Product Description
The Honeywell RM7838C1020 is a semi-automatic burner control module in the 7800 Series designed for combustion control applications. It operates at 120 VAC and provides preignition, interrupted-pilot ignition sequencing, lockout interlocks, and a display for status indication. Timing functions include a 5-second early spark termination, selectable 4- or 10-second pilot establishing periods, and a 10-second or intermittent main flame establishing period; prepurge is determined by an ST7800A purge timer card.
- 120 VAC operation for semi-automatic programming control and interrupted-pilot burner applications
- Selectable timing: 4 or 10 s pilot establishing period; 10 s or intermittent main flame establishing period; 5 s early spark termination
- Preignition supported, prepurge determined by ST7800A purge timer card, lockout interlocks and included display for status
Product Highlights
7800 Series relay module providing interrupted-pilot sequencing, programmable timing options, and lockout diagnostics for industrial combustion systems.
