The **M2VF2-44W-R2/CE** is a high-performance, industrial-grade **Universal Analog Signal Converter (Signal Conditioner)** manufactured by **M-System**. It is part of the M2-series and is designed to interface between field sensors and control systems (like PLC/DCS). --- ### 1. Key Technical Specifications The part number breaks down into specific electronic characteristics: | Specification | Details | | :--- | :--- | | **Model Series** | M2VF2 (Ultra-slim Signal Conditioner) | | **Input Type** | **Universal Input**: DC Voltage or Current (Configurable) | | **Output Type** | **Dual Output**: Typically 0–10V DC / 4–20mA DC (Programmable) | | **Power Supply (44)** | 100 – 240V AC (Wide range AC) | | **Output Code (W)** | Dual Independent Outputs | | **Mounting (R2)** | DIN Rail Mounting (Type R2 housing) | | **Certification (CE)** | CE Marking (European Safety Standards) | --- ### 2. Functional Electronic Components #### A. Isolation Barrier The device provides **three-way isolation** (Input to Output to Power). This is electronically achieved using: * **Optocouplers/Transformers:** To prevent ground loops and protect sensitive PLC inputs from high-voltage surges in the field. * **Dielectric Strength:** Usually rated for 2000V AC @ 1 minute. #### B. Signal Processing (A/D & D/A) * **Microprocessor Controlled:** Unlike old analog potentiometers, this unit uses a digital processor to linearize signals and allow for software-based configuration. * **16-bit Resolution:** High-precision Analog-to-Digital conversion ensures minimal signal loss during the conditioning process. #### C. Power Management * **Switch-mode Power Supply (SMPS):** The "44" designation indicates an internal power circuit capable of handling global AC voltages (100-240V) with high efficiency and low heat dissipation. --- ### 3. Usage & Application This part is used in environments where electronic signals need to be "cleaned up" or "duplicated." 1. **Signal Conversion:** Converting a 0-10V sensor signal into a 4-20mA signal for long-distance transmission. 2. **Signal Splitting:** The "W" (Dual Output) feature allows one sensor input to be sent to two different devices simultaneously (e.g., a local display and a remote PLC) without signal degradation. 3. **Noise Reduction:** Electronic filtering circuits inside the M2VF2 remove electromagnetic interference (EMI) from the raw input signal. --- ### 4. Wiring Diagram Overview * **Terminals 1-2:** Power Input (AC). * **Terminals 5-6:** Input Signal (from Sensor). * **Terminals 7-8:** Output 1. * **Terminals 9-10:** Output 2.
