The XC-REL communicating relay module is designed for adding scheduling and control to any generic relay application. The relay module represents the latest in communications techniques incorporated into a rugged plastic case. The module contains four (4) independently controllable relays, each with NC, Common and NO connections. The RS-485 communications bus allows simple connection to the XC-SSA2/CLK network controller for complete access and control from any location. Each relay may be addressed separately for a possible total of over 1000+ relays on a network. Built-in non-volatile memory allows up to 256 schedules to be downloaded from the XCI Command Center software and stored in the relay module.

Note: you MUST use an XC-SSA2/CLK network controller with this device.
