The **M2UDS-5W0-R2** is a specific model of an **Ultra-Slim Digital Meter (Transducer)** manufactured by **M-System**. It is designed to receive a DC voltage or current signal and convert it into a digital display and/or analog output. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Technical Specifications The "M2UDS" series is known for its space-saving design and high precision. | Parameter | Specification Details | | :--- | :--- | | **Model Type** | Ultra-Slim Digital Panel Meter / Transducer | | **Input Signal** | 4 – 20 mA DC (Standard for 5W0 code) | | **Output Type** | Dual Output (Relay/Analog options depending on configuration) | | **Power Input (R2)** | 11 – 27 V DC | | **Accuracy** | ±0.1% of span | | **Display** | 4-digit Red LED | | **Mounting** | DIN Rail Mounting (M2 series standard) | --- ### 2. Electronic Components & Features This device functions as a signal conditioner with the following internal electronic blocks: * **A/D Converter:** High-resolution Analog-to-Digital converter that processes the incoming DC signal for digital display. * **Isolation Circuitry:** Provides 2000V AC isolation between input, output, and power. This prevents ground loops and protects sensitive PLC/DCS equipment. * **Microprocessor Control:** Allows for scaling (e.g., converting 4-20mA to 0-100.0%) and programmable alarm setpoints. * **LED Driver:** Manages the 4-digit display to provide real-time monitoring of the process variable. --- ### 3. Model Number Breakdown Understanding the specific suffixes of the **M2UDS-5W0-R2**: 1. **M2UDS:** Series name (Ultra-Slim Signal Conditioner with Display). 2. **5:** Input code (typically 4 – 20 mA DC). 3. **W:** Output code (indicates specific signal types, often dual outputs or programmable). 4. **0:** Options (standard configuration, no special options). 5. **R2:** Power Supply code (24V DC nominal, range of 11 – 27V). --- ### 4. Wiring Diagram (Simplified) While always referring to the manufacturer's manual, the general pin layout for the M2 series is: ```markdown Terminal | Function ---------|---------- 1 - 2 | DC Input (+) / (-) 3 - 4 | Output 1 5 - 6 | Output 2 (if applicable) 7 - 8 | Power Supply (24V DC) ``` ---
