The **M2VT-163-R/K** is a specific model of a **Signal Conditioner** (Isolator/Converter) manufactured by **M-System**. It is designed to take a DC voltage or current input and convert it into two isolated DC outputs. Below is a breakdown of the electronic specifications and part characteristics. --- ### 1. Part Number Breakdown The suffix determines the power supply and specific input/output configurations: | Component | Code | Description | | :--- | :--- | :--- | | **Model** | M2VT | Dual Output Signal Conditioner (Slim Line) | | **Input** | 1 | 0 – 10 mV DC | | **Output 1** | 6 | 1 – 5 V DC | | **Output 2** | 3 | 0 – 1 V DC | | **Power Supply** | R or K | **R:** 24V DC / **K:** 85 – 132V AC | --- ### 2. Key Electronic Features * **Dual Isolation:** The unit provides isolation between input, output 1, output 2, and power. This prevents ground loops and protects sensitive PLC/DCS inputs from surges. * **Form Factor:** It is a "M2-unit" series, known for its plug-in base socket mounting, making it easy to replace without disconnecting wires. * **Calibration:** Equipped with Zero and Span adjustments on the front panel to fine-tune the signal accuracy. --- ### 3. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Accuracy** | ±0.1% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation Resistance** | 100 MΩ or more (500V DC) | | **Dielectric Strength** | 2000V AC @ 1 minute | | **Operating Temp** | -5 to +55 °C (23 to 131 °F) | | **Mounting** | DIN rail or Surface mount via socket | --- ### 4. Circuit Diagram Logic Internally, the device follows this electronic signal path: 1. **Input Stage:** Receives the low-voltage millivolt signal (0-10mV). 2. **Amplification & Isolation:** Uses an optical or transformer-based isolator to separate the circuit. 3. **Output Stage 1:** Scales the signal to a standard 1–5V DC range. 4. **Output Stage 2:** Scales the signal to a 0–1V DC range for secondary monitoring or logging. ---
