RIO-24
24-Bit Remote Discrete I/O Solution
Features
- Wireless (ranges up to 7 miles), USB, RS-485 or RS-232 connectivity
- Unit ships complete, power supply included
- Optional removable screw terminals for field wiring
- Software includes real-time display and log-to-disk feature
- I/O lines are configured as inputs or outputs by software command
- Outputs sink up to 350mA each, or switch between 0 and 5VDC
- Lines configured as outputs read-back at the connector to verify proper operation
- Pull-up resistors on inputs are provided to read dry-contact closures
- Compatible with industry standard solid state module racks like Opto-22

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.

VERSIONS
Model RIO-24-W includes a Wireless transceiver set. On the computer side, the Wireless module is powered by a wall adapter and plugs directly into an RS-232 port. It includes a wire antenna, and no software is needed, thus making the Wireless link transparent to the user. On the Remote side, the unit has a Wireless transceiver installed in the lid of the protective metal enclosure which is then wired into the I/O Pod. One AC/DC supply is included with this which plugs into 115VAC and powers all the electronics of the I/O and the Wireless module. The unit ships with a power cable and DB9 connector to plug into the DC output of the supply. Alternately, if no AC power is available at the remote site, a battery can be purchased instead of the AC/DC supply.The Wireless version is handy for systems where you need to add a remote alarm or pick up a contact closure at some distance from a PC, without running any wires. Different ranges are possible with different antennas, from a couple-hundred feet up to 7 miles with a clear line of site. A Spread-Spectrum un-licensed radio set is used with a frequency hopping feature for higher reliability.
Model RIO-24-U is packaged for connection to a USB port. This solution uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the RDG-24. Communications with the host computer are accomplished via our USB-485 converter to a cable wired up to the serial data screw terminals on the RDG-24.
Model RIO-24-S is packaged for connection to an RS-232 port via an RS-232 to RS-485 converter. This solution also uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the RDG-24.
Model RIO-24-E is packaged for connection to a Ethernet port. This solution uses the PC power supply through a spare Molex connector, to our PC-POWER-OUT cable which installs with a card mounting bracket that has a DB9F connector on it. Mating to the DB9F is a fused power cable which connects +12V to the power input of the RDG-24. Communications with the host computer are accomplished via our ethernet to 485 module wired directly to the serial data screw terminals on the RDG-24.
