The **M2VF-60-R2/N** is a specific model of an **M2 Series Signal Conditioner** (specifically a V-Unit) manufactured by **M-System**. It is used in industrial automation to convert, isolate, and scale analog signals. --- ## 1. Technical Specifications Overview The model code `M2VF-60-R2/N` can be broken down into its specific electronic configurations: | Component Code | Description | Details | | :--- | :--- | :--- | | **M2VF** | Model Series | Ultra-slim Signal Conditioner (V-Unit) | | **60** | Input Type | 0 – 10V DC | | **R** | Output Type | 4 – 20mA DC | | **2** | Power Supply | 24V DC | | **N** | Option | No special options (Standard) | --- ## 2. Key Electronic Components & Functions ### A. Signal Conversion (V/I Conversion) The primary electronic function of this device is to take a **Voltage (0-10V)** input and convert it into a **Current (4-20mA)** output. This is essential for long-distance signal transmission, as current signals are less susceptible to voltage drops and electromagnetic interference (EMI). ### B. Galvanic Isolation (3-Way) The M2VF provides 3-way isolation between the **Input**, **Output**, and **Power Supply**. * **Isolation Resistance:** 100 MΩ or more with 500V DC. * **Dielectric Strength:** 2000V AC @ 1 minute (Input to output to power to ground). * **Electronic Benefit:** This prevents ground loops and protects sensitive PLC/DCS inputs from high-voltage surges on the field side. ### C. Zero and Span Adjustments On the front panel, there are multi-turn potentiometers for: * **Zero Adjustment:** Fine-tunes the 4mA floor. * **Span Adjustment:** Fine-tunes the 20mA ceiling. * **Range:** Usually ±5% of the scale. --- ## 3. Circuit Interface Details ### Wiring Terminal Assignments The unit typically uses a M3.5 screw terminal base. | Terminal No. | Function | Connection Type | | :--- | :--- | :--- | | 1 | Output (+) | 4-20mA | | 2 | Output (-) | 4-20mA | | 3 | Power (+) | 24V DC | | 4 | Power (-) | 24V DC | | 5 | Input (+) | 0-10V DC | | 6 | Input (-) | 0-10V DC | --- ## 4. Performance Characteristics * **Accuracy:** ±0.1% of span. * **Response Time:** ≤ 0.5 seconds (0 – 90%). * **Load Resistance:** Up to 550 Ω for the 4-20mA output. * **Housing:** Flame-resistant resin (Black). ---
