The **M5VS-C4W-R** is a precision signal conditioner (isolator) manufactured by **M-System** (now part of the MG CO., LTD). It belongs to the M5-UNIT series, which is characterized by its ultra-slim profile and high-density mounting capabilities. --- ### 1. Key Technical Specifications The model code `M5VS-C4W-R` breaks down into specific electronic configurations: | Component Code | Description | Details | | :--- | :--- | :--- | | **M5VS** | Series Name | Ultra-slim Signal Conditioner | | **C** | Input Signal | 4 to 20 mA DC | | **4W** | Output Signal | 4 to 20 mA DC (Dual Output) | | **R** | Power Input | 24V DC | --- ### 2. Electronic Architecture The device functions as a **Loop Isolator/Splitter**. It takes one analog current input and provides two independent, isolated analog current outputs. #### Core Electronic Functions: 1. **Isolation:** Provides galvanic isolation between input, output 1, output 2, and power. This prevents ground loops and protects sensitive PLC/DCS inputs from voltage surges. 2. **Signal Splitting:** The "W" in the code signifies a dual-output configuration. This allows one sensor signal to be sent to two different devices (e.g., a local display and a remote controller) simultaneously. 3. **Signal Conversion:** It maintains a 1:1 ratio for the current loop while filtering noise and buffering the signal. --- ### 3. Detailed Hardware Features * **Ultra-Slim Design:** The housing is only **5.9 mm wide**, allowing for significant space savings on a DIN rail. * **Response Time:** Typically $\leq 25$ ms (0 to 90%), making it suitable for standard process control loops. * **Dielectric Strength:** Usually rated at 2000V AC @1 minute (Input to output to power). * **Load Resistance:** * Output 1: Max 550 $\Omega$ * Output 2: Max 550 $\Omega$ --- ### 4.
