Rain Bird PSR110IC 110V Universal Pump Start Relay
Brand: Rain Bird | SKU: PSR110IC
Product Overview
Connect a compatible 110-volt single-phase pump to an irrigation controller’s pump-start command with Rain Bird PSR110IC. It adds an ice-cube relay to the pump-start arrangement for supported two-wire controller/decoder applications. Select it for the 110-volt line configuration and the model-specific motor range of 3/4 through 2 HP.
Key Features
- 110-volt single-phase pump line arrangement.
- 24 VAC control connection.
- Additional ice-cube relay for supported two-wire control applications.
- NEMA 3R steel enclosure with grounding provision.
Common Uses
- Starting a correctly matched irrigation pump from a compatible control system.
- Replacing a matching Universal PSR after checking line voltage and controller or decoder output.

Compatibility & Installation Notes
Choose the 110-volt model for a matching motor supply and check the motor nameplate. Do not use a different voltage column from the shared relay-component table as permission to change the model’s specified line configuration.
Confirm that the controller or decoder provides the required 24 VAC control arrangement. The ice-cube relay does not make the unit compatible with every decoder or a different control-voltage type.
Have a qualified installer follow the supplied relay and motor wiring diagrams with all power disconnected. Keep the factory internal wiring intact and complete the specified grounding connection.
Provide appropriate motor thermal-overload and circuit protection. Starting the pump on command is different from protecting it against every overload or operating fault.
The published Universal PSR installation guide applies to units built from January 2002 onward. Use the unit’s supplied diagram and obtain manufacturer guidance for an older installation.
Frequently Asked Questions
Is 24 VAC the pump supply voltage?
No. It is the controller/interface control connection. PSR110IC is selected for a 110-volt motor line arrangement.
What motor size is listed for PSR110IC?
The manufacturer’s model table lists 3/4 through 2 HP for PSR110IC, subject to the specified supply and required motor thermal protection.
Why does it have an ice-cube relay?
Rain Bird includes the additional relay for supported two-wire controller/decoder applications. Verify the exact controller output before installation.
Does the relay replace motor overload protection?
No. Provide the motor and circuit protection required for the actual installation; the pump-start function alone does not provide complete pump protection.
Why Buy from Big Frog Supply?
Choose PSR110IC for a compatible 110-volt pump installation that needs the Universal PSR ice-cube relay arrangement. Its 24 VAC control input and model-specific 2 HP maximum distinguish it from the 220-volt PSR220IC and the standard dual-voltage PSR110220. Check the motor nameplate and controller or decoder output together so the relay matches both sides of the installation.
