The **W2TS-2AC-R/N** is a specific industrial-grade signal transducer (transmitter) typically used for temperature conversion and signal conditioning in automation systems. This model is often part of the **W2 series** from manufacturers like **Watanabe Electric**. --- ### ## Technical Specifications Overview The W2TS-2AC-R/N is designed to take a Thermocouple input and convert it into a standardized analog signal. | Feature | Specification | | :--- | :--- | | **Model Type** | Thermocouple Transmitter (Thin-profile) | | **Input Signal** | Thermocouple (e.g., K, E, J, T, B, R, S) | | **Output Signal** | Dual Analog Outputs (R/N suffix often indicates specific output ranges) | | **Power Supply** | AC Power (Typically 85 - 264V AC) | | **Mounting** | DIN Rail Mounting | | **Response Time** | High-speed response (typically < 100ms) | --- ### ### Key Electronic Components & Features 1. **Cold Junction Compensation (CJC):** The internal circuitry includes a high-precision thermistor or temperature sensor at the terminal block. This compensates for the ambient temperature at the connection point to ensure accurate thermocouple readings. 2. **Galvanic Isolation:** The device features **three-way isolation** (Input, Output, and Power). This prevents ground loops and protects sensitive PLC/DCS equipment from high-voltage surges on the field side. 3. **Linearization Circuitry:** Since thermocouple voltage is non-linear relative to temperature, the internal microprocessor applies a linearization curve to ensure the output (e.g., 4-20mA or 1-5V) is proportional to the actual temperature. 4. **Burnout Protection:** The "R/N" variants usually include a burnout feature. If the thermocouple wire breaks, the electronic output will go to a specific "Upscale" or "Downscale" limit to alert the control system of a sensor failure. --- ### ### Terminal Configuration (Standard Layout) Most W2TS units follow a standardized wiring block: ```text [Input Terminals] -> Thermocouple (+ / -) [Output 1 Terminals] -> Analog Signal (e.g., 4-20mA) [Output 2 Terminals] -> Analog Signal (Secondary monitor) [Power Terminals] -> AC Power Input (L / N) ``` --- ### ### Typical Applications * **HVAC Systems:** Monitoring boiler temperatures. * **Metal Processing:** Controlling furnace heat levels. * **Food Industry:** Maintaining precise temperatures in ovens or cooling units. * **Signal Conversion:** Converting low-millivolt thermocouple signals into long-distance current loops.
