Resideo by Honeywell R847A1085 Heavy Duty Switching Relay 120V DPST/SPST 2-Wire

The Resideo by Honeywell R847A1085 is a heavy duty switching relay designed for control of high-current 120V or 240V AC electrical loads such as cooling compressors, electric heating systems, and hydronic zone control applications. This relay features an integral 24V transformer that provides low voltage for the control circuit, eliminating the need for an external transformer.

Key Features:

• Flexible DPST (Double Pole Single Throw) or SPST (Single Pole Single Throw) switching configuration via internal leads
• 120V primary voltage, 50/60 Hz operation
• 24V AC coil voltage with integral transformer for 2-wire control
• Full load contact ratings: 22 amps @ 120V AC, 10 amps @ 240V AC
• Locked rotor contact ratings: 100 amps @ 120V AC, 50 amps @ 240V AC
• Self-cleaning relay contacts with wiping action
• Surface mount installation on vertical surface
• Dimensions: 5.25" H x 4.25" W x 2.75" D

This relay provides intermediate switching capability, allowing low-amperage thermostats and controllers to safely switch relatively high current loads. The contacts are engineered with a wiping action that keeps them self-cleaning during operation. UL Listed and CSA Certified for reliable performance in HVAC and industrial control applications.
