The **M2VF-60-R** is a specific model of a **Compact Signal Conditioner** (specifically a signal transducer) manufactured by **M-System**. Its primary function is to take a variable frequency input and convert it into a standardized analog output signal, providing electrical isolation in the process. --- ### ## Technical Specifications Breakdown The model number `M2VF-60-R` can be decoded based on the manufacturer's nomenclature: | Component Code | Description | Detail | | :--- | :--- | :--- | | **M2VF** | Model Series | Frequency Transmitter (Pulse-to-Analog) | | **60** | Input Type | Open collector, Mechanical contact, or Voltage pulse | | **-** | Output Type | *Standard configurable (often 4-20mA or 0-10V)* | | **R** | Power Input | 24V DC | --- ### ### Core Electronic Functions The device consists of several internal electronic stages to ensure signal integrity: 1. **Input Pulse Processing:** * It accepts pulses from flow meters, speed sensors, or rotary encoders. * It includes a threshold detector to filter noise and recognize pulses based on a specific voltage level or dry contact closure. 2. **Frequency-to-Voltage (F/V) Conversion:** * The heart of the unit is a micro-processor or high-precision F/V converter circuit that translates the frequency rate (Hz) into a linear DC level. 3. **Galvanic Isolation:** * The device provides **three-way isolation** (Input to Output to Power). * This prevents ground loops and protects sensitive PLC/DCS inputs from high-voltage surges on the field side. 4. **Signal Conditioning & Output:** * The raw signal is scaled and buffered to provide a stable analog signal (e.g., 4–20 mA DC). * Zero and Span adjustments are typically available via front-facing potentiometers for field calibration. --- ### ### Key Application Data | Feature | Specification | | :--- | :--- | | **Construction** | Plug-in style (socket mounted) | | **Isolation** | 2000V AC @ 1 minute | | **Response Time** | Approx. 0.5 seconds (0 to 90%) | | **Mounting** | DIN rail or Surface mount | | **Indicators** | Power LED (Green) | --- ### ### Typical Connection Diagram Concept ```mermaid graph LR A[Frequency Sensor] -->|Pulse Signal| B(M2VF-60-R) C[24V DC Power] --> B B -->|4-20mA Output| D[PLC / Controller] ```
