The **M2RS-C1-R2/N** is a specific model of an **Ultra-Slim Plug-in Signal Conditioner** (Isolator) manufactured by **M-System**. It is designed to receive a DC input signal and provide a standard isolated DC output. Below is a breakdown of its electronic specifications and characteristics. --- ### 1. Model Code Breakdown The model name describes its specific hardware configuration: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **M2RS** | Series Name | Ultra-slim plug-in signal conditioner. | | **C1** | Input Signal | 1 to 5V DC. | | **R2** | Output Signal | 4 to 20mA DC. | | **N** | Power Input | 24V DC. | --- ### 2. Key Electronic Specifications The internal circuitry is designed for precision signal processing and galvanic isolation. | Parameter | Specification | | :--- | :--- | | **Input Resistance** | 1 MΩ minimum (voltage input). | | **Output Load Resistance** | 550 Ω maximum. | | **Accuracy** | ±0.1% of span. | | **Temp. Coefficient** | ±0.015%/°C (±0.008%/°F). | | **Response Time** | ≤ 0.5 seconds (0 – 90%). | | **Isolation** | 3-way isolation (input to output to power). | | **Dielectric Strength** | 2000V AC @ 1 minute. | --- ### 3. Electronic Design Features #### A. 3-Way Isolation The device utilizes optical or magnetic coupling to separate the **Input**, **Output**, and **Power** circuits. This prevents ground loops, reduces noise interference, and protects sensitive PLC/DCS equipment from high-voltage surges on the field side. #### B. Power Requirements The "/N" variant operates on **24V DC** (allowable range 24V ±10%). It features low power consumption, typically around **0.8W**, which reduces heat buildup in high-density control panels. #### C. Signal Conversion Logic The internal electronics perform a linear conversion. Since the input is 1-5V and the output is 4-20mA, the transfer function is: `Output (mA) = (Input (V) - 1) * 4 + 4` --- ### 4. Physical & Mounting Parts * **Construction:** Slim-line plug-in structure. * **Connection:** M3 screw terminals (nickel-plated steel). * **Housing Material:** Flame-resistant resin (Black). * **LED Indicator:** Typically includes a power LED to indicate the internal electronic status. ---
