Selecting and Placing I/O
Using This Chapter
Selecting I/O Modules Select I/O modules to interface your PLC-5 controller with machines or
processes that you determine while analyzing your plant operation.
Use the following list and table as guidelines for selecting I/O modules and
operator control interface(s).
• How much I/O is required to control your process(es)?
• Where will you concentrate I/O points for portions of an entire process
when the entire process is distributed over a large physical area?
• What type of I/O is required to control your process(es)?
• What is the required voltage range for each I/O module?
• What is the backplane current required for each I/O module?
• What are the noise and distance limitations for each I/O module?
• What isolation is required for each I/O module?
