The **W2VS-162A-R2/Q** is a high-precision, industrial-grade **Signal Conditioner (Isolator)** manufactured by **M-System**. It is specifically designed to take a DC input signal and provide two independent, isolated DC output signals. --- ### 1. Technical Specifications Below are the primary electronic characteristics of the device: | Feature | Specification | | :--- | :--- | | **Power Input** | 24V DC (Standard for R2 series) | | **Input Signal** | 4 – 20 mA DC (Current) | | **Output 1** | 4 – 20 mA DC | | **Output 2** | 1 – 5 V DC | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Response Time** | ≤ 0.5 seconds (0 to 90%) | | **Accuracy** | ±0.1% of span | | **Mounting** | DIN Rail or Surface Mount | --- ### 2. Breakdown of the Model Code The alphanumeric string identifies specific electronic configurations: * **W2VS**: Series prefix for a dual-output signal conditioner with ultra-slim housing. * **1**: Denotes the Input type (typically Current/Voltage). * **6**: Denotes Output 1 (4 – 20 mA DC). * **2**: Denotes Output 2 (1 – 5 V DC). * **R2**: Specifies the power source (24V DC). * **Q**: Indicates a specific quality option or special coating (often used for moisture/fungus resistance or specific industrial certifications). --- ### 3. Key Electronic Functions 1. **Signal Splitting:** It takes a single 4-20mA loop (e.g., from a sensor) and splits it into two different signals. This allows you to send one signal to a PLC and the other to a local display or chart recorder without interference. 2. **Galvanic Isolation:** It uses optical or magnetic coupling to ensure there is no electrical path between the input, outputs, and power supply. This protects sensitive equipment from high-voltage surges and ground loops. 3. **Impedance Matching:** It ensures that the input loop maintains the correct resistance and that the output drives the load effectively without signal degradation. --- ### 4. Wiring Diagram Overview The unit typically features a plug-in base or terminal blocks: ```text [Input Terminals] ---> [Internal Isolation/Amplifier] ---> [Output 1] ---> [Output 2] [Power Terminals] --------------------------------------> [Internal PSU] ``` ---
