- 84 x 22 mm faceplate converter designed for DC12-28 V microcurrent systems, with Rs485 and 4G output options. - Function: acts as a converter for AC voltage and current, delivering DC outputs in two ranges: 4-20 mA and 0-300 A. - Key attributes: compact size (84 x 22 mm), compatible with DC12-28 V microcurrent applications, includes Rs485 and 4G connectivity for remote communication. - Performance: supports converting AC voltage and current to a DC loop output of 4-20 mA and to a DC output of 0-300 A, enabling flexible instrumentation and control. - Compatibility and reliability: suitable for low-voltage microcurrent environments, integrates with standard RS485 networks and 4G data transmission. - Use scenario 1: remote industrial monitoring. Connect AC signals to the converter, feed a 4-20 mA process signal to a PLC or DCS, and use 4G to transmit data for remote supervision while RS485 handles local network communication. - Use scenario 2: DC microgrid or plant instrumentation. Power the device from a DC12-28 V supply, monitor current up to 0-300 A, and provide a 4-20 mA loop for local instrumentation with network access via 4G for remote monitoring. - Use scenario 3: field data collection. In locations with limited wiring, utilize 4G output for telemetry and RS485 for local device integration, while the device converts AC inputs to a stable DC 4-20 mA or high-current DC signal as required.
