What is the i2o feature on many Ethernet products?
Acromag's i2o® technology enables direct input-to-output communication without a controller in between.
Ethernet i2o technology is the easiest way to link your inputs to your outputs without a PLC, PC or master CPU. Many BusWorks 900EN and EtherStax ES2000 I/O modules now have the ability to operate like a long-distance transmitter. Convert your sensor inputs at Point A to process control signals at Point B. Or, monitor a discrete device at one site by reproducing the discrete level with a relay output at another location. That is an input channel on one unit writes the data value to an output channel on a different unit.
