Acromag EtherStax™ I/O Block 96-Channel Discrete I/O Acromag's new EtherStax I/O Blocks provide a ruggedized, high-density 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. • Bi-directional channels support any input/output mix in a single unit. • High-density stackable unit saves panel space. • Modbus TCP/IP or UDP/IP protocol; I/O functions as slave to host controller. • Peer-to-peer i2o communication. • Change-of-state or timed updates. • 10 Modbus TCP/IP sockets/sessions. Multiple masters can talk to an EtherStax unit at the same time. • Self-test checks I/O operation; test I/O channels from a web browser before wiring terminals to devices. • Selectable input "wetting" current eliminates pull-ups and improves dry contact interface. • Automatic change of state detection. • Internal or external port excitation. Selectable source on each 16-channel port simplifies wiring and adds flexibility. • Loop-back monitoring on all channels. • Watchdog timers and failsafe outputs. • Output open-load detection. • Thermal, current, voltage protection.
