The TRU Voltage Transducer, developed by Borna Electronics, is a high-accuracy signal conditioning device designed to convert AC and DC voltage signals into industry-standard analog control signals. Featuring optical isolation, excellent noise immunity, and high measurement accuracy, the TRU provides reliable signal conversion for instrumentation, process control, and industrial automation applications.
The transducer accepts AC or DC voltage inputs up to 600 V and converts them into standardized analog outputs such as 0–10 VDC, 0–20 mADC, or 4–20 mADC. Its high insulation strength and low conversion error make it suitable for demanding industrial environments.
