The **M2XU-R1V1-R/UL** is a specific model within the **M2XU series** of signal conditioners manufactured by **M-System**. This device is a PC-programmable, multi-input signal conditioner designed to convert various industrial input signals into a standard DC output. --- ### 1. Key Technical Specifications The "R1V1" portion of the model number defines the power input and output configurations. | Component | Specification | Details | | :--- | :--- | :--- | | **Input** | Multi-Input | Universal (DC, Thermocouple, RTD, Potentiometer, etc.) | | **Output (V1)** | DC Output | Range: 0 – 10V DC | | **Power Input (R)** | 24V DC | Range: 24V DC ±10% | | **Standards** | UL/cUL | Approved for North American safety standards | | **Programming** | PC Configurable | Parameters set via M-System’s software | --- ### 2. Electronic Architecture The internal circuitry is designed for high precision and industrial-grade isolation. * **Isolation Barrier:** The device features **three-way isolation** (Input to Output to Power). This prevents ground loops and protects sensitive PLC/DCS equipment from high-voltage surges on the field side. * **A/D and D/A Conversion:** It utilizes a high-resolution Analog-to-Digital converter for the universal input and a Digital-to-Analog converter for the 0-10V output, ensuring high linearity. * **Microprocessor Control:** The internal CPU handles linearization (especially for thermocouples and RTDs) and digital filtering to stabilize noisy signals. * **Protection:** Includes overcurrent protection and surge suppression compliant with industrial electromagnetic compatibility (EMC) standards. --- ### 3. Connection Pinout (Typical) While you should always consult the manual for the specific wiring diagram, the M2XU series generally follows this block structure: | Terminal No. | Function | Description | | :--- | :--- | :--- | | **1 - 4** | Input | Connections for mV, V, TC, or RTD | | **5 - 6** | Output | 0 – 10V DC (V1 configuration) | | **7 - 8** | Power | 24V DC (R configuration) | --- ### 4. Applications * **Temperature Monitoring:** Converting a Type K thermocouple signal to a 0-10V signal for a PLC. * **Signal Leveling:** Converting a non-standard DC voltage from a sensor into a standard industrial range. * **System Protection:** Providing a physical break (isolation) between field sensors and a central control system.
