option**. Usually indicates a specific custom calibration or a non-standard coating/sealing for the internal circuit board. --- ### 3. Internal Components and Functionality The device operates through several electronic stages: 1. **Input Transformer:** Steps down the high AC voltage to a safe, low-level signal. 2. **Rectifier/Filter Circuit:** Converts the AC signal into a proportional DC level. 3. **Isolation Barrier:** Uses optical or magnetic coupling to ensure that high voltage spikes on the input side do not damage the PLC/DCS connected to the output. 4. **Amplifier/Driver Stage:** Scales the signal to the industry-standard outputs (e.g., 4-20mA) and ensures it can drive the required impedance load. 5. **DC-DC Converter:** Regulates the 24V DC power input to provide stable internal voltages for the circuitry. --- ### 4. Applications * **Monitoring Mains Voltage:** Sending real-time voltage data to a PLC. * **Generator Control:** Tracking output voltage levels in power systems. * **Signal Splitting:** Providing one signal to a local display and another to a remote control room simultaneously.
