CDVI AIOM – ATRIUM Input/Output Expander Module
The AIOM by CDVI is an input/output expander module designed for use with the ATRIUM online access control system. It provides additional connection capacity, supporting up to 20 inputs using zone doubling technology and 10 outputs, making it ideal for installations that require additional monitoring and control points.
The AIOM features a built-in power supply and battery charger, along with an RS485 communication bus that is automatically detected by the ATRIUM controller. This eliminates the need for jumpers or DIP switch configuration, helping simplify installation and reduce the risk of setup errors.
Once connected to the communication bus, the AIOM is automatically detected and synchronised with the controller. It can be installed anywhere within a communication range of up to 1,220 metres (4,000 feet), providing flexibility for larger installations.
