The **M2RTS-R-3B-R/CE** is a high-performance **RTD (Resistance Temperature Detector) Transmitter** from the M2 Series by **M-System (now MG CO., LTD.)**. This electronic component is designed to convert signals from an RTD sensor into a standard industrial DC signal, providing electrical isolation and signal conditioning. --- ### ## Technical Specifications The model code `M2RTS-R-3B-R/CE` breaks down into specific electronic parameters: | Component Code | Specification | Description | | :--- | :--- | :--- | | **M2RTS** | Model Series | RTD Transmitter (M2-Series) | | **-R** | Power Input | 24V DC (Allowable range 24V ±10%) | | **-3** | Input Type | Pt 100 (ITS-90) | | **-B** | Output Type | 2 – 10V DC (Load resistance 5000 $\Omega$ min.) | | **-R** | Configuration | Remote programming via PC | | **-CE** | Certification | CE marking (European conformity) | --- ### ### Core Electronic Features #### 1. Signal Conditioning and Isolation The device features **three-way isolation** between the Input, Output, and Power Supply. This is critical in industrial environments to: * Prevent ground loops. * Protect sensitive PLC/DCS equipment from high-voltage surges. * Reduce electromagnetic interference (EMI). #### 2. Linearization and Compensation * **Burnout Protection:** The transmitter includes a burnout feature (upscale or downscale) that alerts the control system if the RTD sensor wire breaks. * **Leadwire Compensation:** Designed for 3-wire RTD setups to compensate for the resistance of the wires leading to the sensor, ensuring temperature accuracy. #### 3. Technical Performance * **Accuracy:** Typically ±0.1% of span. * **Response Time:** $\leq$ 0.5 seconds (0 – 90%). * **Insulation Resistance:** 100 M$\Omega$ minimum at 500V DC. * **Dielectric Strength:** 2000V AC @ 1 minute (Input to Output to Power to Ground). --- ### ### Installation & Wiring The unit is a **plug-in type**, meaning the electronic module can be removed from its base without disconnecting the wiring. ```text Terminal Connections (Example): 1.
