Information About RM7838C1020
The RM7838C1020 is a Honeywell 7800 Series semi-automatic programmer with four-wire modulation and a 5-second main flame establishing period. It uses a selectable 4- or 10-second pilot flame establishing period and requires an ST7800C purge timer for the purge sequence. The module supports flame supervision, preignition, lockout interlocks, high/low-fire control, and diagnostic functions. Honeywell identifies the RM7838C1020 as SIL 3 capable when used within a properly designed safety instrumented system.
Key Features:
- Burner Control: Provides microprocessor-based sequencing and supervision for industrial combustion systems.
- Semi-Automatic Operation: Designed for semi-automatic burner programming and control.
- Four-Wire Modulation: Supports four-wire modulating burner control with high- and low-fire functions.
- Flame Supervision: Works with compatible Honeywell flame amplifiers for continuous flame monitoring.
- Selectable Timing: Provides selectable 4- or 10-second pilot flame establishing periods.
- 5-Second MFEP: Provides a 5-second main flame establishing period for this C1020 model.
- Diagnostic Functions: Provides system status indication, self-diagnostics, and troubleshooting capabilities.
- Safety Functions: Includes preignition and lockout interlocks for burner safety control.
The RM7838C1020 delivers the control and monitoring functions required for industrial burner management, flame supervision, and combustion-system applications.
