Honeywell has expanded its Spyder™ controller portfolio with the launch of Spyder with Relays, Sylk™ I/O and Zio® Lite Sylk-enabled wall modules, all of which aim to provide added flexibility and reduce installation. The Spyder controller now offers a Spyder with Relays model that eliminates the need to install separate switching relays when controlling roof-top or CVAHU equipment by adding relays to the Spyder hardware. The Spyder with Relays controller is available in LonWorks™ and BACnet™ protocols. It is also compatible with Honeywell’s new Sylk I/O module, which is a Sylk-enabled device that expands a single Spyder controller’s input and output (I/O) count by eight to 12 points modularly through a Sylk™ bus connection.
