Key Features and Functionality
The RM7895 A 1014 module is the brain of a burner management system,offering critical features that ensure a burner operates safely and efficiently.Its microprocessor constantly monitors the burner’s sequence,from the initial pre-purge to post-purge shutdown.
Integrated Safety Timings:The module has built-in,non-adjustable timings for critical phases such as pre-purge(clearing unburned fuel),trial for ignition(the period for establishing a stable flame),and inter-purge(the time between burner cycles).These fixed timings simplify setup and guarantee a consistent safety protocol.
Flame Supervision:The RM7895 A 1014 works with various Honeywell flame amplifiers and detectors,including flame rectification rods,ultraviolet(UV)sensors,and infrared(IR)sensors.It continuously monitors the flame signal.If the flame is lost during operation,the module will initiate a safe shutdown and lockout,preventing unburned fuel from accumulating.
Diagnostics:The module provides diagnostic LEDs that offer visual feedback on the burner’s operational status.This simplifies troubleshooting for technicians,who can quickly identify the cause of a fault—like a failed ignition or loss of flame signal—without needing complex diagnostic tools.
Application Versatility:The RM7895 A 1014 is designed for on/off and modulating burners with an intermittent pilot.This makes it a versatile solution for a range of commercial and light industrial applications,including boilers,air heaters,and process ovens.
Common Applications
The HONEYWELL RM7895 A 1014 module is widely used in commercial and industrial settings where burner safety is critical.
Commercial and Industrial Boilers:It’s commonly found in steam and hot water boilers for process heating or building climate control.The module ensures the boiler’s burner ignites and operates safely,protecting both equipment and personnel.
Process Air Heaters:In manufacturing and food processing,air heaters are used for drying,curing,or baking.The module’s precise sequencing and flame supervision are essential for maintaining stable temperatures and preventing explosions.
Incinerators:For waste management or emissions control,the RM7895 A 1014 is used to control the burner in incinerators,ensuring a reliable and safe combustion process.
