The **M2RTS-S-AB-R/Q** is a high-precision, programmable signal transducer (often referred to as a "Transmitter") manufactured by **M-System**. It is designed to convert DC input signals into standard industrial output signals while providing electrical isolation. --- ## 1. Core Technical Specifications | Feature | Description | | :--- | :--- | | **Model Series** | M2RTS (Super-mini Signal Conditioner) | | **Input Type** | Programmable DC Input (Volts/Amps) | | **Output Type** | Programmable DC Output (Volts/Amps) | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Mounting** | DIN rail or Surface mount | | **Configuration** | PC programmable or via on-device buttons | --- ## 2. Model Suffix Breakdown The specific suffixes in **M2RTS-S-AB-R/Q** define the electronic hardware configuration: * **S (Input Type):** High-speed response or specific sensitivity range (usually standard input selection). * **AB (Power Supply):** * **A:** 100 – 240V AC * **B:** 24V DC (Note: In some M-System series, 'AB' refers to a universal power range or specific terminal block type). * **R (Output Signal):** Typically indicates a specific output range or a Relay contact option depending on the exact sub-series. * **Q (Option):** Indicates a "Special Order" or specific coating (e.g., Conformal coating for moisture/corrosion protection). --- ## 3. Electronic Components & Functionality ### A. Signal Conditioning Circuitry The device uses a high-resolution **A/D Converter** to digitize the analog input. This allows for linearization and scaling via software before passing the signal through an **Optical Isolator**. ### B. Galvanic Isolation To prevent ground loops and protect sensitive PLC/DCS equipment, the M2RTS employs **3-way isolation**: 1. **Input Circuit:** Protected against surges. 2. **Output Circuit:** Isolated from the input and power source. 3. **Power Supply:** Isolated to prevent noise injection from the mains. ### C. Programmable Parameters Using the M-System "Configurator" software, the following can be adjusted: * **Zero/Span:** Calibration offsets. * **I/O Range:** Switching between 4-20mA, 0-10V, etc. * **Filter Time Constant:** To smooth out noisy input signals. --- ## 4.
