Brand: K-Rain SKU: 2510
Product Overview
The K-Rain 2510 is a rain-switch-ready mechanical single-station controller for scheduling one compatible 110-volt irrigation load. It is designed for applications that need dependable mechanical programming plus a convenient way to interrupt watering when a compatible rain sensor indicates that irrigation is unnecessary.
The controller accepts 110 VAC input and switches 110 VAC output for an approved motor load rated up to 2 horsepower. A 24-hour dial supports multiple start settings, while retained pins provide a repeating 14-day watering schedule. Built-in rain-switch terminals simplify sensor connection, and the controller-face override allows the rain-switch circuit to be managed without rewiring the installation.
The 2510 directly switches a line-voltage load; it is not a standard 24 VAC zone controller. A rain sensor is not included. Before ordering, verify that the connected pump or other equipment uses 110 VAC, falls within the controller's load rating, and is suitable for the double-pole, single-throw switching configuration. Installation requires proper grounding, overcurrent protection, enclosure placement, and compliance with electrical and irrigation codes. Line-voltage work should be performed by a qualified professional using the current K-Rain instructions.

Compatibility and Installation Notes
- Confirm 110 VAC supply voltage and a compatible load no greater than 2 HP.
- The rain switch and any required pump starter are sold separately.
- This model does not directly provide a conventional 24 VAC valve-station output.
- Use only compatible rain-switch wiring and follow the current K-Rain diagram.
- Disconnect power and use a qualified professional for line-voltage installation.
Frequently Asked Questions
Does the K-Rain 2510 include a rain sensor?
No. It is rain-switch ready, but the compatible sensor is purchased separately.
Is the output 24 volts?
No. The 2510 accepts and switches 110 VAC. It should not be confused with K-Rain transformer models that provide a 24 VAC output.
Can the rain switch be bypassed?
The controller includes a face-mounted rain-switch override. Follow the K-Rain instructions and use the override only when appropriate for the site.
Why Buy This K-Rain 2510 from Big Frog Supply?
Big Frog Supply identifies the 2510 by its exact 110V input/output, 2 HP load rating, and rain-switch-ready configuration. That helps prevent substitution with visually similar K-Rain timers that use different voltages, transformer outputs, or motor ratings.
