BQHSX is a modular input module designed for use with the UDM35 series digital panel meters, enabling high-level DC/AC current and voltage measurements. It supports selectable current ranges of 200mA, 2A, and 5A, as well as voltage ranges of 20V, 200V, and 500V, with TRMS measurement capability for distorted sine waves. The module offers a basic accuracy of ±0.1% RDG for DC measurements and ±0.3% RDG for TRMS AC measurements (45-65Hz), with a temperature drift of ±150 ppm/°C. Featuring 4kV isolation between measuring inputs and power supply, it provides reliable performance in industrial monitoring and control applications where accurate current and voltage measurement is essential.
