Emerson Climate Technologies White-Rodgers 90-290Q Switching Relay 24V SPST 8A 50/60Hz
24V SPST switching relay handles resistive loads, single-phase motors, solenoids and two-speed motors at 8A via quick-connect terminals
- Controls resistive loads and single-phase motors
- Operates on 24 V coil voltage for low-voltage systems
- Switches up to 8 A at 120 V or 240 V AC
- Compatible with 50 Hz and 60 Hz power frequencies
- Quick-connect terminals simplify wiring installation
What this relay controls
This White-Rodgers 90-290Q is a 24 V SPST switching relay rated at 8 A for 120 V and 240 V resistive loads, single-phase motors, solenoids and two-speed motors. It operates at 50/60 Hz and uses quick-connect terminals for low-voltage wiring. The contact form is SPST on both the coil and load sides, and no low-voltage relay is included.
Check voltage and wiring before fitting
Verify that your control circuit supplies 24 V AC at 50/60 Hz and that the load does not exceed 8 A at 120 V or 240 V AC. Confirm the enclosure has space for quick-connect terminals and that the application matches resistive, motor or solenoid loads listed in the specifications. The relay is not rated for horsepower or locked-rotor current, so avoid circuits that demand those values.
Suits standard HVAC switching.
Installers needing a basic 24 V SPST relay for fan, valve or compressor control will find this unit appropriate. Buyers who require horsepower-rated contacts, locked-rotor current ratings or a built-in low-voltage relay should look at other models. The device is also restricted from sale in certain states, so confirm local availability before ordering.

Questions about this item
Does the relay come with any mounting hardware or wiring connectors, or do I need to buy those separately?
The relay uses four quick-connect terminals for electrical connections; no mounting hardware or additional connectors are included in the package.
Should I choose the 120 V AC or 240 V AC rating for my installation?
The same relay handles both voltages — it is rated 8 A at 120 V AC and 8 A at 240 V AC, so select the voltage that matches your supply.
What does the 8 A full-load current mean when the relay is controlling a motor or solenoid in my HVAC system?
It means the contacts can continuously carry up to 8 amps at either 120 V AC or 240 V AC for resistive loads, single-phase motors, solenoids or two-speed motors.
