Connection examples for redundant I/Os

MTA terminal modules (Marshalled Termination Assemblies)

MTA Terminal Modules
MTA terminal modules (Marshalled Termination Assemblies) can be used to connect field
devices, sensors and actuators to the I/O modules of the ET 200M remote I/O stations
simply, quickly and reliably. They can be used to significantly reduce the costs and required
work for cabling and commissioning, and prevent wiring errors.
The individual MTA terminal modules are each tailored to specific I/O modules from the
ET 200M range. MTA versions for standard I/O modules are also available, as for redundant
and safety-related I/O modules. The MTA terminal modules are connected to the I/O
modules using 3 m or 8 m long preassembled cables.
Details on combinable ET 200M modules and suitable connection cables as well as the
current MTA product range are available at this address: Update and expansion of the MTA
terminal modules (http://support.automation.siemens.com/WW/view/en/29289048)
