DVL500-UI Isolated Voltage Sensor — Silent Guardian of Industrial Precision‌

DVL500-UI ‌Core Features: Precision Isolation, Industrial-Grade Reliability‌

‌±0.5% Measurement Accuracy‌: Leveraging digital isolation technology, the DVL500-UI delivers ultra-precise DC and pulsed voltage sampling — critical for feedback control in renewable energy and automation systems, outperforming traditional voltage dividers.

‌>3 kV Electrical Isolation‌: Complete galvanic separation between high-voltage primary and low-voltage secondary circuits eliminates ground loops and protects sensitive control electronics — certified to ‌IEC 61010 CAT III‌ safety standards.

‌4–20 mA Current Loop Output‌: Native analog current output ensures superior noise immunity over long distances — up to 1 km — with seamless integration into PLCs, DCS, and SCADA systems without additional signal conditioning.

‌Extended Operating Temperature Range‌: Functions reliably from ‌-40°C to 85°C‌, making it ideal for harsh environments — from Arctic wind farms to high-temperature industrial ovens and outdoor photovoltaic arrays.

‌Panel-Mount Design with M5 Screw Terminals‌: Compact form factor enables direct mounting inside control cabinets. Quick-connect M5 terminals reduce installation time by over 50% and ensure secure, vibration-resistant wiring.

‌Single-Supply, Low-Power Operation‌: Powered by ‌15–24 V DC‌, with static consumption under ‌150 mW‌ — minimizing heat generation and extending system lifespan in dense control panels.
