The **M2VF-BZ-R/N** belongs to the **M2VF Series** of ultra-slim signal conditioners (transducers) manufactured by **M-System** (now often branded as MG CO., LTD). This specific model is a **Variable Output Signal Conditioner** designed for high-density mounting in industrial control panels. --- ### 1. Model Code Breakdown The suffix determines the specific input/output and power configurations: | Code Segment | Description | Specific Detail | | :--- | :--- | :--- | | **M2VF** | Series Name | Ultra-slim Signal Conditioner | | **BZ** | Input/Output Type | **B:** 4 – 20 mA DC Input / **Z:** 0 – 10 V DC Output* | | **R** | Power Input | 24V DC | | **N** | Standards/Options | No CE marking (standard industrial version) | *\*Note: Always verify with the specific datasheet as "Z" can sometimes denote a custom range specified at the time of order.* --- ### 2. Electronic Specifications These units are designed to provide galvanic isolation between the input, output, and power supply. * **Input Impedance:** Approximately 250 $\Omega$ (for 4-20mA input). * **Output Resistance:** 10 k$\Omega$ minimum load (for 0-10V output). * **Response Time:** $\leq$ 0.5 seconds (0 – 90%). * **Isolation:** 3-way isolation (Input to Output to Power). * **Accuracy:** $\pm$0.1% of span. * **Temperature Coefficient:** $\pm$0.015% per °C. --- ### 3. Physical & Installation Features The "Electronic" design of the M2VF series emphasizes space-saving and reliability: 1. **Ultra-Slim Profile:** Only 5.9 mm (0.23") wide, allowing for dozens of units to be mounted on a single DIN rail. 2. **Power Distribution:** Often utilizes a "Power Bus" connector on the DIN rail, reducing the need for individual power wiring to every unit. 3. **Front Indicators:** Includes a status LED (usually green) to indicate power supply health. 4. **Zero/Span Adjustments:** Multi-turn trimmers located on the front for field calibration. --- ### 4. Wiring Diagram Representation The unit typically uses tension-clamp (screwless) or screw terminals: ```text [ Input ] [ Output ] Terminal 1 (+) Terminal 3 (+) Terminal 2 (-) Terminal 4 (-) [ Power ] Terminal 5 (+) 24V DC Terminal 6 (-) 0V ``` --- ### 5. Application Use-Case The M2VF-BZ-R/N is typically used to interface a **PLC (Programmable Logic Controller)** that requires a 0-10V signal with a **Field Sensor** that outputs a 4-20mA current loop. It protects the PLC from ground loops and electrical noise while performing the signal conversion.
