LOGO! modular expansion modules

Logic module LOGO! - flexible expansion modularity

Description

A wide range of modules allows individual expansion of LOGO! to 24 digital inputs,16 digital outputs, 8 analog inputs and 2 analog outputs!

The use of serveral LOGO! 0BA7 units allows to expand the overall system to a max. of 88 digital inputs, 80 digital outputs, 40 anlaog inputs and 18 analog outputs.

Communication modules are also available for AS-Interface and KNX (KONEX the former EIB network for building automation). It is also possible to use the analog output module to solve simple closed-loop control tasks. Heating and cooling systems can be designed with the AM2 RTD module (forPT100/PT1000 temperature sensors) using special functions for PI control, ramp response and analog multiplexer.
