Based on the model number **M2VF2-B3-R2/UL**, this device is a high-performance **M-System M2 Series Signal Conditioner**. Specifically, it is a variable output transmitter designed to convert a standard DC input into a different, isolated DC output. --- ### 1. Component Specifications The alphanumeric code identifies the specific electrical configuration of the unit: | Code Segment | Description | Specific Detail | | :--- | :--- | :--- | | **M2VF2** | Model Series | M2 Series Signal Conditioner (Variable Output) | | **B** | Power Input | 100 – 240V AC (50/60 Hz) | | **3** | Input Signal | 0 – 1V DC | | **R2** | Output Signal | 4 – 20mA DC (with variable adjustments) | | **UL** | Certification | UL/cUL recognized component | --- ### 2. Key Electronic Features The M2VF2-B3-R2/UL is built with industrial-grade electronic parts to ensure signal integrity: * **Isolation Circuitry:** It features **3-port isolation** (Input to Output to Power). This prevents ground loops and protects sensitive PLC/DCS inputs from high-voltage surges on the power line or input side. * **Zero/Span Adjustments:** The front panel contains multi-turn potentiometers. These allow fine-tuning of the output range (e.g., ensuring 4mA corresponds exactly to 0V input). * **Dielectric Strength:** Capable of withstanding 2000V AC for one minute (Input to Output to Power to Ground). * **Operating Indicator:** Includes a front-facing LED that indicates the power status and basic health of the internal PCB. --- ### 3. Physical & Wiring Layout The unit uses a plug-in base structure for easy maintenance. | Terminal | Connection Type | | :--- | :--- | | **1 & 2** | Output Signal (4-20mA) | | **3 & 4** | No Connection / Shield | | **5 & 6** | Input Signal (0-1V) | | **7 & 8** | Power Supply (100-240V AC) | ### 4. Technical Performance * **Accuracy:** ±0.1% of span. * **Response Time:** ≤ 0.5 seconds (0 – 90%). * **Load Resistance:** Up to 750 $\Omega$ for the 4-20mA output. * **Construction:** Flame-resistant black resin housing. ---
