The **M2VF-60-R2/CE** is a high-precision, ultra-slim signal conditioner (transducer) manufactured by **M-System**. It is specifically designed to convert a DC input signal into two isolated DC output signals. Below is a detailed breakdown of its electronic specifications and technical characteristics. --- ### 1. General Specifications | Feature | Specification | | :--- | :--- | | **Model Type** | M2VF (Ultra-slim Signal Conditioner) | | **Input Signal** | 0 – 10V DC (Standard configuration for -60 model) | | **Output 1** | 4 – 20mA DC | | **Output 2** | 1 – 5V DC (Typical for R2 configuration) | | **Power Input** | 24V DC (Indicated by 'R' in the code) | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Standards** | CE Marking compliant | --- ### 2. Key Electronic Components & Design The device is built using a combination of analog and digital processing components to ensure signal integrity: * **Input Stage:** Features a high-impedance operational amplifier circuit to prevent loading effects on the source sensor. * **Isolation Barrier:** Uses an internal **transformer-coupled isolation** method. This protects the control system from surges and eliminates ground loops between the field and the PLC. * **Power Circuitry:** Designed for low power consumption (approx. 0.8W). It includes reverse polarity protection for the 24V DC supply. * **Calibration Adjustments:** The front panel contains multi-turn potentiometers for **Zero** and **Span** adjustments, allowing the user to fine-tune the output accuracy (±10% range). --- ### 3. Connection Diagram (Internal Logic) The following table represents the typical terminal mapping for the M2-series base: | Terminal No. | Function | Description | | :--- | :--- | :--- | | **1** | Output 1 (+) | Positive 4-20mA Signal | | **2** | Output 1 (-) | Negative 4-20mA Signal | | **3** | Output 2 (+) | Positive 1-5V Signal | | **4** | Output 2 (-) | Negative 1-5V Signal | | **5** | Input (+) | Positive DC Input | | **6** | Input (-) | Negative DC Input | | **7** | Power (+) | 24V DC Positive | | **8** | Power (-) | 24V DC Negative | --- ### 4. Technical Performance * **Accuracy:** ±0.1% of span. * **Temperature Coefficient:** ±0.015% per degree Celsius. * **Response Time:** $\leq$ 0.5 seconds (0 – 90%). * **Dielectric Strength:** 2000V AC @ 1 minute (Input to output to power to ground). * **Mounting:** DIN rail mounting with a slim 5.9mm profile for high-density installation.
