Communication FTAs

FTAs used for communication purposes are connected to a channel of the Universal Safety Interface (USI).

Two communication FTAs are available:

– Ethernet FTA, UCOM-HSE, or SDW-550 EC are available:

– Automatic switching of the 10Mb/100Mb Ethernet interface.

– The Universal FTA, DCOM-232-485. provides an Ethernet FTA, UCOM-HSE, or SDW-550 EC.

– RS232

– RS485

Cabling

System Interconnect Cables (SIC) connect field signals to IO modules.

Depending on the type of SIC cable, an FTA is required to establish the connection.

All Safety Manager IO modules are galvanically or optically isolated

between the external and internal power supplies.

Safety IO modules are available for safety circuits up to SIL3 and SIL3.

Safety modules can also be used in control applications to provide 

Safety Manager diagnostics and fault reporting with or without automatic fault isolation.

(The automatic fault isolation feature is configurable).

Field Interface

Safety Manager™ uses Field Terminal Assemblies (FTAs) and internal cables

to connect IOs and communication channels to field terminals.
