Product Description
The Allen-Bradley (Rockwell Automation) 150-B240NBDA is a 3-phase, solid-state SMC Dialog Plus controller with a 100-240 VAC control voltage and a 200-460 VAC, 50-60 Hz input line voltage. This open-enclosure module, rated for 460 VAC, handles 5-200 horsepower motors with a 240 Amp amperage rating. It includes a SCANport (100mA max output) for a single peripheral device and a human-machine interface with an emergency stop button. Control options include soft stop (for emergency stops), pump control (not for emergency stops, may cause overheating), preset slow speed (not for continuous operation due to reduced motor cooling), and smart motor braking.
Is Your Device Showing These Signs?
The Allen Bradley 150-B240NBDA commonly experiences issues such as nuisance tripping due to incorrect overload settings or faulty trip units. Contactor coil failures and subsequent motor control interruptions are frequent, often stemming from voltage fluctuations or coil degradation. Inspect auxiliary contacts for wear or damage, as these impact signaling and control circuit functionality. Diagnose and rectify communication errors within the DeviceNet network, ensuring proper baud rate and addressing configurations. Replace worn or damaged bimetallic overload relays to maintain accurate motor protection and prevent thermal overload conditions.
