Crestron CEN-IO-DIGIN Network I/O Module, 4 Digital Inputs

The CEN-IO-DIGIN module puts four digital inputs wherever a contact closure needs reading, without running low-voltage cable back to a processor. All four sit on one 5-pin 3.5 mm detachable terminal block referenced to ground, accept 0 to 24 VDC, and switch at a logic threshold of 2.0 VDC low and 1.1 VDC high, which covers ordinary dry contacts, occupancy sensors, door contacts and third-party status outputs.

Choose the transport. The CEN-IO-DIGIN-104 is the wired model, taking data and power from one 100Base-TX RJ45 as an IEEE 802.3at Type 1 Class 0 powered device at 1.8 W, so a single Cat cable finishes the job. The CEN-IO-DIGIN-204 is the Wi-Fi model, an 802.11a/b/g/n client on 2.4 or 5 GHz with WPA2-PSK that remembers up to five access points and works to about 50 ft, powered by an included 5 VDC pack. Both models are the same IFE micro enclosure: a stackable black and blue plastic body that sits freestanding, screws to a flat surface, or clips onto 35 mm DIN EN 60715 rail using the included bracket, occupying eight DIN module spaces. Rack and pole mounting kits are sold separately. Setup is done from Crestron Toolbox or a web browser, and TLS 1.2, local authentication and SSL are supported on the control system and web connections. Front LEDs report power, control system connection and setup state.
