Bailey Infi 90 Modular Power System

  • Provides Power to Various Process Control Modules
  • Scalable Power for Logic and I/O Functions
  • Shared Output Between all Modules


The Bailey Infi 90 Modular Power System provides +5, +15, -15, and +24 VDC to power process control modules and field termination devices. The system consists of the power entry panel; fan assembly; power supply modules and their mounting unit; bus bars; and associated wiring. The power modules provide scalable power for logic and I/O functions through N+1 redundancy. In this type of redundancy, power modules equally share output. If any power module fails, the remaining power modules adjust their outputs to meet the total system load. Therefore, redundancy can be provided by one extra module beyond the minimum number required to power the system.

Product Family: Infi 90, IEPEP01, IEPEP03, IEFAN0, IEPAS01, IEPAF01, IEMMU01

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
