The **M2VF-00-R2/Q** is a high-precision, plug-in type signal conditioner (specifically a **Voltage/Current Transmitter**) manufactured by **M-System**. It is designed to convert a DC input signal into a standard process signal (voltage or current) while providing electrical isolation. Below is a detailed breakdown of its electronic specifications and features. --- ### 1. Key Technical Specifications | Feature | Specification Details | | :--- | :--- | | **Model Series** | M2 (Mini-M) Series | | **Input Signal** | DC Voltage or Current (Configurable) | | **Output Signal** | DC Voltage or Current (Configurable) | | **Power Input (R2)** | 100 – 240V AC (50/60 Hz) | | **Accuracy** | ±0.1% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Dielectric Strength** | 2000V AC @ 1 minute | --- ### 2. Electronic Component Characteristics #### A. Power Supply (Code: R2) The "R2" suffix indicates a universal AC power supply module. - **Operational Range:** 85 to 264V AC. - **Consumption:** Approximately 3VA. - This section includes an internal switching regulator to stabilize the internal DC voltage regardless of fluctuations in the mains power. #### B. Isolation Circuitry One of the most critical electronic aspects of this part is the **3-way isolation**: - **Input side:** Protects the sensitive controller from field surges. - **Output side:** Prevents ground loops between the transmitter and the PLC/DCS. - **Power side:** Protects the device from mains noise. #### C. Calibration Adjustments The unit features front-facing potentiometers (trimmers) for fine-tuning: - **Zero Adjustment:** -5 to +5% range. - **Span Adjustment:** 95 to 105% range. --- ### 3. Application Circuit Example To integrate the M2VF into a control system, follow the standard terminal wiring logic: ```markdown Terminal Connection Map: 1. Input (+) 2. Input (-) 3. Output (+) 4. Output (-) 5. Power (L / +) 6. Power (N / -) ``` --- ### 4. Special Codes (/Q) The **/Q** suffix denotes that the part has **Special Specifications**. These are usually requested at the time of order and can include: - **/C:** Conformal coating (protection against humidity/corrosion). - **/SET:** Custom calibration range specified by the user. - **Exotic requirements:** Enhanced vibration resistance or specific testing certifications. ---
