Crestron CEN-IO-DIGIN-204 – Wi-Fi Network I/O Extender with 4 Digital Inputs

Product Overview

The Crestron CEN-IO-DIGIN-204 is a compact Wi-Fi network I/O extender that adds four digital inputs to a Crestron control system over a standard wireless network. Designed for both commercial and residential AV control installations, it connects via Wi-Fi and integrates into Crestron's control ecosystem without requiring dedicated control wiring to the device location.

Product Description

The CEN-IO-DIGIN-204 expands the digital input capacity of any Crestron control system by communicating over Wi-Fi to the local network. The device is ideal for adding contact closure monitoring — such as door sensors, pushbuttons, or occupancy indicators — at locations where running dedicated Cresnet or Ethernet cable is impractical. It is provisioned and configured using Crestron Toolbox software and supports touch-settable ID for easy network enrollment. The extender ships with a mounting bracket that supports both flat-surface and DIN rail installation, and is powered by the included PW-0512WUL power pack. Its LED indicators provide clear status feedback for connection state and operational readiness.
