Resideo RA89A1116 Relay
The Resideo RA89A1116 is a professional-grade switching relay designed for contractors who need a reliable interface between a low-voltage controller and high-voltage HVACR equipment. This 120V unit features an integral transformer that provides the necessary 24VAC power for your control circuit, eliminating the need for an external power source. Built with a single pole single throw (SPST) configuration, it is ideal for switching circulator pumps, fans, and other line-voltage devices in hydronic and forced-air systems. The RA89A1116 relay is engineered for high-performance switching, featuring a maximum input of 5.0W and a secondary capacity capable of powering external loads up to 9VA. With its NEMA-standard enclosure and 2-wire control circuit design, this Honeywell Resideo relay ensures a clean installation and long-term durability in ambient temperatures up to 115°F. For troubleshooting, the unit includes a diagnostic LED and a push-to-test button to verify operation without cycling the thermostat.
Key Benefits for the Technician- Internal 24V Transformer: Simplifies field wiring by providing 12VA total secondary power, with 9VA available for external loads.
- Circuit Protection: Equipped with a replaceable 1A automotive-style fuse to protect the transformer secondary from shorts.
- Diagnostic Features: Integrated troubleshooting LED and manual test button allow for rapid system checkout and simplified commissioning.
- Durable Construction: Heavy-duty SPST contacts rated for 10.2A AFL at 120VAC, ensuring longevity under high inductive loads.
- Broad Compatibility: Replaces a wide range of legacy models and works seamlessly with mechanical and digital thermostats.
Can this relay replace the RA89A1074 model?
Yes, the RA89A1116 is functionally compatible with many legacy RA89 series units, though you should always verify the specific footprint and amperage requirements of your application before swapping.
What type of wire is approved for the screw terminals?
The captive wire clamp terminals are approved for copper wire only. Ensure all connections meet local electrical codes to prevent terminal overheating.
Is this unit suitable for outdoor installations?
No, the RA89A1116 is rated for indoor use within an ambient temperature range of -20°F to +115°F and a non-condensing humidity range of up to 90%.
