The **M2RTS-S-AE-R2/Q** is a high-performance, programmable signal conditioner (transducer) manufactured by **M-System**. It is specifically designed to accept a DC input and provide two isolated DC outputs. --- ## 1. Technical Specifications The following table outlines the primary electronic characteristics of this specific model: | Parameter | Specification | | :--- | :--- | | **Input Signal** | 4 – 20 mA DC | | **Output 1** | 4 – 20 mA DC | | **Output 2** | 1 – 5 V DC | | **Power Supply** | 24V DC | | **Accuracy** | ±0.1% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation** | 3-way (Input to Output to Power) | | **Mounting** | DIN Rail | --- ## 2. Model Code Breakdown Understanding the suffix codes helps identify the exact electronic configuration: * **M2RTS**: The series identifier (Ultra-slim Signal Conditioner). * **S**: Indicates a Current Input (e.g., 4-20mA). * **AE**: Represents the Output combinations. * **A**: 4 – 20 mA DC. * **E**: 1 – 5 V DC. * **R2**: Power input requirement (24V DC). * **Q**: Optional suffix, typically indicating a specific quality standard, custom labeling, or a non-standard coating for harsh environments. --- ## 3. Electronic Architecture The device functions as an active isolator and signal splitter. Internally, the circuit consists of: ### Signal Conditioning Layer The input stage converts the 4-20mA current into a digital value via an A/D converter or a precise analog shunt. This ensures the input impedance remains low (typically 250Ω) to avoid loading the source loop. ### Isolation Barrier It utilizes **Galvanic Isolation** (often optical or magnetic) between the input, output, and power supply. This protects sensitive PLC/DCS cards from ground loops and high-voltage surges up to 2000V AC. ### Dual Output Stage The signal is split into two independent drivers: 1. **Current Loop Driver:** Capable of driving loads up to 750Ω. 2. **Voltage Source:** Provides a low-impedance 1-5V signal for monitoring devices. --- ## 4.
