K-Rain 2520 2 HP 220V Irrigation Timer with Rain Switch
Brand: K-Rain | SKU: 2520
Product Overview
The K-Rain 2520 is a mechanical single-load controller for one compatible 220V irrigation pump. It combines a repeating watering schedule with terminals for an optional 24V rain switch, allowing pump-fed irrigation to pause after sufficient rainfall without changing the programmed schedule.
The main input and switched output are both 220 VAC; the 24V reference applies only to the compatible rain-switch circuit. Before ordering, confirm the supply voltage, motor voltage and horsepower, switching requirements, sensor compatibility, wiring method, and required electrical protection. This is not a conventional 24 VAC multi-zone valve controller.

Compatibility & Installation Notes
Confirm the exact motor nameplate, supply voltage, load, wiring method, and local code requirements. The compatible rain switch is not included, and the main output remains 220 VAC. Use required disconnects, grounding, overload devices, and circuit protection. Line-voltage work should be performed by a qualified professional following current K-Rain instructions.
Frequently Asked Questions
Does the K-Rain 2520 output 24V to the pump?
No. It switches a 220 VAC load; 24V refers to the compatible rain-switch circuit.
Is a rain sensor included?
No. The controller is sensor ready, but the compatible sensor is sold separately.
Can it operate standard 24 VAC irrigation valves directly?
No. It is a single-load line-voltage controller.
What size motor can it control?
K-Rain rates it for an approved 220V motor load up to 2 HP.
Why Buy the K-Rain 2520 Irrigation Timer?
