The **W2VS-1BY-R** is a specific electronic component primarily identified as a **Signal Conditioner / Isolator** (specifically a Distributor/Transmitter) manufactured by companies like **M-System**. It is used in industrial automation to convert and isolate analog signals. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Signal Conditioner / Isolator | | **Input Signal** | 4 – 20 mA DC (2-wire transmitter) | | **Output 1** | 1 – 5 V DC | | **Output 2** | 4 – 20 mA DC | | **Power Input** | 100 – 240V AC (Standard R-Type) | | **Mounting** | DIN Rail or Surface Mount | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | --- ### 2. Functional Breakdown #### A. Power Supply (Input) The "R" suffix typically denotes the power supply rating. For the W2VS series, "R" usually indicates an **AC Power Supply (100–240V AC)**, making it versatile for global industrial grids without needing a separate DC transformer. #### B. Isolation (Galvanic Separation) This part provides **three-way isolation**: 1. **Input to Output:** Protects the controller (PLC/DCS) from surges at the sensor. 2. **Output to Output:** Prevents ground loops between different monitoring devices. 3. **Power to Signal:** Filters out electrical noise from the power line. #### C. Signal Conversion (Distributor) The device acts as a **Distributor**. It provides power (usually 24V DC) to a 2-wire field transmitter (like a pressure or temperature sensor) and simultaneously converts that current signal into two separate, isolated outputs for a PLC and a local display. --- ### 3. Terminal Configuration Example While you should always consult the specific datasheet, the W2VS series generally follows this logic: ```markdown - Terminals 1 & 2: Power Supply Input (AC) - Terminals 4 & 5: Input Signal (from Transmitter) - Terminals 6 & 7: Output 1 (e.g., 1-5V DC) - Terminals 8 & 9: Output 2 (e.g., 4-20mA DC) ``` --- ### 4. Applications * **Ground Loop Elimination:** Used when the sensor and the PLC are grounded at different potentials. * **Signal Splitting:** When one sensor needs to send data to two different systems (e.g., a Safety Instrumented System and a standard Data Logger). * **Long-Distance Transmission:** Converting weak signals to robust 4-20mA loops for long cable runs.
