RA890G1260 protective flame controller detailed introduction

Product overview

RA890G1260 is a burner controller produced by Honeywell, which is mainly used for the control of combustion systems. This controller has a number of key functions, including automatic ignition, flame monitoring and flameout protection, to ensure the safety and efficiency of the combustion process.

Main functions

Automatic ignition: can automatically start the ignition process to ensure the smooth start of the combustion process.

Flame monitoring: Monitor the flame status in real time. Once the flame is detected to be extinguished, protective measures will be taken immediately.

Flameout protection: When the flame goes out, the gas valve is automatically closed to prevent gas leakage and ensure safety.

Technical characteristics

Scope of application

RA890G1260 is suitable for use with a variety of industrial and commercial burners, including single and dual fuel burners, as well as UV flame detectors.

Structural features

Dimensions: 5in. high x 5in. wide x 43/4in. deep (including base) for easy installation and maintenance.

Frequency: Supports two frequencies of 50Hz and 60Hz, adapting to different power grid conditions.

Temperature range: -29¢XC to +41¢XC in 50Hz mode, -29¢XC to +46¢XC in 60Hz mode, adaptable to various ambient temperatures.

security features

Safe start check: Prevents starting when the flame detector circuit is faulty, improving safety.

Built-in ignition protection device: A built-in ignition protection device is included in the flame rod system to further ensure the safety of the ignition process.

Alarm relay switching mode: Use single pole double throw alarm device connection to provide reliable alarm signal.

Installation and maintenance

Installation precautions

The wiring of each terminal of the controller must be strictly insulated from the high-voltage ignition cable to avoid the risk of short circuit.

Do not mix live and neutral wires to ensure electrical safety.

When installing switches, fuses, grounding, etc., you must comply with the electrician's wiring rules to ensure stable operation of the system.

Maintenance recommendations

Regularly check for loose terminal blocks and plugs to ensure that electrical connections are firm and reliable.

Clean the surface of the flame detector to prevent dust and dirt from affecting the detection effect.

During use, if you encounter any abnormality, you should stop using it immediately and contact professionals for inspection and repair.

Application scenarios

RA890G1260 is widely used in industrial and commercial fields, especially in applications requiring efficient and safe combustion. Whether it is a large industrial boiler or a small commercial kitchen, RA890G1260 can provide reliable protection to ensure the safety and stability of the combustion process.
