The **W2SP-2AD-R2/CE** is a high-performance, ultra-slim signal conditioner (specifically an analog-to-digital transmitter) manufactured by **M-System**. It is designed to convert two independent DC input signals into two independent DC output signals while providing galvanic isolation. --- ## 1. Technical Specifications Overview Below are the primary electronic characteristics of the W2SP-2AD-R2/CE: | Feature | Specification | | :--- | :--- | | **Model Series** | W2SP (Ultra-slim, 2-channel output) | | **Configuration** | 2 Inputs / 2 Outputs | | **Power Input** | 24V DC (Operating range 24V ±10%) | | **Isolation** | 4-way isolation (Input 1 to Input 2 to Output to Power) | | **Standard Compliance** | CE Marking (EMC Directive) | | **Mounting** | DIN Rail | --- ## 2. Detailed Electronic Components & Functions ### A. Dual Channel Input/Output This device is a "Signal Splitter" or "Dual Transmitter." - **Input:** It typically accepts DC signals (such as 4-20mA or 1-5V). - **Output:** It reproduces these signals for downstream devices like PLCs or SCADA systems. The "2AD" code indicates the specific factory-set I/O combination. ### B. The "R2" Power Spec The **R2** suffix is critical for the internal power circuitry: - It signifies a **24V DC** power supply requirement. - It features ripple prevention and surge protection to ensure stable signal conversion even in electrically noisy industrial environments. ### C. Isolation Circuitry The device employs high-grade opto-couplers or magnetic transformers to achieve **4-way isolation**. - **Benefit:** This prevents "Ground Loops," where small voltage differences between the ground points of different equipment cause measurement errors or hardware damage. - **Dielectric Strength:** Usually rated for 2000V AC for 1 minute. ### D. CE Compliance The **/CE** suffix confirms the electronics meet European safety and electromagnetic compatibility standards: - **EMI (Electromagnetic Interference):** Low emission, won't interfere with nearby electronics. - **EMS (Electromagnetic Susceptibility):** High immunity to external radio frequencies and static discharge. --- ## 3. Terminal Connection Diagram (General) Standard wiring for this type of electronic module follows this logic: ```text [ Input 1 ] (1) (+) (5) (+) [ Output 1 ] (2) (-) (6) (-) [ Input 2 ] (3) (+) (7) (+) [ Output 2 ] (4) (-) (8) (-) [ Power ] (9) (+) 24V DC (10)(-) 0V ``` --- ## 4. Summary of Use Case You would use the **W2SP-2AD-R2/CE** when you need to send two different sensor signals into a control cabinet while ensuring that any electrical noise or surges on the field side do not reach your sensitive controller (PLC). Its ultra-slim design allows for high-density installation in cramped electrical panels.
