The Allen-Bradley 1794-IE8XT FLEX I/O module is an analog I/O module that can connect to an adapter and a terminal base to make a complete FLEX system that can handle all the same applications that rack-based I/O can. In this system, the Allen-Bradley 1794-IE8XT FLEX I/O module has the bus interface and the circuitry that is necessary to perform all the special functions required by an application, the terminal base comes with a terminal strip that terminates the wiring in 2-wire devices and in 3-wire devices, and the adapter or power supply can support the internal logic in up to 8 FLEX I/O module.

The Allen-Bradley 1794-IE8XT FLEX I/O module does not contain any outputs, but it has 12 inputs that are all single-ended and non-isolated. Its nominal DC voltage rating is 24 Volts DC and its adjustable voltage ranges are 0 to 10 Volts DC and -/+ 10 Volts DC. Its current can also be adjusted between 0 and 20 mA or between 4 and 20 mA. The Allen-Bradley 1794-IE8XT FLEX I/O module has a 3-position keyswitch on the front panel that can be used to install it. The users can rotate the keyswitch clockwise on the terminal base unit until the keyswitch is in the correct position for the Allen-Bradley 1794-IE8XT FLEX I/O module to be mounted and secured in place. Once the module has been mounted and the terminal base has been wired, the users should not rotate the keyswitch again. Doing so could disconnect the I/O module and cause damage to the module and the terminal base.
