Selecting terminal blocks
Select the terminal block for the slot of an I/O module based on the following dependencies:
● Definition of I/O modules associated with a potential group
● Requirement for configuring redundant I/O modules
● Parameters of the required I/O module (number of process terminals, temperature
detection)
You can find additional information on this and the technical specifications in the section
"Technical specifications - Terminal blocks (Page 153)".
Plug the terminal blocks into carrier modules.
Note
Voltage in a potential group
● A mixed configuration of I/O modules with different signal voltage is allowed within a
potential group.
● The supply voltage for all I/O modules is: 24 V DC
You can find additional information on this in following sections:
● Section "Forming potential groups (Page 34)"
● Section "Installing the terminal block (Page 71)"
● Section "Wiring the terminal block (Page 86)"
