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?
