The **M2RTS-R-B1-PS/CE** is a high-performance **Resistance Temperature Detector (RTD) Transmitter** belonging to the M2 Series by M-System. It is designed to convert signals from an RTD sensor into a standard industrial DC signal. --- ### ## Technical Specifications Breakdown | Feature | Specification Details | | :--- | :--- | | **Model Series** | M2RTS (Ultra-slim Signal Conditioner) | | **Input Type** | RTD (Pt 100, Pt 50, JPt 100, etc.) | | **Configuration** | B1 (Specific Input/Output Range Code) | | **Power Input (P)** | 100 – 240V AC | | **Safety Standard (CE)** | CE Marking compliant | | **Output Signal** | Typically 4–20mA DC or 1–5V DC (Depending on calibration) | | **Accuracy** | ±0.1% of span | --- ### ### Key Electronic Components & Functions 1. **Isolation Circuitry:** The device features **three-way isolation** (Input to Output to Power). This protects the control system (like a PLC) from electrical noise, surges, or ground loops that may occur at the sensor site. 2. **Linearization Circuit:** RTD sensors have a non-linear resistance-to-temperature relationship. The internal electronics linearize this signal to ensure the output is proportional to the actual temperature. 3. **Burnout Protection:** In the event of a wire break in the RTD sensor, the transmitter's electronics are programmed to drive the output signal to a specific limit (Upscale or Downscale) to alert the operator. 4. **A/D and D/A Converters:** The analog resistance value is converted into a digital signal for processing and then back into a precise analog voltage or current for transmission over long distances. --- ### ### Physical Design * **Form Factor:** Plug-in base construction, allowing for easy maintenance without disconnecting wires. * **Mounting:** Standard DIN rail mounting. * **Housing:** Flame-resistant resin (black). ---
