The 150-S251NUD controller is an Allen-Bradley controller with an integrated internal bypass. The product line to which the 150-S251NUD controller belongs is the SMC-50 product line, which is a series of smart motor controllers designed for motor starting. The 150-S251NUD controller is available in an open enclosure and it dissipates 93 Watts as heat during operation. The recommended temperature ranges for the storage and operation of the 150-S251NUD controller are from -13 to 167 degrees Fahrenheit and -4 to 122 degrees Fahrenheit, respectively. The recommended range of non-condensing relative humidity is 5 to 95%. The controller should be installed at altitudes that are less than or equal to 2000 meters. At higher altitudes, the controller output will derate. The 150-S251NUD controller is designed for vertical mounting.
The input voltage range is 200 to 690 Volts AC. Three-phase input voltage is supported at 50 to 60 Hertz line frequencies. The output current rating of the 150-S251NUD controller is 251 Amps. The control voltage rating is 100 to 240 Volts AC. Integrated I/Os on the controller include two 24 Volts DC rated inputs and two relay outputs. Optional communication modules can be used to enable network communication, and these include DeviceNet, ControlNet, Profibus DP, and RS-485 modules. Four integrated DPI interfaces are available for local serial communication. The operational and non-operational shock ratings for the 150-S251NUD controller are 5.5 G and 25 G, respectively. The operational and non-operational vibration ratings for the controller are 1 G peak and 2.5 G peak, respectively. The 150-S251NUD controller is certified by the CCC, EMC, KCC, ABS, and CE standards. The approximate dimensions of the controller are 38 x 30 x 14 inches.
