The **W2VS-2BY-R2** is a high-performance signal transducer (isolator) manufactured by **M-System**. It is part of the W2 series, characterized by its ultra-slim design and dual-channel (split) output capability. ### 1. Technical Specifications The model number breaks down into specific electronic characteristics: | Component | Description | | :--- | :--- | | **Model Series** | **W2VS**: Splitter/Isolator (converts one input to two isolated outputs) | | **Input** | **2**: 1 – 5V DC | | **Output 1** | **B**: 2 – 10V DC | | **Output 2** | **Y**: 0.2 – 1V DC (Custom/Special Range) | | **Power Input** | **R2**: 11 – 27V DC | --- ### 2. Key Electronic Features * **Dual Output (Signal Splitter):** The device takes a single analog input and provides two independent, galvanically isolated outputs. This allows one signal to be sent to a PLC and another to a local display or recorder simultaneously. * **Galvanic Isolation:** It provides 3-way isolation (Input to Output to Power). This protects sensitive control equipment from electrical noise, surge, and ground loops. * **Precision Circuitry:** * **Accuracy:** Typically ±0.1% of span. * **Response Time:** Approximately 0.5 seconds (0 to 90%). * **Temperature Coefficient:** ±0.015% per °C. * **Form Factor:** Designed for DIN rail mounting with a very slim profile (20mm width), optimizing cabinet space. --- ### 3. Wiring Configuration The unit typically uses screw terminals. Below is a simplified representation of the pin logic: | Terminal | Function | | :--- | :--- | | **Input (+ / -)** | Receives the 1-5V DC source signal. | | **Output 1 (+ / -)** | Sends the 2-10V DC signal. | | **Output 2 (+ / -)** | Sends the 0.2-1V DC signal. | | **Power (+ / -)** | Connects to 24V DC (R2 range). | --- ### 4. Typical Applications 1. **Ground Loop Elimination:** Preventing interference when the sensor and the controller are at different ground potentials. 2. **Signal Conversion:** Changing a voltage range (e.g., 1-5V) into a different range required by legacy hardware (e.g., 2-10V). 3. **Redundancy:** Sending the same process variable to two different monitoring systems.
