96-Channel Bi-Directional Discrete Ethernet I/O Modules

EtherStax I/O blocks provide a ruggedized, highdensity solution to interface a very large quantity of discrete I/O signals to your control system.

A stackable aluminum housing maintains a small footprint and stands up to harsh, industrial environments. Web-based configuration simplifies setup with any web browser.

  • Features
  • Ordering info
  • Self-test checks I/O operation: Test I/O channels from a web browser before wiring terminals to devices.
  • Watchdog timers and failsafe outputs: Communication fault sends output to a pre-defined state or holds the last value.
  • Peer-to-peer i2o communication: Inputs to one unit automatically update outputs on another over Ethernet link.
  • Internal or external port excitation: Selectable source on each 16-channel port simplifies wiring and adds flexibility for use with 5-28V DC logic.
  • Operating temperature: Open board, -40 to 75°C (-40 to +167°F); Closed board, -40 to 75°C (all outputs “off”); -40 to 70°C (all outputs “on” at rated Max.).
  • Output open-load detection: Output fault detection is selectable on individual channels.
  • Change-of-state or timed updates: Event-driven updates transmit data in less than 5mS between peers with i2o.
  • Selectable input “wetting” current: Internal current source eliminates pull-ups and improves dry contact interface.
  • 10 Modbus TCP/IP sockets/sessions: Multiple masters can talk to an EtherStax unit at the same time.
  • Loop-back monitoring on all channels: Inputs confirm output states for increased system reliability.
  • Automatic change of state detection: Inputs detect quick momentary changes of state that occur between polling.
  • Thermal, current, voltage protection: I/O is protected from excessive levels to reduce downtime.
