24-Bit Remote Discrete I/O Solution


Model RIO-24 is a ready-for-use Digital I/O solution with 24-bits in any combination of inputs or high-current outputs. The unit is housed in a steel enclosure and interfaces to a controlling computer through a wireless link, USB converter, or an RS-232 port via RS-485 converter. The core of the RIO-24 is our RDG-24 RS-485 Digital Input/Output REMOTE ACCES Pod. Typical applications include remote data acquisition and control of switches, relays and more. SOFTWARE SUPPORT A Windows based application is included that allows for establishing communication, quick setup and testing of I/O. The program displays all 24 inputs and outputs simultaneously, and allows for one-click direction configuration. Full source code is provided, as well as a number of other samples in a variety of languages to demonstrate techniques for developing custom applications for logic functions, etc. The RIO-24 can also be used as a stand-alone controller with the help of our Firmware Development Kit.
