The **M2VT-163-R** is a high-performance **Signal Conditioner** (specifically a Transducer/Potentiometer Transmitter) manufactured by **M-System**. It is designed to convert resistance or potentiometer signals into standard DC voltage or current signals. --- ### 1. Key Technical Specifications The following table highlights the core electronic characteristics of the M2VT-163-R: | Feature | Specification | | :--- | :--- | | **Primary Function** | Potentiometer / Resistance Transmitter | | **Input Signal** | 100 $\Omega$ to 10 k$\Omega$ (Total resistance) | | **Output Signal** | 4 – 20 mA DC | | **Power Input** | 24V DC (approx. 10% ripple) | | **Accuracy** | $\pm$0.1% of span | | **Response Time** | $\leq$ 0.5 seconds (0 – 90%) | | **Isolation** | 3-way (Input to Output to Power) | | **Mounting** | DIN Rail Mounting | --- ### 2. Electronic Components & Design The device is built using industrial-grade solid-state components to ensure reliability in harsh environments. * **Front-End Conditioning:** Utilizes a high-precision excitation voltage circuit to measure the position of the potentiometer without introducing significant loading errors. * **Zero/Span Adjustments:** Located on the front panel, these are multi-turn potentiometers (trimmers) that allow for fine-tuning the electronic output offset and gain. * **Isolation Barrier:** Features internal optoisolators or magnetic transformers that provide up to **2000V AC** isolation. This protects downstream PLCs or SCADA systems from surges and ground loops. * **LED Indicator:** A power LED indicates the status of the internal DC-DC converter. --- ### 3.
