Rain Bird ESPSM6 6-Station Expansion Module
Brand: Rain Bird | SKU: ESPSM6
Product Overview
Expand a compatible Rain Bird controller by six irrigation zones with ESPSM6. It is a useful choice for a larger landscape addition or for making the most of an available expansion bay in an ESP-Me, ESP-ME3 or ESP-SMTe controller.
Key Features
- Adds six stations through one expansion module.
- Fits ESP-Me, ESP-ME3 and ESP-SMTe controllers.
- Hot-swappable design allows installation without powering down the controller.
- Locking lever secures the module in its controller bay.
Common Uses
- Adding lawn, planting-bed or drip zones to an existing compatible system.
- Building toward a 22-station ESP-Me or ESP-ME3 configuration.
- Replacing a six-station module after confirming controller fit and the cause of a station fault.

Compatibility & Installation Notes
Read the controller model label before ordering: ESP-SMTe and ESP-SMT are different controller families. Check the available expansion bays and existing station count. ESPSM6 is an internal expansion component and requires a compatible controller.
On ESP-ME3, unlock the securing lever, position the module between the bay rails, push it fully into place and slide the lever to lock. Allow about 30 seconds for stations to become available for configuration. Follow your controller manual for zone wiring, run times and a station test.
When mixing module sizes in ESP-ME3, install six-station modules before three-station modules for ideal sequencing. Fixed station numbering can leave skipped positions where a bay is only partly populated; use the controller's displayed station numbers when wiring and programming.
Frequently Asked Questions
Does ESPSM6 fit the older ESP-Modular controller?
No. ESPSM6 is not compatible with older ESP-Modular (ESP-M) or ESP-SMT controllers. It fits ESP-Me, ESP-ME3 and ESP-SMTe; check the exact controller model before ordering.
How many zones does one ESPSM6 add?
One module adds six stations. For ESP-Me and ESP-ME3, a four-station base plus three six-station modules provides 22 stations. Existing modules and available slots determine how much expansion is possible.
Can ESPSM6 be installed with controller power on?
Yes, the module is hot-swappable. The ESP-ME3 manual permits installation or removal with or without AC power connected and advises allowing about 30 seconds before configuring the new stations.
How should I arrange mixed 3- and 6-station modules in ESP-ME3?
Install six-station modules before three-station modules for ideal station sequencing. ESP-ME3 uses fixed station numbering, so check the displayed station numbers and any skipped positions before wiring and programming.
Why Buy from Big Frog Supply?
Choose ESPSM6 when a compatible controller needs more than three additional zones or when you want six outputs from a single available bay. Three ESPSM6 modules can bring an ESP-Me or ESP-ME3 from its four-station base to 22 stations, making module choice important when planning a larger expansion. Confirm the model label first: the six-station option fits ESP-SMTe, but older ESP-SMT and ESP-Modular controllers require a different selection.
