The EtherStax I/O from Acromag provides a stackable, ruggedised high density solution to interface a very large number of digital I/O signals to your control system. Automatic change-of-state detection of fast momentary changes can be transmitted elsewhere using the i2o feature.
The watchdog timer sets outputs to a predefined state and trips an alarm if communications fail. The Ethernet interface supports Modbus/ TCP/ UDP/IP for reliable host data transfers or peer-to-peer communication. Web-based configuration simplifies setup with any web browser.
