MTA

Preassembled cable with front connector

The terminal modules SIMATIC PCS 7 MTA (Marshaled Termina- tion Assemblies) enable simple, fast and reliable connection of field devices, sensors and actuators to the I/O modules of the ET 200M remote I/O stations. They can be used to significantly reduce the costs and required work for cabling and commission- ing, and prevent wiring errors.

The individual SIMATIC PCS 7 MTAs are each tailored to specific I/O modules from the ET 200M range (see design for assignment table). MTA versions are available for standard I/O modules as well as for redundant and safety-related I/O modules.

The SIMATIC PCS 7 MTAs are connected to the I/O modules us- ing 3 m or 8 m long preassembled cables.
