Crestron CEN-IO-RY-104 – Ethernet to 4-Port Relay Interface
Product Overview
The Crestron CEN-IO-RY-104 is an Ethernet-connected interface module providing 4 relay outputs for control of motorized screens, lifts, blinds, power contactors, and other relay-controlled devices at remote locations from a Crestron 4-Series control processor via IP. It eliminates long relay cable runs from the AV rack to remote device positions by placing relay outputs at the device location and controlling them over the building Ethernet network. Part of the Crestron CEN-IO control expansion family for distributing I/O to remote locations in commercial AV and building automation installations.
Key Features
- 4 Relay Outputs: Four independent dry contact relay outputs for motorized screens, lifts, power contactors, and other relay-controlled devices at remote equipment locations.
- Ethernet IP Control: Controlled by Crestron 4-Series processors via IP over the building Ethernet network — no long relay cable runs required from AV rack to device location.
- 4-Series Integration: Native Crestron IP integration — relay states commanded from the 4-Series SIMPL# program as if directly connected to the processor’s relay outputs.
