The 8883 is a custom flame supervisory and process control system for multiple burner applications. It is part of the new line of 888X series of North American Control Systems. The 8883 incorporates such features as color graphics display screens, touch screens, exten- sive use of personal computers (PC's), programmable logic controllers (PLC's), and the new Honeywell/North American RM7888 industrial burner controllers. These features bring a new look and an impressive increase in control capability.

The 8883 system consists of a single master control enclosure and individual burner boxes. The 8884 is functionally the same as the 8883, but the burner modules are housed in a single enclosure with the master control.

The PC or PLC provides overall process control, monitoring, and alarm reporting. The flexibility such a system allows it to be con- figured to meet many diverse process needs such as the imple- mentation of special control strategies like StepFire™. In addition, it can accommodate other process control loops, discrete logic control, plus analog and digital inputs and outputs beyond the combustion control operation.
