If your facility relies on a Rockwell 1609-B or 1609-D UPS to safeguard critical equipment from power disruptions, it’s time to take action. Rockwell Automation has officially discontinued these models, meaning that once your current unit reaches the end of its lifecycle, repair services will no longer be available. Without a proper plan in place, an unexpected UPS failure could lead to costly downtime and operational inefficiencies.

Since Rockwell has chosen not to offer a direct replacement for these models, many users night be wondering what their options are. Questions about which models were affected, how this impacts current users, and which alternatives provide the best protection are now top of mind for facility managers and engineers alike.
At HESCO, an authorized distributor of Rockwell Automation products, we want to help you consider replacement options for the discontinued Rockwell 1609 units. This article will do just that, helping you to ensure continued power protection and avoid unnecessary disruptions in your operations.
What You Need to Know
Rockwell Automation’s decision to discontinue the 1609-B and 1609-D series was driven by the obsolescence of key components, making it impossible to continue manufacturing these units. As a result, several models have been phased out, with discontinuation dates spanning from June 2022 to February 2024.
The first round of discontinuations occurred on June 30, 2022, when Rockwell officially ended production of the 1609-D600N, 1609-D1000N, and 1609-D1500N, along with the 1609-AKT-DC-POWER-SUPPLY-UPS-MS. This was followed by the December 15, 2022, phase-out of the 1609-D1500E. Finally, on February 16, 2024, Rockwell ceased production of multiple 1609-B and 1609-D models, including the 1609-B600E, 1609-B600N, 1609-B1000E, and 1609-B1000N, as well as the 1609-D600E and 1609-D1000E. Accessories such as the 1609-ENET (Ethernet module), 1609-EXBAT (external battery), and 1609-SPD (surge protector) were also discontinued.
For facilities that still rely on these units, this change presents significant challenges. Repair services for these discontinued models will no longer be available, which means that if a unit fails, it must be replaced rather than serviced. While Rockwell has confirmed that battery replacements, such as the 1609-HBAT and 1609-SBAT, will still be available, supply may become limited as demand increases. Additionally, while Rockwell will continue providing firmware downloads for the 1609-D models, there is no guarantee of long-term support.
The most critical aspect of this announcement is that Rockwell is not introducing a new UPS series to replace the 1609 models. Instead, they are directing customers to consider third-party replacements, with Tripp Lite being their primary recommendation. However, if you’re a manufacturer affected by these discontinuations, there are other options you can consider.
The Best Replacement Options for You
Since Rockwell is not offering a direct replacement for the 1609 series, customers must turn to other manufacturers for alternative UPS solutions. Fortunately, both Tripp Lite and Sola HD provide reliable replacements that match or exceed the performance of the discontinued Rockwell units. These options ensure continued protection against power interruptions while integrating smoothly into existing automation systems.
One of the most suitable replacements is the Tripp Lite DIN500AC, which serves as a strong alternative for the 1609-B600N and 1609-B600E. This UPS is designed for DIN rail mounting and provides 120V input with a 10A output, making it a solid choice for industrial automation applications. With a higher power capacity than the discontinued 1609-B600N, it ensures enhanced reliability for facilities looking to maintain uninterrupted operations.

For users who previously relied on the 1609-B1000N and 1609-B1000E, the Tripp Lite DIN850AC is an excellent replacement. With a power rating of 850VA (510W), this model supports critical automation systems while offering RS-485 communication, which helps maintain some of the functionality lost with Rockwell’s discontinued models.
In addition to Tripp Lite, Sola HD’s SDU Series is another viable replacement option, particularly for customers seeking flexibility and extended battery life. The SDU500A and SDU850A models provide 500VA and 850VA output options, catering to a range of power needs. These UPS systems also feature expandable battery packs, allowing users to increase their backup time as required. With strong surge protection and industrial-grade durability, they offer a compelling alternative for Rockwell users looking for a robust, long-term solution.

Key Considerations When Choosing a UPS Replacement
Choosing the right UPS replacement is not simply a matter of picking the most powerful model. Several factors must be considered to ensure compatibility with existing systems and long-term reliability.
First and foremost, facilities should assess their power requirements by examining the VA (Volt-Ampere) and Wattage ratings of their current Rockwell UPS. Selecting a replacement that meets or exceeds these specifications is crucial for maintaining uninterrupted power protection.
Another important consideration is mounting compatibility. Many Rockwell 1609 units were DIN rail-mounted, so users should ensure that their replacement UPS can be installed in the same manner. Both Tripp Lite’s DIN series and Sola HD’s SDU Series offer DIN rail mounting options, making them well-suited for users transitioning from Rockwell’s discontinued models.
Communication and integration capabilities also play a key role in the selection process. Some users may require EtherNet/IP or RS-485 communication, which was supported by certain Rockwell 1609 models. The Tripp Lite DIN850AC provides RS-485 connectivity, making it a strong option for those needing to maintain remote monitoring and control functionality.
Finally, it is essential to consider long-term support and availability. Since the Rockwell 1609 series is already discontinued, remaining accessories and battery replacements will become increasingly scarce. Transitioning to a Tripp Lite or Sola HD UPS now ensures continued manufacturer support, minimizing the risk of supply shortages in the future.
Don’t Wait Until It’s Too Late
With Rockwell’s 1609-B and 1609-D UPS models now discontinued, facilities that depend on these systems must act quickly to secure a reliable replacement. Waiting until a UPS failure occurs could result in costly downtime, equipment damage, and operational disruptions. By proactively selecting and installing a Tripp Lite or Sola HD UPS, businesses can ensure continued protection against power fluctuations and avoid unexpected system failures.
To begin the transition, users should identify their current Rockwell UPS model, evaluate their power and installation needs, and compare the recommended replacement options. Consulting with a trusted distributor or UPS specialist can also help determine the best solution for specific facility requirements.
By planning ahead and making the switch to a supported UPS solution now, facilities can maintain seamless power protection and avoid the risks associated with operating obsolete equipment.
