A system and method for injecting catalyst into a fluid catalyst cracking (FCC) unit is provided. In one embodiment, a system for injecting catalyst into a FCC unit includes a catalyst injection apparatus coupled to a controller. The controller is housed in an enclosure suitable for hazardous service and has a communication port for communicating information derived information regarding activity of the catalyst injection apparatus to a device remote from the enclosure while the enclosure is sealed. In another embodiment, a method for injecting catalyst into a FCC unit includes the steps of dispensing catalyst from an injection system into a FCC unit, storing a record of system activity in a memory device disposed in an enclosure suitable of hazardous duty, and accessing the stored record without exposing an interior of the enclosure to an environment surrounding the enclosure.
