The **W2SP-2CC-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 accept a potentiometer (slidewire) input and provide two isolated DC outputs. --- ### ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Series** | W2SP (Ultra-slim, 2-output type) | | **Input Type** | Potentiometer (Slidewire) | | **Input Resistance** | 100 $\Omega$ to 10 k$\Omega$ | | **Output 1 & 2** | 4 – 20 mA DC (Configurable via suffix) | | **Power Input** | 24V DC | | **Accuracy** | ±0.1% | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Isolation** | 2000V AC (Input to Output 1 to Output 2 to Power) | | **Standards** | CE Marking | --- ### ### Component Breakdown & Features #### 1. Input Section (Potentiometer) The "2CC" in the model name indicates the input and output configuration. The device provides a constant reference voltage to a potentiometer and measures the wiper position. This is commonly used for: * Valve position feedback. * Level sensing via float-operated slidewires. * Mechanical displacement monitoring. #### 2. Signal Isolation One of the most critical "electronic" roles of this part is **four-way isolation**. It electrically separates the sensor, the two PLC/Controller inputs, and the power supply. This prevents ground loops and protects sensitive control equipment from electrical surges. #### 3. Dual Output (R2) The "R2" designation identifies the power requirement and output density. This specific module provides two independent, isolated analog outputs from a single input source. This allows you to send the same position signal to both a local display and a remote SCADA system simultaneously. #### 4. Physical Design * **Housing:** Compact, flame-resistant resin. * **Installation:** DIN rail mounting. * **Adjustments:** Front-facing Zero and Span adjustments (trimmer potentiometers) for field calibration. --- ### ### Connection Diagram (Typical) ```text [ Potentiometer ] [ W2SP-2CC-R2/CE ] [ Control System ] (Sensor) (Conditioner) (PLC/DCS) | | | High Term (1) <-----------> [ REF VOLT ] | Wiper (2) <-----------> [ MEASURE ] ----> Output 1 (4-20mA) Low Term (3) <-----------> [ COM ] ----> Output 2 (4-20mA) | [ 24V DC PWR ] ``` ---
