The **W2TS-1BA-R2/CE** is a high-precision, ultra-slim signal conditioner (transducer) manufactured by **M-System** (now part of MG CO., LTD). It is specifically designed to convert thermocouple inputs into standard DC output signals. --- ## 1. Core Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Type** | Ultra-slim Signal Conditioner (W2 Series) | | **Input Type** | Thermocouple (Type K, E, J, T, B, R, S, C, N) | | **Output Type** | Dual Output (Independent DC signals) | | **Power Input** | 24V DC | | **Mounting** | DIN Rail (Surface mount) | | **Isolation** | 2000V AC (Input to Output to Power) | | **Accuracy** | ±0.1% (Standard for most ranges) | --- ## 2. Component Analysis & Features ### A. The "W2" Architecture The "W2" prefix indicates a **dual-output** configuration. This allows the device to take one thermocouple input and provide two isolated analog signals (e.g., one for a PLC and one for a local display) simultaneously. ### B. Cold Junction Compensation (CJC) As a thermocouple transducer, it includes internal electronic components for **Cold Junction Compensation**. This ensures that the temperature reading is accurate by compensating for the ambient temperature at the terminal block. ### C. Burnout Protection The device features a safety mechanism where, if the thermocouple wire breaks, the output signal will automatically go to a specific "Up-scale" or "Down-scale" limit (e.g., 20mA or 4mA) to alert the control system of a sensor failure. ### D. CE Marking The "/CE" suffix confirms that the electronic parts and the assembly comply with European safety, health, and environmental protection requirements (EMC Directive and Low Voltage Directive). --- ## 3.

Key Electronic Advantages * **Space Saving:** Only 12mm wide, allowing for high-density installation in control panels. * **Linearization:** The internal circuitry performs electronic linearization of the non-linear thermocouple EMF (electromotive force) curve. * **Three-Way Isolation:** Prevents noise transfer between the input sensor, the output controller, and the power supply.
