The non-invasive current sensor requires no shunt resistor or wire break, making the module suitable for industrial monitoring and data acquisition.\u003c\/p\u003e\u003cp\u003eIt operates from a 9–24 V DC supply and provides measured voltage and current over a TTL UART interface at three readings per second. The datasheet specifies 1.5 kV DC isolation between the measured voltage and communication lines. Modbus RTU slave operation requires an external TTL-to-RS485 converter.\u003c\/p\u003e\u003cp\u003eThe 80 × 36 mm board supports programmable 9600\/19200 baud rates, slave addresses 1–247, voltage and current calibration, and zero-current offset correction.\u003c\/p\u003e","brand":"VAJRAVEGHA","offers":[{"title":"Default Title","offer_id":45244088811571,"sku":"2EMK30015","price":1964.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0650\/8285\/1379\/files\/vvm311-400v-200a-isolated-voltage-current-sensor.jpg?v=1793440826","url":"https:\/\/twoelectrons.com\/products\/vvm311-400v-200a-dc-isolated-voltage-and-current-sensor-module-with-serial-uart-communication-modbus-compatible","provider":"TwoElectrons","version":"1.0","type":"link"}
