The **M2VT-BC-R/CE** is a high-performance, plug-in type signal conditioner (specifically a **Voltage Transmitter**) manufactured by **M-System**. It is designed to isolate and convert DC voltage input signals into standard industrial DC output signals. --- ## 1. Technical Specifications Below is a breakdown of the key electronic specifications for this specific model: | Feature | Specification Details | | :--- | :--- | | **Model Series** | M2V Series (Mini-M Series) | | **Input Signal** | DC Voltage (Configurable, e.g., 0-10V, 1-5V) | | **Output Signal** | DC Current or Voltage (Standard industrial ranges) | | **Power Input (R)** | **24V DC** (Operational range 24V ±10%) | | **Standards (CE)** | **CE Marking** (Compliant with EMC and Low Voltage Directives) | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Construction** | Plug-in base socket mount | --- ## 2. Key Electronic Components & Functionality ### A. Signal Isolation (3-Way) The unit features internal galvanic isolation between the **input, output, and power supply**. This is critical for: * **Noise Reduction:** Preventing ground loops from interfering with sensitive PLC/DCS inputs. * **Equipment Protection:** Protecting the control system from high-voltage surges on the field side. ### B. Precision Operational Amplifiers The internal circuitry utilizes high-precision op-amps to ensure a high degree of linearity (typically **±0.1%**) and low temperature drift. This ensures that the voltage measured at the sensor is accurately represented at the controller. ### C. Zero/Span Adjustments The front panel typically includes multi-turn potentiometers (Trimmers) for: * **Zero Adjustment:** Fine-tuning the 0% point of the signal. * **Span Adjustment:** Fine-tuning the 100% point of the signal. ### D. Power Circuitry (Suffix -R) The "-R" designation indicates a **24V DC power supply requirement**. Internally, the device uses a DC-DC converter to regulate this power and provide the necessary internal voltages for the isolation barrier. --- ## 3. Order Code Breakdown Understanding the specific suffix of the M2VT-BC-R/CE: * **M2VT:** Basic Model (Voltage Transmitter) * **B:** Input (Example: 0 – 5V DC) * **C:** Output (Example: 1 – 5V DC) * **R:** Power Input (24V DC) * **CE:** European Conformity (Electromagnetic compatibility and safety standards) --- ## 4. Application Wiring The device is typically mounted on a **DIN rail** using a specialized socket. ```mermaid graph LR Sensor[DC Voltage Source] -->|Input| M2VT[M2VT-BC-R/CE] M2VT -->|Output| PLC[PLC / Controller] Power[24V DC] -->|Supply| M2VT ```
