I/O Communication Adapters

A FLEX I/O adapter module interfaces FLEX I/O modules to an I/O scanner port across a communication network. The FLEX I/O adapter module contains a built-in power supply that converts 24V DC to 5V DC for the backplane to power the FLEX I/O modules. One adapter communicates with up to eight I/O modules, allowing connection to 256 digital input/output points, or 64 analog input points/32 analog output points, or a mix to meet your needs. Redundant media versions of standard modules have the letter R in the catalog number. Extreme environment versions have the letters XT in the last position of the catalog number, before the series designation. Conformal coated versions of have the letter K in this position.
