The **W2SP-2D3-R2/Q** is a specific model within the **W2 Series** of signal conditioners manufactured by **M-System (now MG CO., LTD.)**. These devices are designed for industrial automation to provide signal isolation, conversion, and splitting. --- ### 1. General Specifications This part is a **Signal Splitter** that takes one input signal and provides two isolated, independent output signals. | Feature | Specification | | :--- | :--- | | **Series** | W2 Series (Mini-M) | | **Model Type** | Signal Splitter (Two-wire transmitter use) | | **Configuration** | Plug-in base structure | | **Isolation** | 4-way isolation (input to output 1 to output 2 to power) | | **Construction** | Compact, high-density mounting | --- ### 2. Part Number Breakdown (W2SP-2D3-R2/Q) The suffix codes determine the electronic characteristics of the unit: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **W2SP** | Model Name | Signal Splitter for 2-wire transmitters | | **2** | Input | 4 – 20 mA DC (Excitation supply provided) | | **D** | Output 1 | 0 – 20 mA DC | | **3** | Output 2 | 0 – 1 V DC | | **R2** | Power Input | 11 – 27 V DC | | **Q** | Special Options | Optional feature (requires specific data sheet reference) | --- ### 3. Electronic Functionality The W2SP serves three primary electronic roles: * **Signal Conversion:** It converts a single current loop input (often from a 2-wire pressure or temperature transmitter) into two different types of signals (e.g., one current loop for a PLC and one voltage signal for a local display). * **Galvanic Isolation:** It prevents "ground loops" by ensuring there is no electrical path between the input sensor, the power supply, and the two output devices. * **Power Supply (Excitation):** The unit provides a 24V DC excitation supply to power the 2-wire transmitter connected to its input terminals. --- ### 4. Technical Performance * **Accuracy:** Typically ±0.1% of span. * **Response Time:** Approximately 0.5 seconds (0 – 90%). * **Isolation Resistance:** 100 MΩ or more with 500 V DC. * **Dielectric Strength:** 2000 V AC @ 1 minute (input to output to power to ground). ---
