2 Sec Initiate Relay Module

Honeywell EC/RM7850A Relay Module are microprocessor based integrated burner control for automatically fired gas, oil or full modulation power burner applications.

Overview

Honeywell EC/RM7850A Relay Module are microprocessor based integrated burner control for automatically fired gas, oil or full modulation power burner applications. The EC/RM7850A system consists of the relay module, wiring subbase, amplifier and purge card. Options include the keyboard display module (KDM), personal computer interface, data ControlBus™ Module and combustion system manager® Software. The KDM can be mounted on the relay module or on the face of a panel door. The EC/RM7850A are programmed to provide a level of safety, functional capability and features beyond the capacity of conventional controls. The basic functions of the EC/RM7850A includes automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics, and troubleshooting.
