The **M2VS-DB-R2/CE** is a high-performance, ultra-slim signal conditioner (isolator) manufactured by **M-System** (part of the M2 Series). Its primary function is to receive a DC voltage input and provide an isolated DC voltage output. ### 1. Technical Specifications The model code `M2VS-DB-R2/CE` breaks down into the following specific electronic configurations: | Component | Specification | Description | | :--- | :--- | :--- | | **Model** | M2VS | Ultra-slim Signal Conditioner (Voltage Input) | | **Input** | **D** | 0 – 10V DC | | **Output** | **B** | 1 – 5V DC | | **Power Input** | **R2** | 11 – 27V DC (Ripple 10% p-p max) | | **Standards** | **/CE** | CE marking compliant (EMC Directive) | --- ### 2. Key Electronic Features * **Three-Way Isolation:** The device provides complete galvanic isolation between the **Input**, **Output**, and **Power** circuits. This protects sensitive PLC/DCS cards from ground loops and electrical surges (Isolation resistance $\ge$ 100 MΩ). * **Dielectric Strength:** Capable of withstanding 2000V AC for 1 minute between all terminals. * **Response Time:** Standard response time is $\le$ 0.5 seconds (0 – 90%). * **Adjustability:** * **Zero Adjustment:** -5 to +5% of the span. * **Span Adjustment:** 95 to 105% of the span. * **Mounting:** Designed for high-density DIN rail mounting (only 5.9mm wide). --- ### 3. Terminal Connection Layout The unit typically features a 4-terminal or 8-terminal configuration depending on the base socket used (M2BS series). | Terminal No. | Function | Description | | :--- | :--- | :--- | | 1 | Output (+) | 1 – 5V DC Signal | | 2 | Output (-) | Common | | 3 | Input (+) | 0 – 10V DC Signal | | 4 | Input (-) | Common | | 5 | Power (+) | 24V DC (+) | | 6 | Power (-) | 24V DC (-) | --- ### 4. Application Context In an industrial control system, the **M2VS-DB-R2** acts as a bridge. For example, if a sensor outputs a 0-10V signal but the controller (PLC) only accepts a 1-5V input, this electronic part performs the **scaling** and **noise isolation** simultaneously.
