The **W2XM-1V2V2-R** is a specific model of an **isolated signal conditioner** (specifically a signal splitter) manufactured by **M-System**. It is designed to take one analog input signal and provide two independent, isolated analog output signals. --- ### 1. General Specifications This device is part of the M-System W2 Series, which is known for its compact, plug-in style design used in industrial automation. | Feature | Specification | | :--- | :--- | | **Model Function** | Dual Output Signal Conditioner (Splitter) | | **Input Type** | 0 – 1V DC | | **Output 1** | 0 – 1V DC | | **Output 2** | 0 – 1V DC | | **Power Input** | 24V DC (Indicated by the "R" suffix) | | **Isolation** | 4-way isolation (Input to Output 1 to Output 2 to Power) | --- ### 2. Breakdown of the Model Code The alphanumeric string defines the internal electronic configuration: * **W2XM**: Series identifier (Dual-output signal conditioner). * **1**: Input Signal (0 – 1V DC). * **V2**: Output 1 Signal (0 – 1V DC). * **V2**: Output 2 Signal (0 – 1V DC). * **-R**: Power Supply (24V DC). --- ### 3. Key Electronic Components & Functions The internal circuitry is composed of several critical stages to ensure signal integrity: #### A. Input Stage (Signal Conditioning) The device receives the 0-1V DC signal. High-impedance op-amps are used to ensure the device does not "load" the source sensor or transmitter, maintaining the accuracy of the original voltage. #### B. Isolation Barrier This is the most critical part of the W2XM. It uses **Optical or Transformer isolation**. This protects the control system from: * Ground loops. * High-voltage surges on the field side. * Signal noise interference. #### C. Splitter & Output Stage The isolated signal is split into two independent paths. Each path has its own calibration potentiometers (usually accessible on the front panel) for: * **Zero Adjustment:** Fine-tuning the 0V offset. * **Span Adjustment:** Fine-tuning the 1V gain. #### D. DC-to-DC Converter Since the device is powered by 24V DC (the "-R" suffix), it contains an internal switching regulator that converts the input power into various isolated voltage rails to power the internal op-amps and isolation circuits. --- ### 4. Technical Summary Table | Parameter | Value | | :--- | :--- | | **Accuracy** | ±0.1% of span | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation Resistance** | 100 MΩ or more (500V DC) | | **Dielectric Strength** | 2000V AC @ 1 minute | | **Mounting** | DIN Rail or Surface Mount |
