The X-22s expansion module is used with an X-400 or X-600M controller. The X-22s has eight precision analog inputs that can be configured for various voltage ranges and 4-20mA sensors. 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. The X-22s is ideal for measuring precision analog voltages in industrial environments.

One or more X-22s expansion modules can be connected to an X-400 controller with a ribbon cable. The ribbon cable provides both power and communications to the expansion modules.

Other expansion modules with different I/O combinations are also available.
