These EtherStax I/O modules provide a rugged,
high-density, and high-speed solution to interface a large quantity of analog input signals to
SCADA and distributed I/O systems. Each unit
converts up to 64 single-ended analog voltage
signals from various sensors and instruments
for transmission to an Ethernet-based control
network. Typical applications include process
control, automated manufacturing, remote data
acquisition, test and measurement, embedded
computing, and supervisory monitoring systems.
