The **M2VF-5WZ-R** is a specific model of a **Signal Conditioner / Isolator** (V-Unit) manufactured by **M-System** (now MG CO., LTD). It is primarily used in industrial automation to convert, isolate, and transmit analog signals. --- ### ## Technical Specifications Breakdown The model number `M2VF-5WZ-R` follows a specific nomenclature that defines its electronic characteristics: | Code Segment | Specification | Description | | :--- | :--- | :--- | | **M2VF** | **Series** | V-Unit series Signal Conditioner (Plug-in base). | | **5** | **Input Signal** | 0 – 5V DC (High impedance). | | **W** | **Output 1 & 2** | Dual output (provides two independent signals). | | **Z** | **Output Signal** | Special/Custom Range (usually 0 – 10V DC or specified). | | **R** | **Power Input** | 24V DC power supply requirement. | --- ### ### Key Electronic Components & Functions 1. **Isolation Barrier (3-Port Isolation):** * The device provides electrical isolation between the **Input**, **Output**, and **Power supply**. * This prevents ground loops and protects sensitive control systems (like PLCs) from high-voltage surges on the field side. 2. **Analog-to-Analog Conversion:** * It uses precision operational amplifiers and high-stability resistors to scale the input voltage (0-5V) to the desired output levels accurately. 3. **Potentiometers (Adjustments):** * The front panel typically features **Zero** and **Span** adjustments. These allow fine-tuning of the signal output to compensate for line loss or sensor drift. 4. **Filter Circuitry:** * Includes low-pass filters to eliminate electromagnetic interference (EMI) and high-frequency noise from the signal path. --- ### ### Technical Data Summary | Feature | Details | | :--- | :--- | | **Supply Voltage** | 24V DC (±10%) | | **Isolation Resistance** | ≥ 100 MΩ with 500V DC | | **Dielectric Strength** | 2000V AC @ 1 minute (Input to output to power to ground) | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Accuracy** | ±0.1% of span | --- ### ### Wiring Configuration Example The unit uses a plug-in socket base (usually 11-pin or 8-pin depending on the specific V-Unit revision). ```text [PIN] [FUNCTION] 1 Output 1 (+) 2 Output 1 (-) 3 Input (+) 4 Input (-) 5 Output 2 (+) 6 Output 2 (-) 7 Power (+) 8 Power (-) ``` ---
