DIGITAL BURNER CONTROLLER 

DBC2000 SERIES 

 

 

 

1. APPLICATION 

The Honeywell DBC2000 is a microprocessor-based 

integrated burner controller for automatically fired 

gas, oil or combination fuel industrial single burner 

power burner applications. The DBC2000 system 

consists of the relay module and wiring subbase. 

The DBC2000 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 DBC2000 Enhanced Model 

includes an integrated Valve Proofing System, 

whilst the Ultimate model includes bus 

communication on top of this. 

The DBC2000 is programmed to provide a level of 

safety, functional capability and features beyond 

the capacity of conventional controls. 

2. FEATURES 

 

Employs a plug-in mounting method 

 

Uses a microprocessor to improve performance 

 

Status and fault indication by indicator LEDs 

 

A 4-wire firing rate switching circuit controls an air 

damper motor or other auxiliary equipment during 

start-up of the burner. 

 

Safe start check before and during pre-purge 

 

Dual flame amplifier for UV, IR or flame rod sensor 

 

Automatic recycle once per 24h of uninterrupted 

heat demand.   

 

Frontal jack plug (Ø 3.5mm) to read the flame 

signal with a microampere meter. 

 

An electrical sub base lock (reset and safety limit 

terminals are swapped) to avoid that a Standard 

model is used systems wired for an Enhanced or 

Ultimate model. The DBC2000 cannot start then. 

 

Safety shutdown occurs on 

malfunction of the burner controller 

failure to ignite the pilot burner or main burner 

loss of flame during run period 

opening of air flow switch during pre-purge, start-

up, run and post-purge period 

flame signal detection during standby or pre-

purge period 

 

Integrated Valve Proofing System (Enhanced and 

Ultimate models only) 

 

Remote bus communication (Ultimate model only)
