The **M2RTS-R-CD-R/Q** appears to be a specific configuration of a signal transducer, likely part of the **M2 Series** by **M-System** (now MG CO., LTD). These devices are commonly used in industrial automation to convert temperature signals (like RTDs) into standard analog signals. Below is a breakdown of the electronic specifications and the nomenclature for this specific model. --- ### 1. Model Code Breakdown The alphanumeric string defines the specific hardware components and input/output characteristics: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **M2RTS** | Model Series | RTD Transmitter (Resistor Temperature Detector) | | **-R** | Power Input | 24V DC Power Supply | | **-C** | Input Signal | Cu 10 (Copper 10Ω) RTD input | | **-D** | Output Signal | 0 – 20 mA DC (Current output) | | **-R** | Standard Code | Standard configuration/Mounting | | **-Q** | Special Option | Quality control or specific customization (often involves specific certifications) | --- ### 2. Key Electronic Specifications The internal electronics are designed for high precision and electrical isolation to prevent ground loops in industrial environments. * **Input Section:** Designed to interface with a Copper 10Ω RTD. It utilizes a 3-wire lead wire compensation circuit to eliminate errors caused by the resistance of the connection cables. * **Isolation Technology:** This unit features **3-way isolation**. This means the **Input**, **Output**, and **Power Supply** are all electronically isolated from one another (typically up to 2000V AC). * **Output Drive:** The "D" code signifies a current output. The electronics can typically drive a load resistance of up to 750Ω. * **Zero/Span Adjustment:** The front panel usually contains multi-turn potentiometers to fine-tune the minimum (Zero) and maximum (Span) electronic signals. --- ### 3. Component Characteristics | Feature | Specification | | :--- | :--- | | **Supply Voltage** | 24V DC (±10%), approx. 2W power consumption | | **Accuracy** | Generally ±0.1% to ±0.2% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Temperature Coefficient** | ±0.015% per °C | | **Construction** | Plug-in base socket for DIN rail mounting | --- ### 4. Wiring Diagram (Simplified) The electronic terminals are generally assigned as follows: ```text [ Power Supply ] [ Input (RTD) ] [ Output ] + (Terminal 7) A (Terminal 1) + (Terminal 4) - (Terminal 8) B (Terminal 2) - (Terminal 5) B (Terminal 3) ``` ---
