## Overview

The XTB-523 is a high-power X10 powerline control interface designed to replace the discontinued TW523/PSC05. It outputs a robust 20Vpp signal at 120KHz, supports two-way extended code communication including dim commands, and features error checking with collision cancellation. An optional repeater function boosts X10 command range, revitalizing existing home automation networks without costly upgrades. Plug-and-play with standard 120V AC outlets, it’s the ultimate solution for professional-grade, reliable X10 control.

## Description

The XTB-523 is a high-power X10 powerline control interface. Many third-party controllers use the X10 TW523 / PSC05 as their powerline interface. That product is no longer available, and the XTB-523 was developed to fill the gap. It goes way beyond the basic functionally of the simple TW523. Its transmitter produces a much stronger signal than other X10 transmitters. Depending on line characteristics, the XTB-523 can output 20Vpp at 120KHz onto the AC line. While the TW523 could transmit extended codes, the XTB-523 can also receive them. The XTB-523 will also receive every dim command in a sequence. The XTB-523 error checks all incoming data, and can cancel its transmission when a collision is detected. And the XTB-523 also includes an optional repeater capability to boost X10 commands sent by other transmitters throughout the system. That includes the ability to repeat a series of sequential dims to avoid their being recognized by some dimmers as micro-dim commands. The XTB-523 can be plugged into any standard 120V 60Hz AC receptacle. The closer that receptacle is to the distribution panel, the stronger signals will be throughout the home. That may be a factor when the repeater capability is enabled. Since the XTB-523 only drives the phase it is plugged into, a good tuned-circuit passive coupler like the XPCP should be installed near the electrical panel when X10 devices are on both phases. An active coupler/repeater like the XPCR will not do that. The XTB-523 emulates the X10 TW523 / PSC05 in the default configuration. Optional capabilities, such as the repeater function, are selected through a sequence of X10 commands. More information is available here: http://jvde.us//xtb/XTB-523_description.htm

Review: I just installed this on my home automation system (HAI/Leviton) ... - I just installed this on my home automation system (HAI/Leviton) and it is working well. It gives a more reliable signal vs my old X10 TW523 which apparently stopped working after 8 years.
Review: Brings X10 Network back to life - As advertised. My X10 devices slowly became unreliable, then disappeared. This product brought everything back, including devices I forgot were out there. When the devices started to fail, I considered upgrading to Z-wave or other technologies. The cost to do that is quite high. Investing in this device made all of that unnecessary as the installed X10 devices work fine when the delivered signal is strong, which is what this product produces.

### ⭐⭐⭐⭐⭐ I just installed this on my home automation system (HAI/Leviton) ...
*by J***K on February 28, 2018*

I just installed this on my home automation system (HAI/Leviton) and it is working well. It gives a more reliable signal vs my old X10 TW523 which apparently stopped working after 8 years.

### ⭐⭐⭐⭐⭐ Brings X10 Network back to life
*by B***I on April 29, 2024*

As advertised. My X10 devices slowly became unreliable, then disappeared. This product brought everything back, including devices I forgot were out there. When the devices started to fail, I considered upgrading to Z-wave or other technologies. The cost to do that is quite high. Investing in this device made all of that unnecessary as the installed X10 devices work fine when the delivered signal is strong, which is what this product produces.

### ⭐⭐⭐⭐⭐ X10 devices working again
*by V***N on July 7, 2018*

As I moved from X10 to UPB technology throughout the years, I noticed more X10 switches were failing to respond to HAI because of noise. Changed the old interface from HAI to the XTB-523 and now all of my X10 devices are working again. Excellent product!
