The **M2UDS-D2-R/CE** is a high-precision digital signal converter (transducer) manufactured by **M-System**. It is specifically designed to take a DC input signal and convert it into two isolated DC output signals. --- ### 1. Technical Specifications The following table summarizes the primary electronic characteristics of the unit: | Feature | Specification | |:---|:---| | **Model Series** | M2 (Mini-M) Series | | **Input Signal** | 4 – 20 mA DC | | **Output 1** | 4 – 20 mA DC (Current) | | **Output 2** | 1 – 5 V DC (Voltage) | | **Power Input** | 24V DC | | **Isolation** | 3-way isolation (Input to Output to Power) | | **Accuracy** | ±0.1% | | **Response Time** | ≤ 0.5 seconds (0 – 90%) | | **Mounting** | DIN Rail Mounting | --- ### 2. Key Electronic Components & Design The device is built using industrial-grade surface-mount technology (SMT) to ensure a compact form factor. Its internal architecture consists of: * **Isolation Barrier:** Uses high-speed optocouplers or magnetic transformers to provide 2000V AC isolation. This protects sensitive PLC/DCS inputs from ground loops and electrical surges. * **Signal Conditioning Circuitry:** Utilizes precision operational amplifiers (Op-Amps) to maintain linearity and minimize thermal drift. * **Power Management:** Includes an internal DC-DC converter to provide stable voltage rails for the internal logic, regardless of fluctuations in the 24V supply. * **Zero/Span Adjustments:** Located on the front panel, these potentiometers allow for fine-tuning the calibration of the electronic output. --- ### 3. Connection Diagram (Simplified) The terminal block configuration typically follows this electronic mapping: ```text [Terminals] [Function] 1 - 2 Output 1 (+) / (-) 3 - 4 Output 2 (+) / (-) 5 - 6 Input (+) / (-) 7 - 8 Power Supply (24V DC) ``` ### 4. Certifications The **"CE"** suffix indicates that the electronic components comply with European safety and electromagnetic compatibility (EMC) standards, ensuring it does not emit excessive electronic noise and is resilient against external interference.
