Product Description

The YDBH0.66-30I-A-200/5A CT is a compact 200/5A Current Sensor designed for precise low-voltage monitoring in industrial energy systems. Built around the YDBH0.66 Low Voltage Transformer platform, it features a single current input and analog/digital output options, supporting direct integration with up to 8 auxiliary modules through RS-485 (Modbus RTU) communication. Operating within 85-264V AC and -25°C to +70°C, it delivers 0.5% accuracy for applications in power distribution, motor control, and renewable energy installations. The sensor includes a 1.5-inch LCD for real-time data display and requires no internal battery, relying on loop-powered operation. Its non-contact design enables safe measurement at 10mm detection distance from conductors. While offering IP54-rated durability and DIN-rail mounting compatibility, its fixed 200/5A ratio limits flexibility compared to adjustable sensors. Ideal for retrofit projects, this device excels in space-constrained environments requiring reliable current monitoring.
