The Fiber Optic Expansion I/O System (FOX) is an innovative bus extension that greatly expands the number of standard SmartStack™ I/O that can be used with the Operator Control Station (OCS), as well as adding a variety of architecture options and is available in both metal and plastic versions to suit your product requirements.
SmartStack I/O are rugged, stackable I/O modules for the OCS. By stacking SmartStack modules on bases connected to the OCS by plastic fiber, you can add up to 20 SmartStack I/O modules. And the FOX Bases can be distributed and DIN-rail mounted to reduce installation cost. SmartStack FOX is not a remote I/O system, but a high speed (8MHz) bus extension. It is based on inexpensive plastic fiber technology that has been used in the consumer electronics industry for years. Plastic fiber is much more rugged than glass fiber, supporting bend radius as small as 25mm (one inch).
Increases I/O Capacity :
Each FOX Base can support up to 4 SmartStack modules. You can have a maximum of 5 FOX Bases and they can support up to 20 I/O modules in total plus any mounted directly to the OCS. For OCS units that do not have integrated Fiber Optic Connection (OCS1XX/2XX) a FOX100 SmartStack Expansion Module can be used. This then is a simple and cost effective way to dramatically increase I/O capacity to a maximum of 23 units.
More Installation Options :
SmartStack FOX supports a variety of architectures, offering greater flexibility in I/O layout. These include Star, Daisy-chain, or Combination. Each SmartStack FOX cable segment can be up to 10m in length, with no Base/Hub located more than three segments (3x10m) from the OCS. Standard SmartStack FOX cables are offered in 0.5m, 1.0m, 2.0m, 5.0m, and 10m lengths.
