KEBA KeConnect AO 240/A Analog output modules

Product features

• 4 analog voltage outputs

• Resolution 12 bit

• Electronic parameter chip

Short description

KeConnect AO 240/A is an analog voltage output module. The outputs produce signals in the range of ±10 V with a

resolution of 12 bit.

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