Flexible Analog Monitoring

  • X-22S

 The X-22S™ eight-analog-input expansion module is used with an X-400™ or X-600M™ controller. It has eight precision analog inputs that can be configured for various voltage ranges and 4-20mA sensors.

  • 8 Analog Inputs
  • Expansion Module for the X-400™ or X-600M™

The X-22S™ is ideal for measuring precision analog voltages. This includes monitoring temperature, electrical current, pressure, and fluid levels. It is a great fit for environmental monitoring, wastewater, and greenhouse applications.

The X-22S™ employs a 16-bit SAR A/D converter and can make both single or differential input measurements. A 5.0V reference output can be used to power potentiometers or other resistance sensing sensors. One or more X-22S™ expansion modules can be connected with a ribbon cable that provides both power and communication.
