The **W2VS-2116-R2/N** is a specialized electronic component, typically identified as a **Signal Conditioner** or **Isolated Transmitter** manufactured by **M-System** (now part of MG CO., LTD). It is primarily used in industrial automation to convert and isolate analog signals. --- ## 1. Technical Specifications This device acts as a bridge between field sensors and control systems (like PLCs), ensuring signal integrity. | Feature | Specification Details | | :--- | :--- | | **Model Series** | W2VS (Dual Output Signal Conditioner) | | **Input Type** | DC Voltage or Current (Varies by specific sub-code) | | **Output 1 & 2** | Independent analog outputs (e.g., 4-20mA, 0-10V) | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Power Supply** | 100 – 240V AC (Standard for /N suffix) | | **Mounting** | DIN Rail Mounting | --- ## 2. Key Electronic Components & Functions The internal circuitry is designed for precision and protection in harsh electrical environments. ### A. Galvanic Isolation Circuitry * **Opto-isolators / Transformers:** These components physically separate the input, output, and power circuits. This prevents ground loops and protects sensitive PLC inputs from high-voltage surges on the field side. * **Dielectric Strength:** Usually rated for 2000V AC per minute. ### B. Signal Conditioning Stage * **Operational Amplifiers (Op-Amps):** High-precision amplifiers scale the incoming low-level signal to the desired output range. * **Filtering:** Low-pass filters are integrated to remove high-frequency noise and electromagnetic interference (EMI) from the signal path. ### C. Power Supply Module (/N Variant) * **Switching Power Supply:** The "/N" designation often refers to the power specification. It converts the 100-240V AC mains into stable DC voltages required for the internal semiconductor components. --- ## 3. Terminal Connection Map The device features a plug-in base for easy maintenance. | Terminal No. | Function | Description | | :--- | :--- | :--- | | **1 - 2** | Output 1 | Primary analog signal output | | **3 - 4** | Output 2 | Secondary analog signal output | | **5 - 6** | Input | Signal from sensor/source | | **7 - 8** | Power Supply | AC Line and Neutral | --- ## 4. Application Use Case In a typical industrial setup, the W2VS-2116-R2/N is used when one sensor signal needs to be sent to two different devices: 1. **Output 1:** Sent to a **Local Display** for operators. 2. **Output 2:** Sent to a **Remote PLC/SCADA** for data logging. 3. **Benefit:** If the display fails or shorts out, the isolation ensures the PLC signal remains unaffected. ---
