QD-10 multi-range current input for flexible selection. Covers 0-5A to 600A options for different project current loops.

Multi-range Current Input for Flexible Selection

Covers 0–5A, 10A, 20A, 30A, 50A, 100A and 600A options.

The QD-10 AC/DC current transmitter is engineered to provide practical versatility for diverse industrial monitoring applications. By offering a comprehensive selection of input ranges—specifically covering 0–5A, 10A, 20A, 30A, 50A, 100A, and up to 600A—this single product series can easily adapt to various current loops within a project. Whether measuring small branch circuits, standard equipment feeders, or larger main power lines, the QD-10 series delivers precise signal conversion without requiring a change in the module's physical footprint.

QD-10 compact DIN rail design. DIN35mm rail mounting for multi-module cabinet installation while keeping signal conversion organized.

Compact DIN Rail Design

DIN35mm rail mounting for multi-module cabinet installation.

In modern industrial automation, control cabinet space is often highly limited. The QD-10 current transmitter addresses this challenge with its highly efficient, space-saving DIN35mm rail-mounted design. Specifically developed for high-density installations, this compact structure allows multiple modules to be neatly organized side-by-side without the need for custom mounting brackets or additional backplates. When multiple current loops require monitoring within a confined space, the QD-10 maximizes the available rail area while maintaining clear separation between power and signal lines.

QD-10 low power for long-term monitoring. 24VDC external power and <1W power consumption with three-way isolation and low temperature drift.

Low Power for Long-term Monitoring

24VDC external power and <1W power consumption.

Reliability in continuous monitoring systems heavily depends on thermal management and energy efficiency. The QD-10 current transmitter operates on a standard 24VDC external power supply and features a low power consumption of less than 1W. This energy efficiency plays a critical role in reducing the overall thermal load within enclosed control cabinets, especially when dozens of modules are installed in close proximity. Lower thermal load directly translates to a more stable environment for all surrounding electronics.
