Veris Industries H-721HC Current Sensor

The Veris Industries H-721HC is a high-performance solid-core current transducer engineered for demanding industrial and HVACR monitoring applications. This 4-20mA current sensor provides precise analog feedback, allowing building automation systems to monitor motor status and performance in real-time. Designed specifically for high-current monitoring, the H-721HC handles up to 200 Amps, making it suitable for large centrifugal pumps, heavy-duty fans, and industrial compressors. The 4-20mA output signal ensures long-distance transmission without signal degradation, a critical factor for contractors integrating devices into complex BAS (Building Automation Systems). With its loop-powered design, this sensor eliminates the need for external power supplies at the sensing point, simplifying wiring and reducing installation time. The rugged housing and high dielectric strength ensure reliable operation in high-voltage environments. By providing accurate load trending and preventative maintenance data, the H-721HC allows technicians to identify belt loss, coupling shear, or motor failure before critical system downtime occurs.

Key Benefits

• High-Resolution Monitoring: Delivers a precise 4-20mA signal proportional to the 0-200A current flow for accurate load analysis.
• Loop-Powered Efficiency: Operates using the power from the controller loop, reducing overall control circuit complexity.
• Industrial Durability: Solid-core design ensures maximum stability and accuracy in high-vibration or high-dust environments.
• Seamless Integration: Compatible with any PLC or DDC controller that accepts standard analog inputs.

Common Questions

Is the H-721HC compatible with VFD applications?
Yes, this sensor can monitor the output side of a Variable Frequency Drive, though it is optimized for constant torque loads and 60Hz waveforms. For extreme high-frequency variations, consult technical data for specific frequency response ranges.

What is the maximum amperage the H-721HC can monitor?
The H-721HC is a high-current transducer factory-calibrated for a range of 0 to 200 Amps, outputting a corresponding 4 to 20mA signal.

How do I wire this sensor into my controller?
As a loop-powered device, the H-721HC is wired in series with the power supply and the analog input of your building controller.
