The **W2VS-2BY-R** is a specific model within the **W2VS series** of signal transducers/converters, typically manufactured by companies like **M-System**. These devices are used in industrial automation to convert a standard signal into two isolated outputs. ### Technical Overview The "W2VS" series is generally categorized as an **Ultra-slim Signal Splitter**. Its primary function is to take one analog input and provide two independent, galvanically isolated analog outputs. --- ### Part Number Breakdown While specific prefixes can vary by manufacturer, the common nomenclature for this series is as follows: | Code Segment | Description | Typical Specification | |:---|:---|:---| | **W2VS** | Series Name | Ultra-slim Signal Splitter (2-output) | | **2** | Output 1 | 4 – 20 mA DC | | **B** | Output 2 | 2 – 10 V DC (or specific voltage range) | | **Y** | Power Input | 200 – 240V AC (or 24V DC depending on sub-brand) | | **R** | Special Feature | Often denotes RoHS compliance or specific mounting | --- ### Key Electronic Specifications These devices are designed for precision and reliability in harsh industrial environments. * **Isolation:** 3-way or 4-way isolation (Input to Output 1 to Output 2 to Power). * **Response Time:** Typically $\leq$ 0.5 seconds (standard) or faster for high-speed models. * **Accuracy:** Generally within $\pm$0.1% of span. * **Construction:** Slim-line housing (often 12.5mm or 20mm width) for DIN rail mounting. * **Input Impedance:** * Current Input: Approx. 250 $\Omega$ * Voltage Input: $\geq$ 1 M$\Omega$ --- ### Typical Circuit Application In an industrial control loop, the W2VS-2BY-R acts as a "buffer" and "splitter." 1. **Input:** Receives a signal from a sensor (e.g., a flow meter or pressure transmitter). 2. **Internal Processing:** The signal is passed through an isolation transformer or optoisolator to prevent ground loops. 3. **Output 1:** Sends a 4-20mA signal to a PLC (Programmable Logic Controller). 4. **Output 2:** Sends a voltage signal (like 1-5V or 2-10V) to a local digital display or a chart recorder. ### Connection Diagram (General) ```text [ Power Supply ] --------> [ L / N ] [ Input Signal ] --------> [ + / - ] [ Output 1 ] <-------- [ + / - ] [ Output 2 ] <-------- [ + / - ] ``` --- ### Important Features * **Zero and Span Adjustment:** Most models feature front-facing potentiometers to fine-tune the output signals. * **Galvanic Isolation:** Protects sensitive control equipment from high-voltage surges on the field side. * **Space Saving:** The "W2" designation usually implies a slim profile, allowing more units to be packed into a control cabinet.
