Description
Offers Flexible Analog Monitoring
The ControlByWeb X-22S™ is the ideal solution for measuring precision analog voltages and 4-20mA signals. This includes monitoring such things as temperature, electrical currents, pressure, fluid levels etc. It is an excellent fit for environmental monitoring, wastewater, and greenhouse applications.
The CBW 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 via an X-400 or X-600M Controller Module.
