The **M2UDS2-AD-R/CE** is a high-precision, ultra-slim signal conditioner (isolator) manufactured by **M-System**. It is designed to take a DC input signal and provide an isolated DC output, typically used in industrial automation to prevent ground loops and protect control systems. --- ## 1. Technical Specifications The following table outlines the primary electronic characteristics of this specific model: | Parameter | Specification | | :--- | :--- | | **Model Series** | M2UDS2 (Ultra-slim Signal Conditioner) | | **Input Signal** | Configurable (Current or Voltage) | | **Output Signal** | Configurable (Current or Voltage) | | **Power Input (AD)** | 100 – 240V AC / 24 – 240V DC (Universal) | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation** | 3-way (Input to Output to Power) | | **Dielectric Strength** | 2000V AC @ 1 minute | | **Mounting** | DIN Rail | --- ## 2. Component Breakdown (Suffix Meanings) The alphanumeric code provides specific details about the internal hardware configuration: * **M2UDS2**: The base series model (Dual Output/Universal Input/Slim type). * **-AD**: Indicates a **Universal Power Supply**. It can accept both high-voltage AC and a wide range of DC voltages. * **-R**: Indicates the **Relay** or specific **Output Type** (refer to data sheet for specific load impedance matching). * **CE**: Denotes compliance with European Safety and Electromagnetic Compatibility standards. --- ## 3. Key Electronic Features ### 3-Way Isolation The device electronically decouples the **Input**, **Output**, and **Power** circuits. This is critical for: * Eliminating ground loops in long-distance signal transmission. * Protecting PLCs/DCS units from high-voltage surges on the field side. ### Accuracy & Stability * **Accuracy:** Typically ±0.1% of span. * **Temperature Coefficient:** Ensures the signal remains stable even if the control cabinet heats up (typically ±0.015%/°C). ### Connection Diagram (Typical) ```text [Field Sensor] ----> (Input Terminals) [ M2UDS2 ] (Output Terminals) ----> [PLC/Controller] | [Power Supply] (100-240V AC/DC) ``` ---
