1.4.1 Analog Input/Output Modules
The analog input module receives analog signals and converts them into internal data in safe-
ty control unit. The analog output module converts internal data to analog signals and outputs
them.

ypes of Analog Input/Output Modules
The following types of analog I/O modules are available in ProSafe-RS:
• SAI143: 4 to 20 mA input, 16 channels, module isolation
• SAV144: 1 to 5 V DC/1 to 10 V DC input, 16 channels, module isolation
• SAT145: TC/mV input, 16 channels, isolated channels
• SAR145: RTD input, 16 channels, isolated channels
• SAI533 : 4 to 20 mA output, 8 channels, module isolation

The connections with the analog I/O modules vary with the types of adapters. Pressure clamp
terminals, terminal boards (with signal cable interface adapter) and MIL cables are used for
the connections. Since SAT145 and SAR145 have a built-in signal cable interface adapter,
they can be connected only through the terminal board.
