Horizontal Carousel Controller Upgrades
Modernize controls, boost safety, and integrate software, all without replacing your carousels.
Smarter Controls. Safer Operation.
Our Horizontal Carousel Controller (HCB) is a modern controller upgrade for legacy horizontal carousels. Replace aging electronics with a single wall-mounted enclosure that runs up to four carousels, adds VFD motion, safety PLC supervision, and operator-friendly HMIs. Connect to our inventory management solutions and pick-to-light systems for faster, more accurate fulfillment.

Inside the HCB Controls Package
The HCB upgrade combines every core component your carousels need into one compact, wall-mounted enclosure. From motion control and safety logic to intuitive HMIs and service tools, each element below works together to deliver smoother operation and easier maintenance.
Main Control Panel
Smoother starts/stops, reduced wear, and energy-efficient rotation.
Position/PLT Pick Light Tower
Shows shelf, quantity, and a grid for tote location to guide picking.
Safety Controller
Supervises E-Stops and sensors with clear status LEDs and fault messages.

OP3 Soft HMI
Push-button interface with plain-language alerts and carrier status.
Service Tools
Wireless Maintenance Keyboard (or budget Service button-pad) to move equipment safely during maintenance.
Upgrade vs. Replace
Compare the controls-only HCB retrofit with a full carousel replacement
Upgrade with HCB
- Keep your mechanics; replace controls

- Add HMI, light guidance, ERP links
- Safety PLC + VFD performance
Replace Entire System
- New hardware across the board
- Higher CapEx and more downtime
- Longer training and changeover
- Disruption to existing workflows.
