The QEED QA-VI Current & Voltage Signal Converter is a compact DIN-rail signal conditioning module designed to convert raw AC current or AC voltage signals into industry-standard analogue and digital outputs for industrial automation, energy monitoring, PLC control, and building management applications. Supporting AC current and AC voltage inputs, the QA-VI provides configurable 4–20 mA, 0–10 V, and Modbus RTU (RS-485) outputs, allowing electrical measurements to be seamlessly integrated into modern control systems.
Built with galvanic isolation between the input, output and power supply, the QA-VI protects connected equipment from electrical noise, voltage spikes and ground loops while ensuring stable and accurate signal transmission. The converter operates from a universal 15–40 VDC or 20–28 VAC supply, making it suitable for a wide variety of industrial control panels, switchboards and OEM equipment. Its slim DIN-rail housing and pluggable terminals simplify installation, commissioning and maintenance in space-constrained electrical cabinets.
Ideal for panel builders, system integrators, machine manufacturers and industrial facilities, the QA-VI enables reliable communication between sensors, electrical measurement devices and PLCs without requiring complex signal conversion hardware. Whether upgrading legacy systems, adding Modbus connectivity to analogue instruments or standardising measurement signals across automation networks, the QA-VI provides a dependable and flexible signal conditioning solution.
