BO-OC Current Detector - Heater Burnout Detector Open collector output

Made in the USA

Current Detector - Heater Burnout Detector
Self powered. Also available in Triac output.

BO Detector Series Detect stalled motors or jammed conveyors with repeatability. The current detector works by sensing the AC current and activating at the specified set point. Sensing a repeatable specific trip-point, allows the detector to monitor multiple parallel loads. The BO series can detect stalled motors by sensing the out of range current. In 3-phase operation (using a delta or 4-wire-Y configuration), the Transtronics current detector allows one sensor to monitor all three phases for an unbalanced condition. Upon detection, it lights the LED and optionally activates an output. Two output versions are available: Open collector, and Triac. Options include: large pass opening and adjustable set-point. Current ranges to 100 A
