XANTECH CC12 Remote Relay Module
The CC12 is an IR remote controlled double pole/double throw relay module. It provides dry contact closures to satisfy a variety of uses, such as activation of screen drops, and projector lifts. The switching is accomplished by way of infrared commands originating  from a Xantech RC68+ programmer (or RC68 programmer). It can also be switched by a DC voltage applied between the CI (control input) and GND terminals. The RC68+ commands are "taught" to learning devices and passed to the IR IN, and GND input terminals of the CC12 signal input terminals via Xantech IR receivers, keypads and connecting blocks.
