Honeywell RM7824A1006 7800 Series Relay

Configured for sequence execution, flame monitoring, and valve control in automated burner systems, the Honeywell RM7824A1006 ( RM7824A Relay Module) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel Isolation

The module manages automatically sequence-controlled burner operations using internal microprocessor logic powered by a 24 VDC input. Onboard timing circuitry executes defined intermittent pilot ignition sequences with selectable 4-second or 10-second pilot flame establishing periods (PFEP). Integrated safety isolation circuits continuously evaluate input status from the flame amplifier and limit switches, enforcing a fail-safe lockout state upon flame loss or signal failure to prevent unburned fuel accumulation.

Frequently Asked Questions

Q: What power supply input limits must be maintained for the RM7824A1006 module?

A: The module requires a regulated 24 VDC power supply. Operating outside nominal DC voltage tolerances can cause internal logic resets or prevent safety relay energization.

Q: Can the RM7824A1006 relay module be unplugged from its wiring subbase under power?

A: No, supply power must be disconnected from the subbase before inserting or removing the relay module to prevent electrical arcing on pin terminals and logic disruption.

Field Installation Guidelines

1. Disconnect all electrical power sources supplying the 7800 Series subbase before installing or servicing the RM7824A1006 module.
2. Ensure the wiring subbase is securely earth-grounded to the burner enclosure panel in accordance with applicable electrical codes.
3. Align the module terminal pins with the subbase receptacle and push firmly until the mounting screws engage completely.
4. Route low-voltage flame signal leads in dedicated conduit, isolated from high-voltage ignition transformer wiring to prevent cross-talk noise.
