The **M2UDS2-FW3-R2/N** is a specific part number typically associated with **M-System** (now MG CO., LTD.) signal conditioners or remote I/O modules. Specifically, it belongs to the **M2UDS2 series**, which are ultra-slim, signal splitters/conditioners. --- ## 1. Technical Specifications Breakdown The part number follows a specific nomenclature. Here is a breakdown of the electronic characteristics: | Code | Parameter | Description | | :--- | :--- | :--- | | **M2UDS2** | Model Series | Ultra-slim (5.9mm) Signal Splitter / Conditioner | | **F** | Input Type | 4 – 20 mA DC | | **W** | Output-1 / Output-2 | Dual Output: 4 – 20 mA DC / 4 – 20 mA DC | | **3** | Power Input | 24V DC | | **R2** | Option / Configuration | Specific manufacturer calibration or response speed | | **N** | Standards | Without CE marking (standard industrial spec) | --- ## 2. Key Electronic Features ### A. Dual Isolation & Splitting This device functions as a **Signal Splitter**. It takes one analog input (4-20mA) and produces two independent, isolated analog outputs. This is electronically critical for: * Preventing ground loops between a field instrument and two different receiving devices (e.g., a PLC and a local display). * Protecting the primary control loop if the secondary loop fails. ### B. Ultra-Slim Form Factor At only **5.9 mm (0.23 inches)** wide, the electronic components are densely packed using surface-mount technology (SMT) to allow high-density DIN rail mounting. ### C. Signal Accuracy and Response * **Accuracy:** Typically ±0.1% of span. * **Isolation:** 2000V AC isolation between Input, Output 1, Output 2, and Power. * **Response Time:** The "R2" variant usually denotes a specific response time (standard is often $\le$ 0.5 seconds to reach 90%). --- ## 3. Wiring Configuration The electronic terminals are typically organized as follows: | Terminal No. | Function | Description | | :--- | :--- | :--- | | **1 - 2** | Output 1 | 4 - 20 mA DC | | **3 - 4** | Output 2 | 4 - 20 mA DC | | **5 - 6** | Input | 4 - 20 mA DC (Current Loop) | | **7 - 8** | Power Supply | 24V DC (+ / -) | --- ## 4. Application Use-Case The **M2UDS2-FW3-R2/N** is electronically designed for industrial automation where space is at a premium. * **Example:** A flow meter sends a 4-20mA signal to the M2UDS2. The module splits this signal to send one to the **DCS (Distributed Control System)** for process control and the other to a **Paperless Recorder** for data logging.
