The **W2VS-15B2-R/N** belongs to the **W2VS series** manufactured by **Watanabe Electric Industry**. This specific device is an **Isolating Signal Conditioner** (often referred to as a transducer or signal isolator). Below is a detailed breakdown of its electronic specifications and functions. --- ### 1. Product Identification & Specifications The alphanumeric code represents specific configurations for input, output, and power requirements: | Component | Code | Description | | :--- | :--- | :--- | | **Series** | W2VS | Slim-type Isolator (Double Output) | | **Input** | 1 | 0 to 10 mV DC | | **Output 1** | 5 | 4 to 20 mA DC | | **Output 2** | B | 2 to 10 V DC | | **Power Supply** | 2 | 100 to 240 V AC | | **Option 1** | R | Response time approx. 25ms | | **Option 2** | N | Standard Operating Temperature | --- ### 2. Key Electronic Features #### A. Dual Output Functionality Unlike standard isolators, this model provides **two independent outputs** from a single input signal. This allows you to send the signal to a local display (e.g., 2-10V) while simultaneously sending it to a PLC or DCS (e.g., 4-20mA). #### B. Galvanic Isolation The device provides three-way isolation between: 1. **Input Circuit** 2. **Output Circuits (1 and 2)** 3. **Power Supply** *This prevents ground loops and protects sensitive control equipment from high-voltage surges or noise.* #### C. Signal Conversion Logic The internal circuitry uses high-precision operational amplifiers and optoisolators (or magnetic coupling) to convert a low-level millivolt signal (0-10mV) into industry-standard current and voltage loops. --- ### 3.
