Allen-Bradley 150-F60NBRD Replacement for SMC Flex

Product Overview

Allen-Bradley 150-F60NBRD Replacement for SMC Flex: Seamless Transition from Legacy Motor Control Systems

When your existing Allen-Bradley SMC Flex system reaches end-of-life or a critical unit fails on the production floor, unplanned downtime becomes your most expensive problem. The Allen-Bradley 150-F60NBRD is a 60A Smart Motor Controller from the SMC Flex series, designed for soft-start and soft-stop motor control with integrated DeviceNet communication. At TOPNLMS, we supply verified replacement and upgrade units for the 150-F60NBRD to support engineers and procurement teams managing legacy Rockwell Automation control architectures.

Whether you are replacing a failed unit in an existing SMC Flex panel, migrating from an older SMC-2 or SMC-3 series controller, or consolidating a multi-drive cabinet that previously relied on discrete contactors and overload relays, the 150-F60NBRD provides a direct upgrade path with minimal rewiring and no PLC program restructuring in most applications.

Seamless Upgrade Solutions

A successful migration from a legacy motor control system to the 150-F60NBRD rarely involves a single component swap. In practice, field engineers upgrading from SMC-2 or SMC-3 platforms typically need to address the broader control architecture at the same time.

On the network side, the 150-F60NBRD communicates natively over DeviceNet, which means your upstream controller — typically a ControlLogix or CompactLogix PLC such as the 1756-DNB DeviceNet Scanner or 1769-SDN CompactLogix DeviceNet Scanner — must have an available DeviceNet node address and a correctly configured EDS file loaded in RSNetWorx. If your existing backplane is already running a 1756-L series ControlLogix processor with a DeviceNet bridge, the integration is straightforward. For older systems still using a PLC-5 or SLC 500 as the host controller, a gateway or protocol converter may be required before the DeviceNet node can be addressed correctly.

Inside the motor control center (MCC) or control cabinet, the 150-F60NBRD’s internal bypass contactor eliminates the need for a separate external bypass contactor that was mandatory in SMC-2 installations. This directly reduces the number of components in the cabinet and frees up panel space — a significant advantage when retrofitting existing enclosures where DIN rail and wire duct space is constrained. The 1492-J series terminal blocks commonly used in Rockwell panel builds are compatible with the 150-F60NBRD’s control wiring terminals, simplifying the rewiring process.

For power supply requirements, the 150-F60NBRD’s 24V DC control circuit is typically fed from a 1606-XLP series power supply or equivalent 24V DC rail already present in most modern Allen-Bradley control panels. If the existing panel uses 120V AC control voltage, the 150-F60NBRD supports both, so no transformer change is required in most cases.

On the I/O side, discrete status outputs from the 150-F60NBRD — including run, fault, and at-speed signals — can be wired directly to available 1756-IB16 or 1769-IQ16 digital input modules in the host PLC rack, maintaining the same signal mapping used by the predecessor SMC unit. If the application requires analog feedback such as motor current or power factor monitoring, the 150-F60NBRD’s DeviceNet messaging handles this natively, reducing the need for additional analog I/O modules.

For applications where the 150-F60NBRD is being installed as part of a broader drive and motor control upgrade — for example, alongside PowerFlex 40 or PowerFlex 70 variable frequency drives on the same DeviceNet segment — the network topology and node addressing must be planned carefully to avoid address conflicts and ensure deterministic scan times. TOPNLMS can supply both the 150-F60NBRD and compatible DeviceNet trunk cable assemblies and drop cables to support a complete panel build or retrofit.

Where an HMI such as a PanelView Plus 6 or PanelView 800 is used to display motor status and fault codes, the DeviceNet-sourced data from the 150-F60NBRD can be mapped through the ControlLogix tag database to the HMI display without additional programming overhead, provided the RSLogix 5000 or Studio 5000 project is updated to include the new SMC Flex Add-On Profile (AOP).

Retrofit Guidance FAQ

Q: Can the 150-F60NBRD physically replace an SMC-2 (150-A series) unit in the same panel cutout?
A: In most cases, yes. The SMC Flex 150-F series shares a similar panel footprint with the SMC-2 for equivalent current ratings. Minor bracket or DIN rail adapter adjustments may be needed depending on the original enclosure design. Verify the mounting hole pattern against your existing panel drawing before ordering.

Q: Do I need to rewrite my PLC program when replacing an SMC-2 or SMC-3 with the 150-F60NBRD?
A: If the legacy unit was hardwired (no network communication), the PLC program changes are minimal — typically limited to updating fault and status rung logic. If the legacy unit used Remote I/O or DH-485, a more significant program revision is required to migrate to DeviceNet messaging. The SMC Flex AOP for Studio 5000 simplifies this process considerably.

Q: Is the DeviceNet wiring from my existing SMC-3 installation reusable?
A: Yes, provided the existing DeviceNet trunk and drop cables meet the standard 5-wire DeviceNet specification (24V power, ground, CAN_H, CAN_L, shield). The 150-F60NBRD uses a standard DeviceNet micro connector, compatible with existing Belden 3082A or equivalent trunk cable.

Q: What happens to the motor overload settings during replacement?
A: The 150-F60NBRD has an integrated electronic overload. You will need to configure the full-load ampere (FLA) setting via the DeviceNet network or the optional parameter module. Document the existing overload relay settings before removal and replicate them in the SMC Flex parameter set during commissioning.

Q: How much panel space does the 150-F60NBRD require compared to an SMC-2 with external bypass?
A: The 150-F60NBRD with internal bypass (N-type) typically requires less total panel space than an SMC-2 paired with a separate external bypass contactor and overload relay. This is one of the primary space-saving advantages of the SMC Flex platform in retrofit applications.

Q: Can the 150-F60NBRD be commissioned without RSNetWorx for DeviceNet?
A: Basic operation can be configured using the optional SMC Flex Parameter Module (150-SM1) for local parameter access. However, full DeviceNet node commissioning and network integration require RSNetWorx for DeviceNet and a compatible DeviceNet interface on the host controller.

Warranty Assurance

Every Allen-Bradley 150-F60NBRD unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes a pre-shipment functional inspection to verify power-on status, communication port integrity, and parameter module interface operation. Units are packed in anti-static protective packaging with foam cushioning to prevent transit damage.

In the event of a confirmed unit defect within the warranty period, TOPNLMS will arrange a replacement shipment or issue a credit note based on the buyer’s preference. Our after-sales response target is within 24 business hours of a warranty claim submission. Replacement units are dispatched from our Xiamen warehouse, with DHL Express, FedEx International Priority, or sea freight options available depending on urgency and destination.
