The **M2VS-D1-R/N** is a high-performance **Signal Conditioner (Isolator)** manufactured by **M-System**. It is part of the Mini-M series, designed to convert a DC input signal into an isolated standard process signal. Below is a detailed breakdown of its electronic specifications and technical characteristics. ### 1. General Specifications | Feature | Specification | | :--- | :--- | | **Model Series** | Mini-M Series (Plug-in) | | **Function** | DC Voltage/Current Isolation and Conversion | | **Power Input (R)** | 24V DC | | **Accuracy** | ±0.1% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation** | 3-way (Input to Output to Power) | --- ### 2. Model Suffix Breakdown The suffix **D1-R/N** provides specific details about the electronic configuration: * **D**: Input Type (0 – 20 mA DC) * **1**: Output Type (0 – 10 mV DC) * **R**: Power Input (24V DC) * **N**: Option Code (No specific special option, standard type) --- ### 3. Electronic Components & Terminal Layout The device utilizes a plug-in base design for easy maintenance without disturbing the wiring. | Terminal No. | Assignment | Description | | :--- | :--- | :--- | | **1** | Output (+) | Positive Voltage Output | | **2** | Output (-) | Negative Voltage Output | | **3** | Power (U) | +24V DC Supply | | **4** | Power (V) | 0V DC Supply | | **5** | Input (+) | Positive Current Input | | **6** | Input (-) | Negative Current Input | --- ### 4. Key Electronic Features * **Galvanic Isolation:** It provides 2000V AC isolation between input, output, and power supply. This prevents ground loops and protects sensitive PLC/DCS equipment from electrical surges. * **Zero/Span Adjustment:** Front-mounted potentiometers allow for fine-tuning (±5% range) to calibrate the signal precisely. * **Current Protection:** The input circuit is designed to handle standard industrial loops with low input impedance (typically 50Ω for mA inputs). * **LED Indicator:** A power LED on the front panel indicates the operational status of the internal electronics. --- ### 5. Environmental Limits | Parameter | Limit | | :--- | :--- | | **Operating Temperature** | -5 to +55°C (23 to 131°F) | | **Operating Humidity** | 30 to 90% RH (non-condensing) | | **Mounting** | DIN rail or Surface mount |
