Veris Industries H-721LC Transducer

The Veris Industries H-721LC Transducer, also recognized as the H721LC, is a high-performance solid-core current transducer engineered for precise load trending in industrial and commercial HVACR applications. This analog current sensor features a loop-powered 4-20mA output, eliminating the need for a separate power supply and simplifying your wiring architecture to a standard two-wire configuration. Designed for maximum versatility in the field, the unit integrates a factory-calibrated slide switch that allows technicians to select between 0-10A, 0-20A, or 0-40A measurement ranges without the use of jumpers.

Built for the rigors of mechanical rooms, the Veris Hawkeye H721LC utilizes solid-state sensing technology to provide accurate amperage monitoring for fan and pump status or motor control. The compact solid-core current sensor includes a 1.1-inch window and a removable, adjustable mounting bracket that ensures flexible alignment and secure installation within electrical enclosures. With an accuracy of +/- 2% of full scale, this transducer is a reliable solution for technicians requiring real-time current data for building automation systems (BAS) and direct digital control (DDC) panels.

Key Benefits

• Three Field-Selectable Ranges: Quickly adjust between 10A, 20A, and 40A via a slide switch for high-resolution monitoring.
• Reduced Installation Costs: The loop-powered 4-20mA transducer requires only two wires, lowering commissioning time and material expenses.
• Durable Solid-State Design: No moving parts ensures long-term reliability in high-vibration HVACR environments.
• Simplified Mounting: Features an adjustable/removable bracket for easy installation even in tight electrical panels.
• Broad Compatibility: Seamlessly integrates with standard building controllers and data acquisition equipment.

Common Questions

What is the difference between the H721LC and H-721LC?
These are identical units; "H-721LC" is a common alternate SKU format for the Veris Industries H721LC solid-core transducer.

How do I monitor loads below the 1A minimum rating?
To increase the sensed amperage for very small loads, wrap the conductor through the solid-core window multiple times. You must then divide the controller's reading by the number of turns to calculate the actual current.

Does this unit require an external power source?
Yes, the H-721LC requires a 12-30VDC power source in series with the 4-20mA loop to generate its clinical output signal.
