Veris Industries H-921 Current Transducer

The Veris Industries H-921 Current Transducer, also referred to as the H921, is a high-performance split-core current sensor designed for accurate load trending in industrial and commercial building automation systems. Built for the veteran technician, this loop-powered device eliminates the need for separate external power supplies by inducing energy directly from the monitored conductor to generate a proportional 4-20mA output. This 2-wire configuration significantly reduces cabling requirements and commissioning time compared to traditional 3-wire sensors.

Featuring a field-selectable amperage range of 0-30, 0-60, and 0-120A, the H921 allows for precise resolution adjustment via on-board slide switches without the hassle of external jumpers. The self-gripping iris and removable mounting bracket provide unmatched installation flexibility, securing the split-core transducer around existing conductors without interrupting the circuit. With 100% solid-state construction and a 600VAC isolation rating, this Hawkeye current transducer is engineered for motor status monitoring, fan/pump verification, and critical amperage sensing in harsh HVACR environments.

• Split-core design enables rapid retrofit installation without disconnecting lines.
• Switch-selectable ranges (30/60/120A) reduce truck stock inventory by serving multiple applications.
• Loop-powered 4-20mA signal integrates seamlessly with most BMS and PLC analog inputs.
• Removable bracket can be mounted in three different configurations or on a DIN rail (with AH01 clip).
• No moving parts ensures long-term reliability in high-vibration motor control cabinets.

• Is the H-921 compatible with low-amperage loads? For accurate readings on loads below the sensor's minimum rating, the conductor can be wrapped through the 0.8-inch window multiple times to increase the sensed current.
• Does this sensor require an external power source? No, it is a loop-powered device, inducing operating power directly from the conductor being monitored.
• How do I ensure accuracy during setup? Use the factory-calibrated slide switches to match your motor’s maximum FLA to the output scale on your controller.
