The **M2XR2-1V2-R/UL** is a high-performance, plug-in type signal conditioner (specifically a DC Transmitter) manufactured by **M-System**. It is designed to take a DC input signal and convert it into a standard, isolated DC output. --- ### 1. General Specifications The device belongs to the **M2 series**, known for its compact design and reliability in industrial automation. | Feature | Specification | | :--- | :--- | | **Model** | M2XR2-1V2-R/UL | | **Input Signal** | 0 – 10V DC (Represented by code '1') | | **Output Signal** | 1 – 5V DC (Represented by code 'V2') | | **Power Input** | 24V DC (Represented by code 'R') | | **Certifications** | UL/cUL Listed | | **Construction** | Plug-in type with socket base | --- ### 2. Core Electronic Components & Architecture The device utilizes a specific electronic topology to ensure precision and signal integrity: * **Isolation Circuitry:** It features **three-way isolation** (Input to Output to Power). This prevents ground loops and protects sensitive control equipment from electrical surges or noise. * **Operational Amplifiers (Op-Amps):** High-precision amplifiers are used to scale and linearize the input signal. * **Power Supply Module:** A DC-to-DC converter is integrated to manage the 24V DC input and distribute stable voltage to the internal sensing components. * **Adjustment Trimmers:** The front panel contains **ZERO** and **SPAN** adjustments (potentiometers) to fine-tune the output accuracy (typically ±10% range). --- ### 3. Technical Parameters | Parameter | Value | | :--- | :--- | | **Accuracy** | ±0.1% | | **Response Time** | ≤ 0.5 seconds (0 to 90%) | | **Insulation Resistance** | 100 MΩ or more with 500V DC | | **Dielectric Strength** | 2000V AC @ 1 minute | | **Operating Temperature** | -5 to +55°C (23 to 131°F) | --- ### 4. Wiring and Installation The unit uses a **base socket** for easy maintenance, allowing the electronics to be replaced without disconnecting wires. ```text Terminal Connections (Typical): 1.
