The **W2TS-4AC-R2/Q** is a high-precision, space-saving signal conditioner (transmitter) manufactured by **M-System**. This specific model is designed to convert two independent DC input signals into two isolated DC output signals. --- ### ## Technical Specifications Below is a breakdown of the electronic characteristics and configurations for this specific model: | Feature | Specification | | :--- | :--- | | **Model Series** | W2TS (Two-wire Transmitter / Signal Conditioner) | | **Input Type** | 4: 0 – 10V DC | | **Output Type** | A: 4 – 20mA DC | | **Power Input** | C: 15V DC | | **Version/Option** | R2: High-speed response / Q: Optional custom specs | | **Mounting** | DIN Rail or Surface Mount | | **Isolation** | 3-Port (Input to Output to Power) | --- ### ## Core Electronic Components & Architecture 1. **Dual-Channel Circuitry**: The "W2" prefix indicates a "Double-Output" or dual-channel unit. It houses two independent signal conditioning circuits within a single narrow housing, effectively doubling the density in a control panel. 2. **Isolation Barrier**: The unit utilizes internal photocouplers or transformers to provide galvanic isolation. This prevents ground loops and protects sensitive PLC/DCS inputs from high-voltage surges on the field side. 3. **A/D and D/A Conversion**: The device samples the 0-10V analog input, processes it through a microprocessor (in modern iterations), and reconstructs a precise 4-20mA current loop output. 4. **Zero/Span Adjustments**: Located on the front panel, these potentiometers allow for fine-tuning the electronic calibration to compensate for sensor drift or line resistance. --- ### ## Key Features * **High-Speed Response (R2)**: The "R2" designation typically refers to a modified time constant, allowing the electronics to process signal changes much faster than standard industrial transmitters (often < 0.5ms or 2ms depending on exact revision). * **Compact Footprint**: Designed to minimize cabinet space, utilizing a plug-in base for easy maintenance without disconnecting wiring. * **Quality Mark (Q)**: The "/Q" suffix usually indicates a specific quality requirement, such as a certificate of compliance, special testing, or tropicalization (coating for moisture resistance). ---
