EtherStax line of rugged, high-density Ethernet I/O blocks for distributed I/O and SCADA applications now includes channel-isolated discrete I/O. Channel-to-channel isolation adds further protection from transients and noise. ES2116, ES2117, and ES2118 models process 32 discrete inputs and 16 outputs with a Modbus TCP/UDP/IP interface to a host controller.
i2o technology enables peer-to-peer communication between I/O units. Dual network ports support 10/100Base-TX copper and 100Base-FX fiber-optic connections with a redundant communication path for critical applications. Dual DC power terminals enable use of redundant power sources. An embedded web page provides configuration menus accessible with any web browser to eliminate programming. Multiple units can stack in an 8 x 7″ footprint. An open board version is available for custom mounting.
Three models, each with 32 input channels and 16 output channels, support a variety of I/O ranges. The ES2116 has a 97 to 132 Vac input range, and the two other units range from 20 to 135 Vdc, depending on the model. All models provide 5 A at 250 Vac or 30 Vdc SPST outputs.
