Description
The Honeywell RM7890B-1048 Control is an On/Off primary control designed for atmospheric burners, featuring a shutter drive output, valve proving functionality, and blinking LED fault annunciation. This microprocessor-based burner control is suitable for industrial semi-automatically fired gas, oil, coal, or combination fuel single burner applications, providing advanced safety and functionality beyond conventional controls. It includes intermittent pilot operation and requires components such as the Q7800A or B Universal Wiring Subbases and various flame signal amplifiers (R7847, R7848, R7849, R7851, R7852, R7861, or R7886). This control ensures enhanced reliability and performance in demanding industrial environments.
