Veris Industries is an energy and environmental sensor partner that provides quality products for commercial HVAC and other automation applications. We offer complete lines of reliable, long-lasting innovative power monitoring products.

The Hawkeye 5xx series combines an industrial-grade load switching relay, current status switch in an easy-to-install remote enclosure making the series ideal for monitoring, directly controlling, and troubleshooting the control wiring of fractional horsepower motors. The relay, current sensor are combined in a series circuit. Once a 500 is wired in series between the power source and motor, all three components are installed. The housing provides physical separation and multiple wiring exits to isolate control and high voltage wiring. A 500 can be mounted directly on 2 or 4 gang junction boxes, nippled to a field enclosure, or stand-alone.
