I/O boards convert incoming electrical signals from the process controlled, so that they can be
further processed in the processor module. Outgoing signals are adapted to their functions in the
process. I/O boards are divided into the following groups:
• Digital input boards
• Digital output boards
• Analog input boards
• Analog output boards
• Pulse counter/frequency measurement boards
• Positioning boards
•Others.
Connection units and wiring which connects boards and connection units are associated with
each I/O board.
You can exchange I/O boards while the system is running. You can also insert new boards live,
provided they are predefined in the data base. A newly inserted board is taken into operation
within 10 seconds.

An I/O unit in the S400 I/O system corresponds to an I/O board in S100 I/O.
I/O units are divided into the following groups:
• Digital basic units
• Digital expansion units
• Analog units.
You can connect process cables directly to the I/O unit’s terminal blocks.
You can exchange an I/O unit while the system is running. You can also install new I/O units
live, provided they are predefined in the data base. A newly inserted I/O unit is taken into
operation within 10 seconds.

An I/O module in the S800 I/O system corresponds to an I/O board in S100 I/O.
I/O modules are divided into the following groups:
• Digital modules
• Analog modules.
• Pulse counter / frequency measurement module
• Digital and analog modules with Intrinsically safe interface
• Analog modules with Intrinsically safe interface and HART communication.
You can connect process cables directly to the I/O module’s terminal blocks.
You can exchange an I/O module while the system is running. You can also install new I/O
modules live, provided they are predefined in the data base and there is a free Module
Termination Unit of right type in the station. A newly inserted I/O module is taken into
operation within 10 seconds.
