Honeywell FC-SAI-1620M Safety High Density Analog Input Module IO FTA

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.

IO FTA

The FTA module for IO converts input field signals to values appropriate 

for the Safety Manager input module being used,or converts Safety 

Manager output module signals to values that can be used in the field.

For this conversion, the FTA can be used in combination with

an input conversion module or an output conversion module.

FTA modules are available in widths of 70 mm (2.76 inches)

or 109 mm (4.29 inches) and in lengths of 90 mm to 300 mm

(3.54 inches to 11.81 inches), depending on the FTA type.

The modules are mounted on standard DIN EN rails (TS32 or TS35 x 7.5).

The FTA may contain electronic circuitry to convert standard Safety Manager

 signals into specific signals with characteristics required by the field device.

When connected to the Safety Manager IO module, all FTAs use the standard 

system interconnect cable FS-SIC-0001.field cables are connected to the terminals.

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.
