Why Choose the Original Model
- Native DeviceNet Integration: Seamless communication with Allen-Bradley PLCs and ControlLogix/CompactLogix systems without additional gateways.
- SMC Flex Ecosystem: Compatible with all SMC Flex accessories including bypass contactors, parameter modules, and communication adapters.
- Advanced Motor Protection: Built-in overload, phase loss, jam, stall, and underload protection reduces external relay requirements.
- Rockwell Automation Support: Full lifecycle support, firmware updates, and spare parts availability through authorized channels.
- Proven Reliability: Widely deployed in water/wastewater, HVAC, and manufacturing industries globally.
Typical Applications
- Pump soft-start and soft-stop control (water treatment, HVAC)
- Conveyor and compressor motor starting
- Fan and blower applications requiring smooth acceleration
- Industrial machinery requiring motor protection and energy savings
- OEM machine builders integrating DeviceNet networks
System Compatibility
- PLC Platforms: ControlLogix, CompactLogix, MicroLogix (via DeviceNet scanner)
- Networks: DeviceNet (native), EtherNet/IP (with 150-SM4 adapter)
- Software: RSLogix 5000 / Studio 5000, RSNetWorx for DeviceNet
- Bypass Contactors: 100-C43 or 100-C60 Allen-Bradley contactors recommended
- Parameter Module: 150-SM1 (optional, for parameter backup and copy)
Selection Guide
Use the following criteria to confirm the 150-F43NBD is the right model for your application:
- Motor FLA ≤ 43A — verify motor nameplate full-load amps
- Supply voltage: 200–480V AC 3-phase — confirm site voltage
- Control voltage: 100–240V AC — confirm control panel voltage
- DeviceNet communication required — if not needed, consider 150-F43NZD
- Open-type enclosure acceptable — if IP protection needed, install in suitable enclosure
- External bypass contactor required — size per motor FLA
If your motor exceeds 43A, consider the 150-F54NBD (54A) or 150-F72NBD (72A) as next-tier options.

Replacement & Compatibility FAQ
Q: Can I replace 150-F43NBD with 150-F43NZD?
A: Yes, the 150-F43NZD is identical except it lacks the DeviceNet communication port. If your system does not use DeviceNet, it is a direct drop-in replacement.
Q: Is the 150-F43NBD compatible with ControlLogix?
A: Yes, via a DeviceNet scanner module (e.g., 1756-DNB) installed in the ControlLogix chassis.
Q: What bypass contactor should I use?
A: Allen-Bradley 100-C43 (43A) or 100-C60 (60A) contactors are recommended for use with the 150-F43NBD.
Q: Can this unit be used with a Siemens PLC?
A: Yes, with a DeviceNet master scanner compatible with Siemens systems, or via hardwired I/O using the built-in digital inputs/outputs.
Q: Do you offer reconditioned units?
A: Yes. Please contact us for availability and pricing on factory-reconditioned 150-F43NBD units.
