The XE-11 Series is a ZigBee DI/DO module that integrates wired devices into ZigBee wireless networks to create automated responses and enhance security and convenience. Providing a digital input (DI) and a digital output (DO) that connect to wired devices, the XE-11 Series serves as a bridge of reliable and fast communication between a control system and wired devices over ZigBee networks. It is particularly useful for a control panel to obtain data from and activate remote field devices that are difficult or cost-prohibitive to reach.

The XE-11 Series turns the device connected to its DI into the trigger of events and the device connected to its DO into the responder of events. Its DI is a dry contact consisting of two metallic contacts. When the contacts are open, the device connected to the DI is in a normal condition. When the contacts are closed, the device connected to the DI reports either its status or an alarm. Devices commonly connected to the DI are smoke detectors, PIR motion sensors, door/window contacts, glass break detectors, panic/emergency buttons, etc.

The main benefits of the XE-11 Series include improving process efficiency and saving wiring efforts between the trigger and the control panel. Interoperable with any ZigBee devices adopting the ZigBee Pro HA 1.2 standard, the XE-11 Series can be flexibly incorporated into new or existing home automation systems. The two models of the XE-11 Series, the XE-11S and XE-11P, are designed for two different types of DI/DO architecture, where responses are triggered either by the control panel or by the device connected to the DI.
