# Description

The smartCUE-relay is a lightweight controller with three bi-directional RS-232/485 control ports, six versatile ports, and six low-voltage relays. Fully compatible with CUE touch panels, this controller can work as a standalone device. Depending on the application each versatile port can be used as an input or output.

The controller keeps date and time with its onboard real-time clock (RTC), thus allowing for a wide variety of distributed intelligence scheduling applications. A single cable Ethernet connection provides system communication with the rest of the Cue System. 

The controller is equipped with Power over Ethernet (PoE) technology enabling an Ethernet network cable to deliver both data and power. The controller installs easily on a table or into a 19” rack.

This controller comes with a web server and allows set up through a standard web browser. Unit programming is based on CUE’s standard programming tool Cue Visual Composer.
