Veris Industries H-940 Switch & Relay

The Veris Industries H-940 is a high-performance split-core current switch and integrated SPDT command relay, specifically engineered for building automation systems and industrial motor control. This labor-saving combo allows technicians to monitor on/off status and execute start/stop commands in a single housing, eliminating the need for separate relay mounts and long wire runs. With a fixed trip point set at 1.5A and a monitored current range up to 200A, the H-940 is optimized for fixed loads like direct drive units, exhaust fans, and fan coils where belt loss monitoring is not a necessity. Since the unit is self-powered by the monitored conductor, installation is streamlined without the requirement for external power to the sensor. The 24 VAC/VDC command relay is electrically isolated from the switch, providing a versatile interface for DDC controllers to manage motor starters and pumps while receiving real-time status feedback through 100% solid-state circuitry.

• Reduced Installation Costs: Combines a current status sensor and relay in one device, significantly reducing space requirements and field wiring labor.
• Fixed Trip Point Reliability: Features a pre-set 1.5A setpoint, ensuring consistent performance without the need for manual on-site calibration.
• Split-Core Flexibility: The split-core housing allows for rapid retrofitting onto existing conductors without disconnecting high-voltage wiring.
• Flexible Mounting Options: Includes a removable bracket that can be installed in three different orientations or adapted for DIN rail mounting with optional clips.
• Tubing-Free Operation: Serves as a more reliable thermal alternative to differential pressure switches, eliminating the maintenance issues associated with pneumatic tubing.

Can the H-940 detect a broken belt?
No, the H-940 is a fixed-threshold unit designed to detect the presence or absence of current to determine if the motor is energized. For applications requiring belt loss detection, an adjustable trip point sensor like the Hawkeye H-908 or H-921 should be utilized.

What is the maximum voltage the sensor can monitor?
This unit is designed for use on insulated conductors with an insulation class of 600VAC RMS. It is essential to only install the device on properly insulated lines to prevent arcing or electrical hazards.

How do I monitor loads below the 1.5A minimum?
For low-amperage applications (less than 1.5A), you can increase the current detected by the sensor by wrapping the monitored conductor through the split-core window multiple times. The total sensed current is the actual current multiplied by the number of passes through the sensor.
