Why Choose the Original Model
- Native DeviceNet integration — seamless communication with Allen-Bradley PLCs and ControlLogix/CompactLogix systems
- Internal bypass contactor — reduces heat generation and extends service life after motor reaches full speed
- Dynamic braking — controlled motor stop for applications requiring precise stopping (conveyors, hoists, pumps)
- SMC-Flex advanced features — pump control, soft stop, current limit, and kickstart modes in one unit
- Full Rockwell ecosystem support — Studio 5000, RSLogix 5000, and FactoryTalk integration
Typical Applications
- Centrifugal pumps and compressors
- Conveyors and material handling systems
- HVAC fans and blowers
- Mixers and agitators
- Crushers and mills requiring controlled starting
- Water treatment and municipal infrastructure
System Compatibility
- PLC Platforms: ControlLogix, CompactLogix, MicroLogix (via DeviceNet scanner)
- Networks: DeviceNet (built-in), optional EtherNet/IP with add-on module
- Software: RSLogix 5000 / Studio 5000, RSNetWorx for DeviceNet
- Motor Types: Standard AC induction motors, 3-phase
- Bypass: Internal bypass rated for continuous duty
Selection Guide
Use the table below to select the correct 150-F2xx series model based on your application requirements:
| Requirement | Recommended Suffix | Example Model |
|---|---|---|
| DeviceNet communication | N | 150-F201NBDB |
| Internal bypass needed | B | 150-F201NBDB |
| Dynamic braking required | DB | 150-F201NBDB |
| No communication needed | (omit N) | 150-F201BD |
| Lower current (97 A) | — | 150-F97NBD |
| Higher current (361 A) | — | 150-F361NBD |
Tip: If your application does not require dynamic braking, consider the 150-F201NBD to reduce cost. If DeviceNet is not used in your network, the 150-F201BD is a cost-effective alternative.

Replacement & Compatibility FAQ
Q: Can the 150-F201NBDB replace a 150-F201NBD?
A: Yes. The 150-F201NBDB adds dynamic braking capability. It is a drop-in upgrade if your panel has space and wiring for the DB terminals.
Q: Is the 150-F201NBDB compatible with ControlLogix?
A: Yes, via a DeviceNet scanner module (e.g., 1756-DNB) in the ControlLogix chassis.
Q: Can I use a Siemens 3RW44 as a replacement?
A: Functionally yes for soft-start duty, but DeviceNet communication and Rockwell software integration will not be available. Rewiring and parameter reconfiguration are required.
Q: What is the warranty on units from Konmask.com?
A: We offer a 12-month warranty on all genuine Allen-Bradley units. Refurbished units carry a 6-month warranty. Contact us for details.
Q: Do you provide installation support?
A: Yes. Our technical team can provide wiring diagrams, parameter setup guides, and remote commissioning support.
