FLEX I/O Modules

FLEX™ I/O is a cost-effective, flexible, modular I/O system for distributed applications, offering all the functions of larger rack-based I/O without the space requirements. This, along with outstanding reliability, is why we have sold over 5 million modules.

Conformal coated versions of standard modules have the letter K in the last position of the catalog number, before the series designation. Available terminal bases include: 1794-TB3K, -TB3GK, and -TBNK.

Terminal Bases

Each FLEX I/O module requires a terminal base unit that snaps onto the DIN rail to the right of the I/O adapter. The terminal bases provide terminal connection points for I/O wiring and plug together to form the backplane. They are available with screw or spring terminations.
