The M1 Automation System's wide range of digital I/O modules means there is a module for any channel type. A selection from the standard 6-channel variant up to the ultra-compact 80-channel module guarantees the right module for every purpose.  

Combined I/O modules allow the operating mode (DI / DO) of each individual channel to be configured by the user. As well as the global standard 24 VDC input signal, 48 VDC modules are also available for the power station sector. 

Bachmann electronic's M1 I /O modules not only allow the process image access typical of PLCs but also direct access at any point in the program. This makes it possible to configure individual digital inputs and their status changes as interrupt sources so that programs can respond to process-controlled inputs. All modules support transmission via FASTBUS (fiber optic cable), CAN or  PROFINET and offer a high degree of  flexibility in the design of sophisticated automation solutions.
