The **M2VF-A5W-R/N** is a specific model of an **Ultra-Slim Signal Conditioner** (Transducer) manufactured by **M-System** (now MG CO., LTD). These devices are used in industrial automation to convert analog signals into different standardized electrical signals while providing galvanic isolation. --- ### 1. Part Number Breakdown The alphanumeric code identifies the specific electrical characteristics of the unit: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **M2VF** | Series Name | M2-Series Ultra-slim Signal Conditioner | | **A** | Input Signal | **4 – 20 mA DC** | | **5W** | Output Signal | **Dual Output** (Output 1: 0–5V DC / Output 2: 0–5V DC) | | **R** | Power Input | **24V DC** | | **N** | Standards/Options | No special CE/UL marking (standard version) | --- ### 2. Key Technical Specifications Below are the electronic parameters governing this component: #### **Input Specifications** - **Input Type:** Current (Active or Passive loop). - **Input Resistance:** Approx. 250 $\Omega$. - **Range:** 4 to 20 mA DC. #### **Output Specifications** - **Dual Output:** This model splits the input signal into two identical or independent 0–5V DC outputs. - **Load Resistance:** Output 1 & 2 must be $\ge$ 5000 $\Omega$. - **Response Time:** $\le$ 0.5 seconds (0 – 90%). #### **Power & Isolation** - **Supply Voltage:** 24V DC ($\pm$10%). - **Current Consumption:** Approx. 50 mA. - **Isolation Structure:** 3-way isolation (Input to Output to Power). - **Dielectric Strength:** 2000V AC @ 1 minute. --- ### 3. Electronic Architecture The internal circuitry typically consists of three main stages: 1. **Input Conditioning:** A precision shunt resistor converts the 4-20mA current into a voltage. An operational amplifier (Op-Amp) buffers this signal. 2. **Galvanic Isolation:** The signal is modulated (often via pulse-width modulation or optical coupling) to pass across an isolation barrier. This protects sensitive PLC/DCS inputs from high-voltage surges or ground loops. 3. **Output Stage:** A digital-to-analog converter or filtering stage recreates the signal as a steady 0-5V DC voltage, split into two independent buffers for Output 1 and Output 2. --- ### 4. Physical Form Factor * **Mounting:** DIN Rail (35mm). * **Connection:** M3 screw terminals. * **Housing Material:** Flame-resistant resin (black). * **Adjustments:** Zero and Span adjustments are located on the front panel for field calibration.
