Brand: K-Rain SKU: 2120
Product Overview
The K-Rain 2120 is a mechanical single-station controller designed to switch one approved 220-volt load on a repeatable irrigation schedule. It combines a 24-hour time dial with multiple start opportunities and a retained-pin 14-day scheduling system, giving pump-fed irrigation installations a straightforward way to run on selected days without relying on a multi-zone electronic controller.
This model accepts 220 VAC input and switches 220 VAC output for a compatible motor load rated up to 2 horsepower. Its double-pole, single-throw switching arrangement is intended for line-voltage equipment such as an approved irrigation pump or another compatible single-load application. The rain-tight enclosure and manual AUTO-OFF-ON control make the controller useful where simple, visible mechanical programming is preferred.
The 2120 is not a 24-volt irrigation station controller and does not directly power a standard 24 VAC valve solenoid. Confirm the pump, starter, wiring, supply voltage, motor horsepower, local electrical requirements, and any required overload protection before installation. Line-voltage wiring should be completed by a qualified professional following the current K-Rain instructions and applicable electrical codes.

Compatibility and Installation Notes
- Verify a 220 VAC supply and a compatible load of no more than 2 HP.
- This controller switches line voltage; it does not provide a 24 VAC station output.
- Use a properly sized pump starter or other required control equipment when the connected load or code requires it.
- Disconnect power before service and follow the current K-Rain wiring diagram.
- Have line-voltage installation performed by a qualified electrician or irrigation professional.
Frequently Asked Questions
Does the K-Rain 2120 operate a standard 24V irrigation valve?
No. The 2120 switches a 220 VAC line-voltage load and is not a conventional 24 VAC multi-zone valve controller.
What is the maximum motor rating?
K-Rain lists the 2120 for compatible motor loads up to 2 horsepower. Verify the motor nameplate and installation requirements before connecting it.
Can it run more than one irrigation zone?
It controls one electrical load. Multiple hydraulic zones may be possible only when that single load operates a properly designed indexing-valve system.
Why Buy This K-Rain 2120 from Big Frog Supply?
Big Frog Supply helps customers match exact irrigation-control part numbers instead of treating similar-looking 110V, 220V, and 24V models as interchangeable. That matters with the 2120 because its 220V input, 220V output, and 2 HP rating must match the pump and electrical design.
