Rain Bird ESPLXDSM75 75-Station ESP-LXD Module

Rain Bird ESPLXDSM75 75-Station ESP-LXD Module

Brand: Rain Bird | SKU: ESPLXDSM75

Product Overview

Increase the addressable station capacity of a Rain Bird ESP-LXD decoder controller with ESPLXDSM75. The controller starts with 50 stations; each SM75 adds another 75, giving 125 stations with one module or 200 with two. Choose this module when the ESP-LXD needs more programmed station capacity and has an expansion slot available.

Key Features

• Adds 75 stations to an ESP-LXD controller.
• One module expands the base 50-station controller to 125 stations.
• Two modules expand capacity to the ESP-LXD maximum of 200 stations.
• Hot-swappable design allows installation without powering down the controller.

Common Uses

• Expanding an ESP-LXD installation beyond 50 programmed stations.
• Adding the second expansion module when capacity needs exceed 125 stations.

Technical Specifications

• Model: ESPLXDSM75 / ESP-LXD-SM75; factory part: F43150.
• Compatible controller: Rain Bird ESP-LXD series only.
• Station capacity added per module: 75.
• ESP-LXD base capacity: 50 stations.
• With one SM75: 125 stations total.
• With two SM75 modules: 200 stations total.
• Installation: hot-swappable; controller automatically recognizes the module.
• Expansion module only; controller, field decoders and valves are separate.

Compatibility & Installation Notes

Confirm that the controller is ESP-LXD and check how many SM75 modules are already installed. This module is not specified for ESP-LXME or ESP-LXIVM controllers.

Use the ESP-LXD station-expansion socket. Orient the module connector to the backplane socket and press firmly until it clicks into place; avoid bending the pins. Follow the controller manual when accessing the cabinet.

The controller recognizes the installed module automatically. Check the station setup after installation and program the added stations and decoder assignments as required.

Added station capacity does not supply field decoders or valves, and it does not by itself increase the controller’s simultaneous-operation limits. Plan the two-wire system and hydraulic demand separately.

Frequently Asked Questions

How many stations does one ESPLXDSM75 add?

One module adds 75 stations, increasing an ESP-LXD from its base 50 stations to 125 stations.

Can I install two modules?

Yes. Two SM75 modules bring the ESP-LXD to its maximum 200-station capacity.

Must I power down the controller to install it?

Rain Bird describes the module as hot-swappable, so it can be installed without powering down the ESP-LXD. Follow the controller’s installation instructions.

Does it include the field decoders?

No. It expands controller station capacity; the two-wire field decoders and valves are selected separately.

Why Buy from Big Frog Supply?

Choose ESPLXDSM75 when an ESP-LXD needs a 75-station capacity increase. The 50-to-125-to-200 progression makes it possible to select one or two modules from the required station count, and the hot-swappable design supports an in-place controller expansion. Check available sockets and existing capacity before ordering; this module expands the ESP-LXD rather than replacing its field decoders.
