Veris Industries H-931 Current Transducer

The Veris Industries H-931 Hawkeye is a high-performance split-core current transducer engineered for precision monitoring in commercial and industrial HVACR environments. This analog current sensor features a selectable amperage range of 0-30A, 0-60A, or 0-120A, providing a linear 4-20mA output proportional to the monitored current. The integrated Command Relay (SPST, 10A @ 125VAC) allows for direct control of auxiliary equipment, reducing the need for additional hardware and simplifying wiring within busy control cabinets. Its split-core design, featuring a 1.1 x 0.8 inch aperture, facilitates seamless installation on existing conductors without disconnecting lines. Designed for reliable building automation system (BAS) integration, the H931 ensures accurate performance tracking and load trending for motors, fans, and pumps. This induction-powered unit eliminates the requirement for an external power supply for the current sensor, enhancing system efficiency and long-term stability in demanding mechanical applications.

Key Benefits:

• Versatile Range Selection: Field-selectable slides for 30A, 60A, and 120A ranges ensure precise scaling for varied motor loads.
• Integrated Control Relay: Combines sensing and switching functionality into a single device to save enclosure space and installation time.
• Split-Core Convenience: The easy-to-install split-core housing allows for retrofitting onto active circuits without downtime.
• Zero Maintenance Design: Being self-powered by the induced current from the monitored line, it reduces points of failure.
• High Compatibility: Fully compatible with PLC, DDC, and SCADA systems accepting standard 4-20mA signals.

Common Questions:

How do I set the amperage range on the H-931?
The unit features a mechanical slide switch located on the side of the housing. You can select between the 30A, 60A, or 120A scales to match the expected full-load amperage of your equipment for maximum 4-20mA resolution.

Does the relay require external power to operate?
Yes, while the 4-20mA current sensor is induction-powered, the integrated command relay requires external excitation (typically 24VAC/DC) to actuate the contacts.

Is the H-931 compatible with VFD-driven motors?
This transducer is designed for 50/60Hz sinusoidal wave monitoring. For Variable Frequency Drive (VFD) applications where frequency modulation occurs, verify the primary conductor frequency remains within the calibrated 50-60Hz window for accurate output.
