Industrial Serial I/O Expander

The Serial XetaIO is a Class 1 Div 2 industrial serial I/O expander that is simple, reliable, and cost effective. The Serial XetaIO offers 8 programmable input and output channels for monitoring and controlling external sensors and devices.

The Serial XetaIO can be used with XetaWave products or any other serial product. One serial interface is available supporting RS-232, RS-422, and RS-485. When configured for RS-485, a second interface is provided making it easy to daisy chain together additional Serial I/O Expanders or other RS-485 products using standard Ethernet cables.

The Serial XetaIO shares a common Modbus map with all of the other XetaWave I/O products like the Ethernet XetaIO, Xeta9S serial I/O radio, XetaEdge edge computers, and all Ethernet radios.

  • Industrial Safe C1D2 certified and operational from -40°C to +85°C for hazardous industrial applications.

  • Programmable I/O Independently configure 4 I/O as analog inputs, analog outputs, or digital inputs and 4 I/O as digital inputs or outputs.

  • Resistors Built-in pull-up and pull-down resistors eliminates the need for external resistors. 

​​

  • Digital Input Multiple digital inputs for monitoring relays, switches, closure sensors, and alarms.

  • Digital Output Multiple digital outputs for controlling solenoids, latches, valves, pumps, lamps, or relays.

  • Analog Input Multiple 4-20 mA and 1-5 Vdc analog inputs for connecting sensors measuring temperature, humidity, flow, level, or pressure.

  • Analog Output Multiple 4-20 mA and 1-5 Vdc analog outputs for connecting to PLCs, RTUs, and flow computers.
