COMBINATION I/O MODULES IN A MODULAR AUTOMATION CONTROLLER

Abstract

The invention describes combination I/O modules for automation. Various combinations of inputs and output with different electrical interfaces are offered providing greater flexibility in controller hardware selection.

Description

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 shows a block diagram of an I/O module that provides both inputs and outputs.

FIG. 2 shows an output module with more than one type of electrical interface to field devices.

FIG. 3 shows an input module with more than one type of electrical interface to field devices.
