Crestron CEN-IO-RY-204
Ethernet / Cresnet Relay + Versiport I/O Expansion Module
The Crestron CEN-IO-RY-204 is an I/O expansion module that provides four isolated relay outputs plus two Versiport I/O ports and connects to a Crestron control system over Ethernet or Cresnet. The relays switch low-voltage circuits for devices such as motorized screens, lifts, drapes, and contactors, giving a remotely located processor direct dry-contact control of physical loads.
The two Versiport ports each function as a digital input, analog input, or digital output for sensing contact closures and interfacing with other low-voltage equipment. Positioning the module near the controlled devices minimizes long wiring runs and cleanly extends a processor's switching and I/O capability, a practical choice for distributed automation throughout a building.
