Product Description
The Allen-Bradley 150-S317NBD is a 317 Amp SMC-50 controller with internal bypass, designed as an open enclosure with 100W heat dissipation. It operates from -4 to 122F and stores from -13 to 167F, up to 6560 feet altitude, with pollution degree 2 and ANSI/ISA-71.04-2013 atmospheric protection. Mechanically, it withstands 1G/2.5G operational/non-operational vibration and 5.5G/25G operational/non-operational shock. It features four DPI communication ports with optional module expansion. For line-connected motors, it delivers 100W peak power at 200VAC (106-317A) and 125W at 230VAC (106-317A), reaching 250HP at 460VAC. For Wye-Delta motors, it achieves 150HP, 200HP, and 450HP at 200VAC, 230VAC, and 460VAC respectively. Supported modes include soft start, current limit start, selectable kickstart, coast-to-rest, soft stop, full voltage start, dual ramp start, pump start, slow speed with braking, torque control, energy saver, external bypass, and resistive load. Its dimensions are 51x36x14 inches.
Is Your Device Showing These Signs?
The Allen Bradley 150-S317NBD SMC Flex Smart Motor Controller commonly experiences issues such as failed SCRs, IGBT failures, and blown fuses within the power structure, leading to operational faults. Communication errors on the EtherNet/IP network are frequent, requiring inspection of the network interface and configuration parameters. Overload trips occur due to incorrect motor FLA settings or malfunctioning current transformers. Firmware corruption necessitates a reflash to restore proper functionality. Component degradation on the control board results in erratic behavior and requires component-level repair or board replacement.
