The RIO-28 Programmable I/O Module provides an easy way to read and
control analog and digital signals. In many instances, it can
completely eliminate the need for an RTU at remote points.
- Transient & over-voltage protection on all I/O
- Can operate as standalone or in a mirror mode
- 32-bit counter on each input is saved, even through power outages
- Made in the USA
In addition to standalone and mirror modes, the RIO-28 Programmable
I/O Module can execute code that you create with our Integrated
Development Environment (IDE). These programs can automate many
tasks that might be done manually or with a PC or RTU.
User programs can also give your I/O module the ability to
communicate with other devices. Connect the RIO to a cellular
modem, for example, and have your program send an SMS to indicate
an error condition!
