The **M2VF-4WA-R2/CE** is a high-performance electronic signal conditioner (specifically a transducer or transmitter) manufactured by **M-System**. It is designed to convert an AC voltage input into a standardized DC output signal. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Product Identification | Component | Description | | :--- | :--- | | **Model Series** | M2VF (Plug-in Signal Conditioner) | | **Input Type** | AC Voltage (Sine wave) | | **Output Type** | DC Voltage or Current (Dual/Single output options) | | **Housing** | Plug-in base for easy maintenance | ### 2. Electronic Specifications This device uses analog-to-DC conversion circuitry to provide isolation and signal scaling. | Parameter | Specification | | :--- | :--- | | **Power Input (R2)** | 100 – 240V AC (Operating range 85 – 264V AC) | | **Input Range (4W)** | 0 – 110V AC (Standard utility/transformer voltage) | | **Output Range (A)** | 4 – 20 mA DC (Load resistance max. 750 $\Omega$) | | **Accuracy** | ±0.3% of span | | **Response Time** | $\leq$ 0.5 seconds (0 – 90%) | | **Insulation Resistance** | 100 M$\Omega$ at 500V DC | | **Isolation** | Input to output to power to ground (2000V AC @ 1 min) | --- ### 3. Key Electronic Features * **True RMS Conversion:** While standard models use mean value processing, specific variations of this series handle distorted waveforms by converting the RMS value of the AC input to a linear DC signal. * **Isolation Circuitry:** It features high-voltage isolation between the input (high-voltage AC) and the output (low-voltage DC). This protects PLCs or SCADA systems from surges or ground loops. * **Zero and Span Adjustment:** The front panel typically includes multi-turn potentiometers to calibrate the 0% and 100% signal points. * **CE Marking:** The "/CE" suffix indicates the unit complies with European safety and Electromagnetic Compatibility (EMC) standards. --- ### 4.
