The **M2VT-C3-R/CE** is a high-performance **Mini-M series signal conditioner** (specifically a V-network transmitter) manufactured by **M-System** (now MG CO., LTD). It is designed to convert AC voltage signals into standard DC process signals. --- ## 1. Technical Specifications The model code `M2VT-C3-R/CE` breaks down into specific electronic configurations: | Component Code | Description | Specifications | | :--- | :--- | :--- | | **M2VT** | Model Type | AC Voltage Transmitter (True RMS) | | **C** | Input Signal | 0 – 110V AC | | **3** | Output Signal | 0 – 1V DC | | **R** | Power Input | 24V DC | | **CE** | Standards | CE Marking compliant | --- ## 2. Key Electronic Features ### A. True RMS Conversion Unlike average-sensing transmitters, the M2VT-C3-R/CE uses **True RMS (Root Mean Square)** electronic circuitry. This allows the device to accurately measure distorted waveforms or harmonics common in industrial power lines. ### B. Isolation Architecture The device features **three-way isolation**. This electronically decouples the signal paths to prevent ground loops and protect sensitive equipment: * **Input to Output** * **Input to Power** * **Output to Power** * *Isolation Resistance:* 100 MΩ minimum at 500V DC. ### C. Performance Metrics * **Accuracy:** ±0.3% of span. * **Response Time:** Approximately 0.5 seconds (0 – 90%). * **Overload Capacity:** 200% of the rated voltage for 10 seconds. * **Permissible Load Resistance:** 1000 Ω minimum for the 1V DC output. --- ## 3. Physical & Terminal Configuration The unit is a plug-in type, making it easy to replace without disconnecting wires from the base. ### Connection Diagram (Typical) ```text [INPUT AC 0-110V] [POWER 24V DC] | | | | (4) (5) (7) (8) __________|______________|__________ | | | M2VT-C3-R/CE | |___________________________________| | | (1) (2) [OUTPUT 0-1V DC] ``` --- ## 4. Environmental and Safety Standards * **Operating Temperature:** -5 to +55°C (23 to 131°F). * **Operating Humidity:** 30 to 90% RH (non-condensing). * **Mounting:** DIN rail mounting via a dedicated socket base. * **Enclosure:** Flame-resistant resin (Color: Black).
