ESP-LXD Controller

Two-wire controller

The result of 40 years of expertise and thousands of installed units, the ESP-LXD is a modern, reliable, two-wire decoder controller. With a large display, simple-to-use ‘hand’ ‘off’ ‘auto’ dial, English/Spanish language support, and extra simple programming, the ESP-LXD dramatically cuts installation and troubleshooting time for even up to the most extensive operations.
