The Allen-Bradley 150-S251NUD controller from the SMC-50 series is a smart motor controller designed for efficient motor starting, featuring an integrated internal bypass and a robust output current of 251 Amps. It operates within a voltage range of 200 to 690 Volts AC and supports three-phase input at 50 to 60 Hertz. This controller includes two 24 Volts DC rated inputs, two relay outputs, and supports optional communication modules like DeviceNet and Profibus DP for enhanced network connectivity. It is housed in an open enclosure, dissipates 93 Watts as heat, and is suitable for vertical mounting at altitudes up to 2000 meters. Certified to CCC, EMC, KCC, ABS, and CE standards, it is engineered to withstand operational shocks up to 5.5 G and non-operational shocks up to 25 G, with vibration ratings of 1 G peak operational and 2.5 G peak non-operational. The 150-S251NUD is built to function within a temperature range of -4 to 122 degrees Fahrenheit, ensuring reliability even in challenging conditions, and is dimensioned at approximately 38 x 30 x 14 inches.
