RBI Boiler 15-0118 Power Relay

RBI Boiler 15-0118 Power Relay is an electrical switching component used to control high-voltage circuits through a low-voltage control signal in boilers and heating equipment. It is an interface between the control board and operational loads such as pumps, ignition systems, or safety circuits, ensuring switching during system operation. In HVAC systems it is installed inside control assemblies where it manages electrical load activation based on thermostat or secure inputs. It supports consistent sequencing, protects control circuitry from high current exposure and contributes stable operation during heating cycles.
