About the Crestron CEN-IO-DIGIN-104
The four inputs share one 5-pin 3.5 mm detachable terminal block and are referenced to ground, accepting an input voltage range of 0 to 24 VDC. The module reports to the control system over the local network, so the state of connected equipment can be monitored remotely from a computer or tablet. Configuration is through Crestron Toolbox software or a web browser.
It is an IEEE 802.3at Type 1 (802.3af compatible) Class 0 PoE powered device consuming 1.8 W, so no local power supply or dedicated power wiring is required. Power can come from a PWE-4803RU injector in line with the LAN cable or a Crestron PoE switch such as the CEN-SW-POE-5. The 100 Mbps Ethernet port supports TLS 1.2, SSL and local authentication.
The black and blue IFE micro enclosure is 34 mm high, 128 mm wide and 73 mm deep, or 45 x 136 x 85 mm with its bracket, and weighs 180 g. Several CEN-IO modules can be stacked together, and the included bracket fixes the module to a flat surface or a 35 mm DIN rail, where it takes 8 module spaces. The Wi-Fi alternative is the CEN-IO-DIGIN-204.

Questions about the Crestron CEN-IO-DIGIN-104
What does the Crestron CEN-IO-DIGIN-104 do?
It adds four digital inputs to a Crestron control system over wired Ethernet. The inputs accept 0 to 24 VDC referenced to ground, and the module reports over the local network so connected equipment can be monitored remotely from a computer or tablet. It is powered by PoE.
How is the CEN-IO-DIGIN-104 powered?
It takes its power from the LAN cable as an IEEE 802.3at Type 1 (802.3af compatible) Class 0 PoE powered device and uses 1.8 W. A PWE-4803RU PoE injector or a Crestron PoE switch such as the CEN-SW-POE-5 can supply it, so no local power supply is needed.
What is the difference between the CEN-IO-DIGIN-104 and CEN-IO-DIGIN-204?
Both add four digital inputs in the same IFE micro enclosure. The CEN-IO-DIGIN-104 connects by wired Ethernet and is powered by PoE, while the CEN-IO-DIGIN-204 connects over Wi-Fi to a wireless access point and runs from an included 5 VDC power pack.
What voltage can the CEN-IO-DIGIN-104 inputs accept?
The four digital inputs are referenced to ground and have an input voltage range of 0 to 24 VDC. They connect through a single 5-pin 3.5 mm detachable terminal block, and their status is passed to the control system over the network.
How is the module mounted?
The IFE micro enclosure can stand freely, stack with other CEN-IO and IFE compliant devices, or attach to a flat surface or 35 mm DIN rail with the included bracket, taking 8 DIN module spaces (144 mm). It measures 34 x 128 x 73 mm and weighs 180 g.
How much is the Crestron CEN-IO-DIGIN-104?
Crestron asks its dealers to give the price of the CEN-IO-DIGIN-104 directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the CEN-IO-DIGIN-104?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CEN-IO-DIGIN-104 on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the CEN-IO-DIGIN-104 come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CEN-IO-DIGIN-104 develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the CEN-IO-DIGIN-104 in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the CEN-IO-DIGIN-104 without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
