The **M2VF-5W5W-R** is a high-performance **Signal Conditioner / Isolated Signal Converter** manufactured by M-System (a leader in industrial automation and interface technology). Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Device Overview The M2VF series is designed to convert a standard DC input signal into two isolated DC output signals. The "5W5W" designation specifically refers to the input/output range configurations. ### Key Specifications | Feature | Specification | |:---|:---| | **Model Type** | Ultra-Slim Signal Conditioner (M2 Series) | | **Input Signal** | 0 – 5V DC | | **Output 1** | 0 – 5V DC | | **Output 2** | 0 – 5V DC | | **Power Input (R)** | 24V DC | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Construction** | Plug-in style / DIN rail mount | --- ## 2. Electronic Components & Internal Functions The internal circuitry of the M2VF-5W5W-R is engineered for precision and industrial protection. ### A. Isolation Circuitry The device uses **Optical or Magnetic Isolation** to separate the input, output, and power supply. * **Dielectric Strength:** Usually rated at 2000V AC for 1 minute. * **Purpose:** Eliminates ground loops, reduces noise, and protects sensitive PLC/DCS controllers from high-voltage surges in the field. ### B. Signal Conversion & Linearization The core of the unit contains an operational amplifier (Op-Amp) network or a high-resolution A/D and D/A converter system. * **Accuracy:** Typically ±0.1% of span. * **Temperature Coefficient:** Ensures minimal drift ($\pm 0.015\% / ^\circ C$) during operation in varying cabinet temperatures. ### C. Power Supply Regulation The "R" suffix indicates a **24V DC** power requirement. * Internal voltage regulators ensure that fluctuations in the 24V source do not affect the stability of the 0-5V output signals. * The power consumption is remarkably low, typically around **0.8W**. --- ## 3. Terminal Connection Map The device features a plug-in base for easy maintenance without disconnecting wires. | Terminal No. | Function | Description | |:---:|:---|:---| | **1 / 2** | Output 1 (+) / (-) | 0–5V DC Signal to Controller A | | **3 / 4** | Output 2 (+) / (-) | 0–5V DC Signal to Controller B | | **5 / 6** | Input (+) / (-) | 0–5V DC Signal from Sensor | | **7 / 8** | Power (+) / (-) | 24V DC Operational Power | --- ## 4. Performance Features * **Response Time:** $\leq$ 3 milliseconds (0 – 90%). * **Load Resistance:** Output 1 and 2 require a load of $\geq$ 5000 $\Omega$ to maintain accuracy for a 5V signal. * **Zero/Span Adjustment:** Front-accessible multi-turn potentiometers allow for $\pm 5\%$ calibration adjustments. ---
