The **M2VT-AD-R/CE** is a high-performance, ultra-slim signal conditioner (transducer) manufactured by **M-System**. This specific model is designed to convert a DC input signal into two isolated DC output signals. Below is a detailed breakdown of its electronic specifications and technical characteristics. --- ### 1. Model Code Breakdown The model name follows a specific nomenclature that defines its electronic capabilities: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **M2VT** | Model Series | M2-Unit Series Mini-M Signal Conditioner | | **AD** | Input/Output Type | DC Input / DC Output (V-to-V or V-to-I) | | **R** | Power Input | 24V DC | | **CE** | Compliance | European Conformity (CE) Certified | --- ### 2. Electronic Specifications The internal circuitry is designed for precision and high galvanic isolation between the input, outputs, and power supply. #### Core Technical Data * **Input Impedance:** Usually $1\text{M}\Omega$ minimum for voltage inputs. * **Response Time:** $\leq 0.5$ seconds (0 – 90%). * **Accuracy:** $\pm 0.1\%$ of span. * **Temperature Coefficient:** $\pm 0.015\% / ^\circ\text{C}$. * **Isolation:** 4-way isolation (input to output 1 to output 2 to power). * **Dielectric Strength:** 2000V AC @ 1 minute. --- ### 3. Key Electronic Features #### A. Dual Isolated Outputs The "AD" configuration allows the device to take one sensor input and split it into two independent, isolated signals. This prevents ground loops if Output 1 goes to a PLC and Output 2 goes to a local display or chart recorder. #### B. Power Supply Design The **"R"** designation signifies a **24V DC** power requirement. * **Permissible Range:** 24V DC $\pm 10\%$. * **Current Consumption:** Approximately 50 mA. * **Protection:** Includes polarity protection and surge suppression. #### C. Front Panel Adjustments The unit contains two multi-turn potentiometers accessible via the front: 1. **Zero Adjustment:** Fine-tunes the lower end of the signal (e.g., setting 4mA or 0V). 2. **Span Adjustment:** Fine-tunes the upper end of the signal (e.g., setting 20mA or 10V). --- ### 4. Circuitry and Housing * **Construction:** Plug-in socket structure. The electronic module can be removed from the base without disconnecting the wires. * **Housing Material:** Flame-resistant resin (Black). * **Status Indicator:** A green LED on the front indicates the power status. ---
