Product features

• 4 analog voltage inputs usable as differential inputs

or as single-ended inputs

• Resolution 14 bit

• Sensor failure detection

• Electronic parameter chip

Short description

Analog input module KeConnect AI 240/A features four analog voltage inputs that process differential or ratiometric input

signals in the range from ±10 V or 0-10 V with a resolution of 14 bit.

A sensor failure, should it occur, is reported to the higher-level central module and can be evaluated in the application.

This module is attached directly to a CPU module or can be operated with all KEBA controls by means of a bus coupler.
