1. APPLICATION
The Honeywell DBC1500 is a microprocessor-based
integrated burner controller for automatically fired
gas, oil or combination fuel industrial single burner
applications. The DBC1500 system consists of the
relay module and wiring sub base. The DBC1500
Standard Model provides the minimum
requirements to control an industrial burner system,
such as automatic burner sequencing, flame
supervision, system status indication, system or
self-diagnostics and troubleshooting.
The DBC1500 is programmed to provide a level of
safety, functional capability and features beyond
the capacity of conventional controls.
