Five Ways to Rethink Enclosures for the IoT

Even in IoT applications, the enclosure continues to be a plant floor workhorse. Here are five ways to make sure your enclosures work for the IoT.

The industrial Internet of Things (IoT) impacts the ability of companies to manage data and function efficiently. With more than 300 end-to-end IoT solutions in the marketplace, it can be overwhelming for industrial engineers trying to understand IT implementation and workflows.

With all of the challenges that the IoT brings, it is important to consider that the workhorse of infrastructure remains the enclosure. Whether production equipment and controls are communicating locally or pushing data to the cloud, the enclosure is crucial to success.

Specifying additional enclosures and networking equipment without first taking stock of your existing infrastructure can impact program efficiency and opportunities to scale your operations.

In order for your operations to deliver on the promise of the IoT, the entire process, right down to existing enclosures, must be reexamined to assure they will continue to be useful and effective.

Here are five ways to evaluate your current enclosures for the world of the IoT.


1. Safety and Security

Enclosures may be placed in more vulnerable positions to accommodate the sensors and networking needed to make the IoT practical.

  • Assess both physical and cyber security for the enclosures.
  • Upgrade firmware regularly on all connected mechanisms.
  • Change passwords frequently.

Choose secure lock systems.


2. Protection

As enclosures move beyond the plant floor, exposure to potentially harmful ambient conditions becomes a concern.

  • Choose appropriate NEMA and UL ratings for each environment.
  • Assess ingress protection from such ambient contaminants as oil, dirt, salt air or product dust.
  • Avoid electromagnetic “noise” from motors, belts, and fans.

Choose the appropriate level of NEMA and UL protection for wall-mount and junction boxes.


3. Layout of operational controls

The IoT requires more equipment within the same enclosure so space efficiency and design become primary concerns for engineers.

  • Assess power management for increased density.
  • Audit cooling capacity to ensure additional devices do not impact thermal management.

Determine if panel modification is necessary to allow for additional cable management, via raceways, cabling trays, routing, clamping or busbars to reduce space requirements.


4. Scalability

Enclosure modularity can improve scalability and savings during expansion.

  • Assembly of additional enclosures should be easy to handle on-site.
  • Enclosures could be bayed side-to-side to accommodate custom configurations.
  • Doors should be reversible.

Interior racks need to be repositionable to house new equipment configurations.


5. Future-proof design

Assessing future needs during the design stage can enable operation infrastructure to handle future needs of the IoT.

  • Plan for tomorrow, not “just enough” for today.
  • Consider busbars instead of cabling for more power in less space.
  • Choose enclosures that are flexible for modification.
  • Assess designs to add modifications such as new knockouts, cable entry points, windows or HMI.

A comprehensive assessment of current and future IoT infrastructure can save long-term headaches and ensure success. For instance, the enclosure can play a vital role in the security of interconnected IoT devices. While there are concerns about software intrusion among IoT devices, there is a real threat in the
