The QI-50-V-485 RS-485 Current Transducer is a compact digital AC current sensor designed for accurate current monitoring and seamless integration into industrial automation, energy monitoring, Building Management Systems (BMS), SCADA, PLC, and smart power management applications. Unlike traditional current transformers that require additional transmitters or analogue converters, the QI-50-V-485 features a built-in Modbus RTU RS-485 interface, allowing measured current values to be transmitted directly over a digital communication network.
Using a through-window current sensing design, the transducer measures AC current up to 50A without interrupting the existing electrical circuit. The conductor simply passes through the sensing aperture, making installation fast, safe, and ideal for retrofit projects. Configuration is performed directly on the device using integrated DIP switches, allowing installers to easily set measurement range, Modbus address, and baud rate without requiring specialised software or programming tools.
The RS-485 multi-drop communication capability enables multiple transducers to be connected on a single communication bus, significantly reducing wiring costs and simplifying large-scale monitoring systems. This makes the QI-50-V-485 an excellent solution for electrical switchboards, motor control centres (MCCs), energy sub-metering panels, industrial machinery, process automation, renewable energy systems, HVAC monitoring, and facility management applications.
With its compact footprint, plug-in terminal connections, and reliable Modbus communication, the QI-50-V-485 provides a simple, cost-effective method of digitising current measurements while improving data accuracy, reducing analogue signal interference, and enabling real-time monitoring across industrial and commercial installations.
